noo thats means the car is taking too much fuel through, or if it isnt alot of liquid then it may be ok for that model ?

when cars first start you sometimes see unburnt fuel bripping out the exhaust... mind you this hasnt started :(

so no its probably a sign of the engine flooding, id persoanly would disconnect the fuel and keep pull starting it till its all out, then re-connect the fuel line and try again,

cheers,

Matt

Hello Keith,

    Thought I might add this for you.You should have two ports on the fuel tank---one is the main fuel -out-line to the carb.The second is the vent that goes to the nipple on the exhaust pipe.The vent line when hooked to the exhaust muffler receives a little pressure when the engine is running and gives a constant supply of fuel to the carb----They will not run right (if at all) without this line attached to the exhaust muffler.Pin "holes" in a fuel line can give you problems---

You may allready know all this--but thought it couldn't hurt to post it----- ;D ;D ;D

I used to run nitro trucks, and they can be tricky little beasts.

I will run through the check list, even though it includes what has already been mentioned:

Drain tank
Remove glo plug
Pull cord about 10 times to get fuel out of the system
Leave it for 10 minutes so that any that is left evaporates
Check the igniter is fully charged
Test the plug in the igniter
Check exhaust is sealed properly
Connect fuel line
Put fuel in tank
Insert glo plug - ensure it is tight just pinch it up, no more
Now pull starter a couple of times
If it doesn't start, try operating the throttle while you pull the starter. You may need two people for this.

If it still doesn't start then you need to find the manufacturers settings for the idle and mixture screws. Try the internet, someone will know what they are as this is a popular truck.

If it remains a pig to start consider a Rotastart. I had two HPI MT2's. They were horrendous to start with a pull cord, but fired up instantly on a Rotastart. You can usually buy a conversion plate that simply bolts onto the back of the engine.

...oh and invest in a failsafe, if the TX signal gets jammed then you will not be able to stop your truck as it careers at full throttle for the nearest tree!
