I just wanted to let everyone know that I got that troubled 50cc scooter of my brothers fixed, I had checked all the electrical system and the fuel delivery and it was all checking out good so today I did a compression test and it was just as I had thought when I first cranked the engine over by hand on the kick starter.....very low..... were talking 32-34psi, so I pulled the valve cover and turned the engine to the TDC position and by hand checked for clearance between rocker and valve, the intake had about .004 and the exhaust had .000 it was actually a minus clearance the valve was being held open, so I backed it off and gave it a .004 clearance and checked compression again and shazam.....! I got 135psi on the gauge that time and that was just using the kick starter, put it all back together and the little fellar fired right up and purred like a kitten, I thought it had about 200-300 miles on it but I was mistaken, it has 2,153 miles on it and has never had a wrench on it of any kind so I would say its been a good one thus for, it's one of those Velocity 21th like www.scooterdepot.us sells for about $500-$600 bucks, all I was out was a $42 compression gauge with the 10mm adapter which I picked up at our local Advance Auto Parts store. now I have 3 Compression Gauges.....LOL all I needed was the 10mm adapter but had to buy the whole thing, Oh well got-ur done any how......, just wanted to let you know what it finally took.

Here is model scooter I been working on (Not Brothers Scooter)
