Most of you know that I clipped my carb spring a few months back and that i never really got a chance to check it out. I did a long ride on Saturday with 2 friends and my son and here's what happened. I probably hadn't gone 2 miles when I noticed that my wheeler wasn't going as fast as I wanted it too. I would hold the throttle wide open but it would only go about half throttle, if that. So when I got on a flat spot I took the seat off and removed the cover from the carb, pulled the vacuum piston out, then tried pulling the spring out. The last time i pulled the spring out it just fell in my hands which is normal but now it was stuck, i kept pulling on it and it finally came out. I had this same problem about 3 weeks ago but thought it fixed itself. Here is what I found, when I cut the carb spring everyone I talked to about this said it didn't matter which end i put down so I put the cut side down and this is where i made my mistake. The cut end of the spring got wedged in the bottom of the piston and would not allow the throttle to open up completely. So i put the uncut side down and put it back together. I put over 60 more miles on it and it ran flawlessly. If anyone out there has done this mod or is going to do it, I highly recommend that you DO NOT PUT THE CUT SIDE OF THE SPRING DOWN INTO THE VACUUM PISTON. It took me a little while to figure it out but i did so if this tip helps one person then this was worth writing.
