OK...so, it's running smoother, and a little better, but it's totally dogging...don't think I still have an air leak...Either I have a bad gear ratio when I switched to the 1 spd (17t clutchbell with whatever gear comes in the one speed tranny I bought...I think it's 44t), those MPI springs are grabbing way too early, or because the Infiniti engine doesnt have a pin in the block to line the piston sleeve up to (does have a notch), I have the timing off (but should be close)...or after how ever many tanks with too much back pressure, I lost the pinch in the engine or something like that...but it is just not building any RPM...It sounds more like a 4 stroke lugging around...after about 25 ft going down hill in my driveway, it started to pick up speed just in time to hit the brakes and turn around, which is why I'm thinking clutch springs...Any more suggestions???
