Hi my name is fabio i have got a traxxas nitro petrol . the problem is it wont start it is a pull start one and i have took the glow plug out and heated it up but steal dnt wona go any sugestions ?

you need to pull the glow plug out and see if its good visually; look at the coil in the hole in the bottom it should look like a spring unbroken. If you have a glow stick put it on the plug and see if it glows. If you can just replace the glow plug they go bad and it may still look fine.
you need to set your main carb needle to 3 turns out from closed.

Now with the glow plug out place a clean rag over the cylinder head where the plug came out of and use you starting wand to turn the motor over........the rag is there to keep fuel from spraying in your eyes. turn the motor for 5 seconds.

Next put the plug back in and gently tighten it down with an 8mm socket. Put your plug wire back on and try to start the engine for 3 seconds. If it starts up reves high then dies try this.
Put your finger over the exhaust and turn the motor over until you see gas go into the carb the remove your finger from the exhaust and continue to crank the motor for no more than 10 seconds.....she should start now. Adjust the carb according to the manual. Have fun.

Bad glow plug. Dead battery in ignighter. No fuel going to carb.

i always gave mine half throttle for 2 pulls, attatched the glow plug batt, and bam, started right off next pull

Please check your battery and also check your glow plug wire it may be damaged .

check to see if the engine has compression by taking glow plug out and putting finger over the hole and pull the pull start it should pull your finger you will be able to tell if it is without compression it wont be able to pull fuel in there for it wont run

when you get a new glow plug wire a tool is packaged with it and instructions its a small brass tube you slip over the pin to release it.

Hi
2 stroke engines are very simple. If there's fuel (under pressure) and a spark it will run. Check the glow plug by trying to start it with glow plug removed but still connected and touching the engine body. If the little center wire glows bright red, then it's OK. Only do this for a second or so. If the plug is OK then it has to be a fuel problem. Traxxas has a long history of cracked gas tanks. Good luck

Hi
You've checked the glow plug externally to see the wire get red? If so, as long as you've got fuel and fire then it has to start. My guess here is that you have either a bad glow plug, low batteries, fuel air leak or clogged pressure line. Put a charged battery into the starter. Remove the glow plug and try to start - fuel should spurt up through the glow plug opening. Now connect the glow plug and touch it to the engine. Try to start and you should see the glow plug wire glow red. (do this only for a second. Now disconnect the pressure tap from the muffler and try to start. All else fails, replace the fuel line to the carb and the pressure tap. Your carburetor can leak air through the rubber gasket . Also, Traxxas fuel tanks have a cracking problem. Good luck

i'm new to revos two but i just bought a couple and had the same problem with one of them, make sure your glow plug is ok or just replace it and adjust your high speed needle, i'm in oregon i had to richen mine about 1/4 turn. i also noticed both of the models i got were set differently from the factory. there's info on traxxas website on where the factory needle settings should be.

The glow plug could be bad. If the motor turns over and is getting fuel I would replace the glow plug.
