baja running problem

[jw32baggs]

here is a little problem im having..i was driving my baja and all is fine,great takeoffs,turning,braking etc.but when i am at a dead stop and take off full throttle all is fine untill it almost reaches full throttle,sounds like it almost cant and the truck makes a crackling sound like very mini backfire pops,i have looked over every gasket for proper seals with wd-40 all is good.i think it might be something with the hsn,maybe too lean or too rich?or could it be the spark plug?thanks for everyones input Jay

When you hear that crackling, the motor is breaking up. This means that it is too lean on the HS needle. Try backing it out some and then give it a test run.

it also can mean your way to rich and not all the air fuel mix is burning then the pop you here is the unburned fuel exploding in the pipe. But most likely you are to lean.
