ok i got a nitro rustler and i like it

the problem is im running it rich enough and it still overheats and smokes[:@]i hate it when that happens
if anybody had that problem please help me because i need to run it[:@][:@][:@][:@]

set the carb back to the factory settings and try from there. the trx2.5 can be a very picky engien to tune. if that doesnt work then you might have an air leak, you can find an airleak by letting the engine idle and spraying some soapy water around the engine and look for bubbles. another way is to spay wd40 on parts of the engine and if if it cuts out or stalls then you found the leak.

too rich wil actua;;y overheat a engine too! listen to N-Rusty though set it stock clean the heatsink and fins and check for air leaks![>:]

thanx alot hope it works
