Hi i have been having a problem with an old kyosho gt12 engine,i just got it out of the attic (the engine is in the car) i started it drove it and if you put on the throtle too quick it will die and if you slowly put it on and go past the half throtle mark it will stall and it will not idle.

what is wrong help please.

Thanks [&o]

low end i think? if not maybe its too rich

hi the engine dose not have a low end just the one main one and idle i have tried differant settings but no look i am running it on model fule (some cheapo brand i thought i would try)
it is 10% nitro but i have some bluethuder 20% for my hyper 7 buggy shall i try that fule in it?
and some one told me to check for air leaks could this be a problem.


Thanks[sm=thumbup.gif]

Maybe use the fuel or get extra fuel tubing for the gas to the carb.

well open your idle to 1 mm when the brakes are applied and on idle and set your other needle flush with te valve stem that should get it? idk about these 2 neddle carbs kinda tricky you would think

thanks if that does not work could the engine just be warn out (no compression)

Thanks

sure it could be done.. piston and sleeve worn
