Alright, I got the nami out for a little bit this weekend. I stripped out first gear, but I think it was my fault, I changed out a dogbone, and I don't think I got the trans back in the way it should have been, but that's no big deal. But I have noticed that something is up with the tuning or something. It makes a slight hesitation when I go from 0-WOT also when it hits full throttle it seems to be a little slugish, doesn't like it. I've gone back to factory settings, and re-tuned but I can't seem to get it. I switched from traxxas top fuel to o'donnel. It has been running great for the last few weeks, but now it doesn't want to cooperate. If anyone has any suggestions i'm all ears.

Holy crap. That is very impressive! What's original on that still? Just the frame? Have you posted a breakdown of everything you've done to this rig yet? I can't wait to hear how this performs.

There's not a lot of exposed shock shaft on those shocks - are you sure there aren't travel limiters installed inside the shock body? If so, removing those would be the easy way to increase the extension on the front

Can anyone suggest a good way to clean out any residue that may have built up inside my engine and carb?

You can spray it down with some carb cleaner. Just make sure you flush out whatever debris there might be before you run it again.

brett i use wd-40 and nitro force by dynamite to clean out my motors. on the tuning i had the same problem with my nami i changed the glowplug re torqued the head screws and cleaned out the exhaust sometimes it loads up with oil and chokes the carb. another thing that might be messing with your tuning could be the o-rings on the tuning needles check those. and your outside temps have they changed since the last time you bashed? and is it below 35? nitro fuel pull moisture out of the air and the water will freeze or jell up a good way to check for freezing or jelling nitro. hold up your fuel pump bottle to the sun or light and look for little floaty like things. looks like oil when you put water in it.

Thanks retro. I did change glow plugs, but I didn't think to check the o-rings on the needles. I'll definetly do that. It has been pretty cold here lately. It's gotten down into the lower 20's. I"m sure that isn't helping anything. I figure most of the problems I'm having is due to the traxxas fuel, it's is really oily and has left all kinds of residue all over my truck. I looked up in the exhaust and it's like totally black with oil all in it, so I assume the carb and probably the inside of the engine is probably the same way. Hopefully after I get it all cleaned up and check the o-rings ( I'll just go ahead and change them out regardless what they look like ) it'll be back running strong. This is the first time I"ve had any problem with the engine or tuning since I originally tuned it after breakin, all I've ever had to do is richen the hsn a little bit for the cold and it's been running great till this past weekend. I'm sure it's long over due for a good clean out.

brett when changing fuel brands and nitro content you need to do a 2nd break in with the new fuel. im pretty sure its your outside temps thats causing you tuning problems. your motor might be cooling down too fast with the cold air rushing in try wraping some tin foil around the cooling head make sure your fuels oil content is no less then 16% the vertex and most motors are designed to run on no less then 16% oil content traxxas uses like 18 or 19%. i think its alot. i run morgans fuel backyard basher and i like it plus its only 30 bucks compared to top fuel 45 bucks gal. morgans fuel also makes sidewinder.

I did swap brands, but not nitro content. I'm still using 20%. It's a little too late to do another breakin. I've already run over a quart through it, but it was running great for many tanks, then I put it up for about a week while I was waiting on parts then got it back out and for the first tank it was running fine, then during the second tank it started giving me problems. But I'm gonna clean it out and check the o-rings like you advised and see how that does. I'm sure it's something simple. It's not giving me any problems starting or idling. It runs prety good over all, actually if I didn't know this truck like I do then I probably wouldn't even notice that something wasn't right. It's just a little bit of hesitation between 0-half throttle, then a little bit at WOT. Other than that it still pulls well through the RPMs.

p.s... I swapped to O'donnel racing fuel ( not the RTR ). It doesn't tell me on the bottle what the lubricant content is, but the guys at my lhs said it was just fine.

OD's is something 18% if I remember correctly. I found it online somewhere. I found OD to be very oily too and left a nasty residue on everything. Ive been using trinity monster horsepower for a while now and it seems to be working well. It takes a little trial and error based on where you are and which engine you have. Some engines run better on certain brands then on others.
Brett you might want to check your glow plug too. If you have a decent amount of fuel through it then it might be time for a new one.

Yeah, the glow plug was one of the first things I changed. I'm pretty sure it's just alot of built up residue. I've never given it a good cleaning since I've had it, I'm sure it's way over due. But I have another question, I've been using O.S #8 plugs I know they're a medium hot plug. They've been working really well, but what about the LC3's I know they're a ultra hot plug so would they be alright to run in the cold? or would I be looking at doing some damage? With the higer lubricant content in fuels I would figure they might be alright to run in extreme cold.

Im not positive on the plugs. I know they say the smaller engines like a hotter plug but the ultra hot might be too hot. Eminent should have some input on the plugs since hes up north.

I found that the sidewinder fuel was the best that I have ever used not to much oil but just enough. Im using 25% because thats all they have here i sidewinder. Were starting to get alot of snow now. You dont have to do another breakin process when you change brands or nitro contents. You can only break in an engine once there is no way to break it in another time all the breakin does is matches the piston and sleeve together the new sleeve has been honed from factory to make it like a really really fine file and after you run it they pritty much just wear together to ensure that there is the best seal between the sleeve and the piston. The only reason that some people say to "break it in" again is to make sure that you dont end up leaning the engine out.

I took the revo out bashing in the snow the other day the clean up after sucked but it was worth it.

the 2nd breakin comes directly from OS engines. the lc3 is intneded or the os21tm for this time of year i would use the A3 plug its hot and by 2nd break in i mean run the truck as if you were breaking the motor in.

I didnt get any pics man next time I will make sure that my phone is charged up its to cold to bash right now or I would go do it right now lol I hear that its going to be around the -20 mark for a while......... bugger. I put some tmaxx tires and rims with a wider ofset on my revo ill post some pics tomorrow just keep bugging me so I dont forget lol. I want to drive my mt2 but I have been waiting just about 2 months for some e clips to come it........ thats all thats stopping me from running it. I think I found a company that makes some plastic cv shafts that might fit the tsunami. I was on a road trip for the metallica and lamb of god show in edmonton and stopped at a store that sells pocket bikes and quads they had an rc on the wall for sale that was just about the same as the tsunami with plastic cv shafts in it. So im going to track down some part #'s for them and see if they will work.

What brand was it?
I wish I knew you needed the e-clips. I had ordered some from killerhobbies.com a few weeks ago. I think it was a going out of business sale because I dont see any RC stuff listed on their site anymore.
Do you have an acehardware by you? They might have them, or true value hardware.
Actually try this link http://www.truevalue.ca/pls/truserv_pub/truserv.app

What in the world would is going on up there that it would take 2 months for something to be delivered? That's a long time to wait just for some e-clips. I would be going ballistic!
