get some extra plugs and try them. go back to the normal ones too. the a3 ones and see if it will fire then. is it rebuilt? does it need a rebuild?

[t-maxx 101]

what do you mean by rebuild i have never done that before what do you mean by rebulid.

[t-maxx 101]

and also what are all the neddle setting high speed low speed and land the idle screw please tell me it.

[tadium54]

a rebuild is when the piston and sleve can't hold together anymore.if you can turn the engine over without feeling a pop or any resistance, it needs a rebuild. you take it apart, replace the piston and sleve, put it back together and go through breakin again

[t-maxx 101]

how on earth do know it needs a rebuild it will start once in a blue moon but when it does work it can't stay running for more than 10 seconds what are the neddle settings i don't remember i messed with the neddles so much.

[QUAKE&SHAKE]

Try 2 3/4 turns out on HIGH needle.
3 3/4 turns on low needle or just flush with the carb housing. About 1mm opening on the idle setting.
Oh and yeah charge the glow-ignitor fully. As far as what plug I cant make a comparision all I have used is A3 plug no issues at all with that plug it is cheap and lasts I use it in 30-85 degree weather.

you don't think it is my fuel quake and shake i am using trinity 20% nitro horsepower the purple **** you don't think it's my fuel

[Handybugz]

i use trinity fuel so you should have no problem with this stuff i think it works great and with your engine problem my engine was doing the same thing and all i did was start from scratch with the needles come to find out the engine was running way to lean but i was still able to get 5 gallons through it before i had any trouble with the engine.

[tadium54]

how old is the engine. how much fuel has gone through it? how old is the fuel?

[QUAKE&SHAKE]

Has the lid ever been accidently left off for a long time?
Trinity 20% will work just fine if its not gone bad. I use 20% Wildcat fuel. From what Ive read Wildcat makes Trinity fuel. The RCCA guys use Trinity all the time in their reviews so if the fuel you have is good the problems you have arent with the fuel itself.

Use the duratrax gold racing plug with 20% fuel.It is a cold plug.This is whaat I do and have had not problems.duratrax recomended the gold plug with 20% call them if you want.high neddle 2 1/2 turns low flush with housing.
