Ok, I swapped carbs. I swapped transmissions. And, now I am ready to pull my hair out! The Sami si running like crap! It'll idle for days without hesitation, no overheating, nothin... But, if I put it underl load it'll run like hell. the engine will backfire, sputter and just plain run like poo. In order to get anywhere I need to run the RPMs up real high and release the clutch halfway. The funny thing is, the car seems to run fine until I hit a bump or backup fast then the problems kick in. Any ideas?
