scottpep -> stalls (4/30/2008 3:40:35 AM)
i have an aftershock and have tweaked the settings abit and am gettin kinda stuck here..... when i start it it'll idle but as soon as i touch the throttle it stalls. would this be caused by the idle dial in the back? or the low speed? it seems like it floods as soon as i bailry touch the throttle.. once its warmed up its ok but the first run i REALLY have to ease in to it and it takes alot of effort.

scottpep -> RE: stalls (4/30/2008 4:17:16 AM)
anyone know the stock settings for the idle on this truck? i know the low and highspeed are both 3 turns out.. so im not runing it too rich........ im wondering if i may have set my idle way off causing this..

str8jailbird -> RE: stalls (4/30/2008 5:43:12 AM)
take off your air filter and check your gap opening. It should be about 1mm. If it dies when you hit the throttle when cold that means its a little rich. Not a big issue, just let it warm up. I have the same situation with my LRP in my LST2. After letting the truck warm up a tad I take a few slow runs to get the temp up and once it is WATCH OUT!

scottpep -> RE: stalls (4/30/2008 1:17:44 PM)
how long do you usally warm em up for?

RCtruckRacer -> RE: stalls (4/30/2008 3:05:30 PM)
Try starting with the wheels off the ground so that you can give it some throttle the moment it starts to fire. That will help clear the chamber.

scottpep -> RE: stalls (4/30/2008 3:20:00 PM)
that helps.. but IT STILL doesn't work when its cold.... the only thing im unsure of is the idle screw in the back... i don't know what the factory settings are either and its not in the manual haha

jaron_denson -> RE: stalls (4/30/2008 4:38:06 PM)
I would say back that thing all the way off and start it without an Idle screw, the Idle screw if into far can cause a dead spot down low. Also I think that your low speed it too rich. Try leaning it out.

RCtruckRacer -> RE: stalls (4/30/2008 5:22:41 PM)
Removing the idle screw will mean the carb closes all the way shut at idle or brake. That will shut the engine off. The stock setting for the idle gap is 1 mm. Set the idle screw so that the carb is open 1mm when the linkage is at neutral and on brake.

scottpep -> RE: stalls (4/30/2008 10:58:09 PM)
so i was out too far and the gap was maybe 1/2 mm.......... i made it quite a bit bigger.. the idle is high now but hey. it starts and runs :>:>>:>:>:> the ht pipe and new air filter i got on there make this thing a rocket..

scottpep -> RE: stalls (4/30/2008 10:59:19 PM)
thanks for the help.. without these fourms i would have sold it for parts by now hahaha... althow.. 2 pull starts and a dead glow plug and settings out of wack isn't too bad... my buddys purchased a mamoth xt and a tmaxx at the same time and the aftershock is holding up WAY better

str8jailbird -> RE: stalls (5/1/2008 4:23:11 AM)
Yeah can't beat a Losi (although I try my hardest!). I have a T-maxx 2.5R that I bought off of a pal at work for $75.00 . I like the T-maxx for running in the yard but as far as the slate dumps and tracks are concerned the LST2 wins hands down.

scottpep -> RE: stalls (5/1/2008 8:20:07 PM)
i beat the heck out of it last night. my friends tmaxx broke again.. losi held up.

str8jailbird -> RE: stalls (5/1/2008 11:32:23 PM)
Yeah, I was running both of mine today and the T-Maxx TRX 2.5R fried! No warning whatsoever, no bogging, no cut-out no hesitation and no overheating! Now I gotta find another engine that doesn't begin with TRX, LOL. That one only had about 1.5 gallons thru it! If I get the extended chassis for the T-maxx I might drop in my old Mach 427! I just don't think the tranny and drive train will handle it![>:]

scottpep -> RE: stalls (5/2/2008 4:47:20 AM)
haha i had my aftershock flying down sets of 9 stairs and landing great... i wiped out so bad once my cover was inside out lol but no real damage

BioRev -> RE: stalls (5/2/2008 5:50:50 PM)
If you have the stock engine that came with the aftshock then the stock needle settings ARE in the manual. Its 3 turns out from bottom for both low and high needles. As for the stalling my spec 3 does the same thing. I have to let it warm up for atleast 5 mins with the throttle on just enough so it doesn't stall but warm up quicker. Once it gets warmer the high speed leans out naturaly and shes a monster on full lol.

scottpep -> RE: stalls (5/2/2008 6:03:42 PM)
actualy the factory settings for the low and hi speed are in the manual.. wich i knew already... but for the idle screw in the back they are not... i have doubble checked and looked around for them and was unable to find them. its good now and runs great.. just had it idleing quite low so it would stall as soon as i touched the throttle

I don't think that the Aftershock would be much different from that.

nitrojimbo -> RE: stalls (5/5/2008 1:05:39 AM)
hi i have a question. i have an axial 28 in mine and i broke it in today and it did fine. then i decided to go and run it just normal on the ground(i did the heat cycle method on a block of wood). but it will only go like 2mph max at full throttle. the slipper is fine and it will grab great but i dont know wats wrong.[:'(]

str8jailbird -> RE: stalls (5/5/2008 12:19:13 PM)
Is it revving out, bogging down???

BioRev -> RE: stalls (5/5/2008 12:54:45 PM)
Mine just started doing that after break in, Havn't had time to tune the needles correctly. whats the cause?

nitrojimbo -> RE: stalls (5/5/2008 2:18:45 PM)
well it just doesnt go anywhere at more than 2mph and i kinda tried tuning it but eben if its at stock settings it should go ATLEAST 30mph or something like that

str8jailbird -> RE: stalls (5/6/2008 2:06:47 AM)
And I ask again, is it revving out, bogging down, what is it doing. I can't believe that the engine is hitting high rpms and the truck is only barely moving. If that is the case then it is not an engine malfunction. If you hit the throttle and the engine bogs down then it is too rich. If you hit the throttle and it cuts out it is too lean. If you hit the throttle and it almost hits higher rpms and bogs down then it is still rich. What exactly is it doing? You can't ask a doctor to diagnose you just by telling him you don't feel well. Not trying to be a smart alec just need a little more info on the problem.[:D]

BioRev -> RE: stalls (5/6/2008 12:58:33 PM)
If your motor is fine but it struggles to go forward then its probably tranny or OWB related. I agree with Str8 tho, Tell us in detail whats going on, Going only 2mph only tells me that ur tranny or OWB has problems, Freely roll the truck back and forth to feel if theres any resistance or friction, If not check to see if your flywhell spins freely or maybe the case is with your gears, I've seen improperly adjusted gears where they are very tight against eachother, as in the manual it talks about how proper distance between the sprocket and gears must be proper or else it may cause to much for the engine and you get crap speed. If that isnt the case then i don't know.

nitrojimbo -> RE: stalls (5/6/2008 2:14:04 PM)
well it does bog down a litte only because the stock settings are slobbering rich. me and my dad think its a clutch problem like BioRev said

sillared -> RE: stalls (5/6/2008 2:49:08 PM)
Hey Nitrojimbo.. Lets try this question again, its VERY important for us to know, to be able to even think about helping you correctly.. Is the engine screaming like a formula 1 car when you tap the throttle with the wheels off the ground, making you wonder if the thing is gonna blow up?? If so, something in the driveline is slipping and the engine is running ok. Also, do you have a temperature gun/gauge?? What temp is the motor running at? IF, its slobbering rich like you said... engine will be boggy as hell, leaving all kinds of fuel on the ground from the exhaust... if you let it idle in one spot for 5-10 seconds and theres a huge wet spot, you are wayyy tooo rich, and the engine isnt producing any power... A slobbering rich engine, or a cold one sometimes for that matter, will give you a top speed of 2 mph.... Trust me, been there... and I`m still a noob myself... Stock break in settings are wayyyyy too rich, you need to lean the motor out on the high speed needle and the low speed needle 1/8 turn at a time to get your 30 mph or more... Others here are much better at tuning than myself, so if they want to jump in and explain, go right ahead... E.
