fishypatis28 -> Problem with Savage X 4.6 Start Up... (5/9/2008 6:40:35 AM)

Hello All,

I am a "Rookie" at this site and a "Semi" rookie at R/C cars. I finally broke down and bought the R/C car of my dreams a Savage X 4.6 RTR. I bought it two days ago and I have been trying to "Fire" it up. But so far it has been unsuccessful! =( Is there any advice from any professionals out there for this poor rookie? Any help or advice will do. I've done research on YouTube, Manuals, and Internet but still no avail. The engine has been Primed and I believe it almost started once. I've done the warming up the engine outside bid and the Heating up the engine block bid too. I know that any advice from the professionals will help me dearly! Thanks a bunch!

The Rookies of all!,

Fishypatis28

Lean it out about 1/8th a turn.... Check to see if the glow plug is good, make sure the glow ingiter is fully charged. More advise should be coming soon

im not a professional or anything but your glowplug might be burnt you might have got a bad one. or you fludded the engine so you should take out the glowplug and get all the fuel out




c_P -> RE: Problem with Savage X 4.6 Start Up... (5/9/2008 7:26:10 AM)

with the new roto-starter if your engine is flooded or watever that red button will pop out




fishypatis28 -> RE: Problem with Savage X 4.6 Start Up... (5/9/2008 7:29:16 AM)

the roto-starter button has popped out a couple of times. Should i just remove the glow plug and clear out the engine as instructed in the manual? Then replace the glow plug and try it again?




fishypatis28 -> RE: Problem with Savage X 4.6 Start Up... (5/9/2008 7:31:25 AM)

do you think i could have burnt out the glow plug from constantly trying to start it up?




c_P -> RE: Problem with Savage X 4.6 Start Up... (5/9/2008 8:54:57 AM)

Not sure how it can be burnt out but to check if it's still good, the some pilers and hold it so you can hold the glow ingiter to it to see if it light up. If the red button popped out a couple of time, when your checking your glow plug, unflood the engine like the manual shows.

Hope that helps

Like people said, check the plug. Blowing hard into the glowing element will tell you in what shape the glow battery is. If it is easy to "blow out" the glowing element, your battery may be dead or weak. Plugs draw a lot of current, and that battery will drain fairly fast with repeated starting attempts.
Plugs normally don't die from flooding the engine, or repeated starting attempts. And anyway, it's easy to check: take it out and put it in the igniter to see if it glows.

Unflood the engine.

Don't fill the tank much over halfway for the first starts. If you do, fuel tends to siphon into the engine, making it very easy to flood. This is especially true if you have a pullstart engine.
In fact, I never fill my tank over halfway for the first start of the day. After the engine has been run it starts a lot easier (I run a lot of Castor oil in my fuel, which stiffens up during the night, making the engine harder to start)

If it still drowns during starting, you can close the low speed needle 1/4 to 1/2 turn to see what that does. These needles are usually set VERY rich from the factiry. But make sure you properly set the needle before attempting to drive the car for any amount.

If you have a Rotostart, you shouldn't have to prime much, provided the "idle gap" in the carb is set correctly. Check your manual to gap the carb for a proper baseline idle setting (it's usually about 1mm). If fuel doesn't move in the fuel line, you can close off the exhaust shortly while hitting the Rotostart to prime the engine. Don't overdo it as this will quickly flood the engine.

Leave the body off while you're setting the engine up. That makes it a lot easier to get to all the controls.




splcrazy -> RE: Problem with Savage X 4.6 Start Up... (5/9/2008 11:11:30 AM)

i had the same problem with my savagex 4.6 , this engine is just a bugger to start , make sure your glow ignitor is fully charged and your roto start batt is fully charged , and try not to flood the engine while starting and yeah try leaning the needle just a bit just so you can get it to start then richen it back again when the engine gets warm , keep doing this untill youve fully run it in , ALSO i found by using OS A3 glow plugs on this engine its ALOT easier to run




fishypatis28 -> RE: Problem with Savage X 4.6 Start Up... (5/10/2008 8:59:59 PM)

Thank you all for the tips on troubleshooting my Savage. I haven't had time til today to check up on my Savage but I was able to pull out the glow plug last night and notice that it's still good to go. So now I am going to attempt to clear out the engine and try the set up again. Wish me luck and hopefully it will fire up this time. =)




BudBud -> RE: Problem with Savage X 4.6 Start Up... (5/10/2008 9:14:08 PM)

Turn your throttle trim up a little too, so that the carb is open a little more than at idle. Should be a button or knob on your transmitter for that. It will help the engine get that precious gulp of air it needs. They are also much easier to start if you will make some sort of starting stand, like a PVC pipe frame or even a stack of 2x4s to keep the tires in the air while you are firing it up. That way the engine does not have to fight the clutches when it makes that initial fire, it can just spin the drive train. I agree on the hour leaner on the high speed needle, probably the low speed as well. Keep us posted, I am not pro either. BB




fishypatis28 -> RE: Problem with Savage X 4.6 Start Up... (5/10/2008 11:38:03 PM)

OK. I think I am making progress. I was able to start the Savage for a split second twice. But after that I couldn't get it to start again. It's been years since I last played with an R/C car so I am pretty amped to get this one broken in. After, both quick starts. I wasn't able to start it again. When I kept on using the Roto Start I could see a little bit of smoke comming form the exhaust. Any tips on what I can do to finally get this going on? I have it sitting on a large 5 gallon bucket right now. THANKS FOR ANY HELP IN ADVANCE!




twomanytoys -> RE: Problem with Savage X 4.6 Start Up... (5/10/2008 11:46:18 PM)

I can usually just blip the throttle as I turn it over and it will fire. Have you primed the engine correctly?




fishypatis28 -> RE: Problem with Savage X 4.6 Start Up... (5/11/2008 4:10:42 AM)

Sucess! I finally got the engine to run! But the only problem now is that everytime I take off the Glow Plug Igniter it craps out and I have to start it again. Any advice?




BudBud -> RE: Problem with Savage X 4.6 Start Up... (5/11/2008 5:02:30 AM)

That is too rich. Try an eighth turn in on both needles. They want you to run insane rich to protect the engine. You can also run it for a little bit in the glow charger. I grab mine by the back bumper or wheelie bar and do a little front tire burnout to help build some heat in the combustion chamber. They can be obnoxious little buggers! BB




Rudeboy -> RE: Problem with Savage X 4.6 Start Up... (5/11/2008 2:00:00 PM)

Yep, too rich... lean it out some. The high speed needle has very little to do with starting and idle. The low speed needle is what controls the mixture at idle.
Leaving the glow starter on to warm up the engine can help too.
But if it is too rich, it will eventually load up again if you remove the glow starter.




twomanytoys -> RE: Problem with Savage X 4.6 Start Up... (5/11/2008 2:13:07 PM)

I usually leave the glow starter on for the first min or so to help warm it up and durring that time you can drive it around. Then you can lean it out a little to keep it running.




fishypatis28 -> RE: Problem with Savage X 4.6 Start Up... (5/11/2008 11:54:28 PM)

I was going over the maual and I notice it said take off the air filter and and adjust throttle linkage. Is that necessary since the air filter is being held down with a twist tie? Just wondering.




BudBud -> RE: Problem with Savage X 4.6 Start Up... (5/12/2008 12:21:00 AM)

They have you do that so you can see how far the throttle is open at idle. When you get ready to adjust your linkage you will also want to check to make sure it is opening all the way with the radio. You cannot see the hole with the air cleaner on... BB




fishypatis28 -> RE: Problem with Savage X 4.6 Start Up... (5/12/2008 4:44:03 AM)

Ok, so now I had my friend help me start up my Savage and he did all of these tweaks to the car. Now it runs but when we take off the glow plug igniter it cuts off and when I try to rev it up it also cuts off. My friend just left and now I'm stuck trying to figure it out. I think he may had good intentions but now I think he made it worse. Any ideas? Thanks in advance![:D]




BudBud -> RE: Problem with Savage X 4.6 Start Up... (5/12/2008 4:57:05 AM)

Is the the K4.6? Start with the needles flush.... turn the low speed needle in one quarter turn as we already know it is way too rich at stock setting. Now drive it in a circle, prefererably someplace that is pretty smooth, a parking lot or short grass. Watch this video and as you start getting lean enough to run fairly well, stop. I wish Hpi would start these out a little leaner. New owners fight them needlessly. Drive it with the glow charger on if you have to. I am sure that it is so rich that it cannot possible swallow the fuel. BB

Edited to add that I do not think running them super rich is particularly beneficial to the engine either. BB




Rudeboy -> RE: Problem with Savage X 4.6 Start Up... (5/12/2008 7:23:32 AM)

Have someone film what you're doing, and put the video up somewhere.

It'll be a lot easier for people to tell you what's going on when they can see and hear the engine running.

And yes, if it cut out when you remove the glow starter it is either way too rich or your plug is gone.




KILL--ROY -> RE: Problem with Savage X 4.6 Start Up... (5/12/2008 9:22:49 PM)

This is very simple
You are to rich
Lean the motor, start it, warm it up, richen it back up
Do break-in
Tune for performance.
As the motor lossens up it will become easy to start.




fishypatis28 -> RE: Problem with Savage X 4.6 Start Up... (5/15/2008 5:35:03 AM)

Thanks everybody for all of the advice on Start-Up! I am still having issues with it though. =( Here is a video of what's going on with this darn thing. Pardon, the back brace I was doing yardwork and my dogs. They just wanted to play! As always any advice will help and of course will be appreciated! Thanks in advance!

The woeful rookie!




01s0uljah -> RE: Problem with Savage X 4.6 Start Up... (5/15/2008 8:06:11 AM)

Running too rich, the engine accumulates fuel during idle and once you push the throttle, it'll flood the engine and die.. try leaning the HSN and SLOWLY and gradually press the throttle.. up to temp and break it in.. good luck
