I have been changing jets. I now have 76 in the primay, and 80 in the back. I can tell the engine really comes on hard when the secondaies open. More now than when I had smaller. That's why I put the 76 in the primary from 70. I figure it likes more fuel. No smoke, but it kinda lopes. I installed an A/F gauge but it stays on RICH, execpt for the instant I hit the pedal and open the carb ... The engine works great...but? Is it optimum?
