Unknown Rattle

yup....these things are pretty noisy even when they're healthy

This is very true, I still think something is wrong with mine from time to time, lol as long as it sound like a small diesel engine at idle I don't worry, lol. That is the reason I asked when it rattles, but haven't seen a response yet.
 
I out a dynojet kit in, but it is still rinnin lean i think, which i dont see how, but i think it is better. I think that it was Just Cause that said it was pre detonation, so i think he is right, cause it isn't as loud. To richen it, should i just raise the needle?
 
It depends on how tou drive. If youre in the mid rpm, then yes raise the needle. If you are WOT most of the time then go up on the main. Make sure that your pilot jet is adjusted correctly.
