Thanks for the info, I know when he did the motor he did the bigger head studs and fixed the crank issues known with the 87's. Waiting on a new intake pipe to come in right now before I can test much more. I was able to patch the old one together long enough to know that it is still running like sit on the top end even on pump. Runs perfect at idle and down low. Also, looked deeper today and saw that it has the aftermarket tansarini motor reed cage or however you spell it. Runs absolutely amazing right when u lay in to it down low and then horrible after that. It's hard for me to believe, from reading everyone else's posts, that it would be running too rich on a 175 main jet but Im going to take it out once the new intake pipe gets here and run it wide open for a minute then shut it off to check the plug then. I just for ****, rebuilt the carb so I know it's all new and I found its running a 58 pilot jet which seems normal. Needle was on 2nd clip up so I switched it to the middle as most people say that works better for them. I think it will just be trial and error.
