You deserve a swift kick in the *** with steel toe boots for that.

You CANNOT "JET DOWN" A CARBS CFM RATING!!!

You're not the first one to think this but its not even close to right. There's your first problem though. Jet it to the proper specs not the specs of a carb you don't have. Actually id use a rod one step thinner on the primary step from stock meaning it it calls for a 7250 run a 7150. I don't know the stock calibration off the top of my head but we'll start there.

Start there and then come back. 90% of your problem should be eliminated.
