getting onto the subjects of engines, my 3.3 is acting up. it runs great. tons of power and speed in my revo. but it doesnt want to idle. i have the idle screw set as high as possible and still have to turn the trim up on my radio and i cant hit the brakes or the engine dies..... could this be a problem with tuning? what can i do to fix this? thanks in advance

If it dies when you hit the brakes, chances are:

A) the carburetor is closing when you hit the brakes. Shut the engine off, take off the air filter, and hit the brakes. If your carb closes completely, that's your problem. The carb slide could be loose (rotating inside the carb), the idle screw is buggered up, etc.

or

B) the clutch is hanging up on the bell and killing the engine when the wheels stop. If you hold the truck up off the ground, rev it up to clean it out, let off the throttle (so it's basically idling), then push the truck onto the ground and stop all four tires, and it dies...it's a clutch problem.

Could be a broken spring, deformed shoe, etc.

well the clutch spring is real loose and i need a new one so... might be it. the clutch bell is cleaned out though. and the carb does close when i hit the brakes because i have to set it out real far to get it to idle. the slide valve is tight and isnt rotating. what do you mean the idle screw is buggering up?

How many 8ight T's have been produced to date?

I heard some interesting 'tales' that need to be put to bed!

streetracer - I've seen sport engines where the idle screw may not hold the carb barrel in place. Just an idea. If you hit the brakes and the carb closes completely, that is what is causing the engine to die. When you hit the brakes, the carb should still have a small opening, allowing the engine to get air (and stay running).

If the clutch spring is really loose, it may well be a clutch problem.

mabuchi - I'll make another call tomorrow. Last time I talked to them, they were working on getting you taken care of.

horatio - I don't have even the slightest idea, haha.

birkett - Not a problem.

i have a question.... i have alosi gtx and i was wondering if it is possible to run newer losi truck tires on the front and what is needed thanks.

Aaron Waldron

I'm not sure what all would be necessary (as I don't have one sitting here to look at) but you might need just the front axles in order to run the new wheels on your truck. At the most, doing a little bit of hand-modifying to use the XXX-NT (or AD2) front end pieces (from the caster block out) to use the new axles and wheels.

Check for clearance (so the wheels don't hit anything) and you should be able to make something work.

Aaron Waldron

That will allow you to use the XXX-T and MF2 front wheels as well.

Aaron,

What's the theory behind your breakin method? Also, how to you get it up to operating temp with the stock settings? Are you talking about 200+ degrees?
I've always been told that if you do not get the engine up to atleast 200 you are doing more harm than good.

Thanks.
