okay guys, got done to the root of the problems, 1. the front tire needed to be extremley tight to keep balanced, thats good, 2, the mysterious gas tank problem, i looked at this thing in every aspect, couldnt figure it out, then i had a thought, what if its not venting, and is vaccuming fuel up the tank out the cap? at the price of gasket, i folded, it in half putting holes all down inbetween it, wallah no more gas tank leakage problems, and my final almost solved problem, i can get it to idle and rev up, but anywhere before 1/4 throttle it begs for more, over that, you can hold it all day long just fine, i think its just the motor needs more throttle at that point, and it gets it, anyone else think the same? also pulling the spark plug boot up just a lil off the spark plug makes it idle faster, why?
