The last time I ran my quad it started acting up at the end of the day. I cleaned the carb and changed the plug and it is still doing the same thing.
Here was/is the problem: The quad starts and runs (although the idle surges) and transitions pretty good through 1/2 throttle. When pinned to full throttle it acts like it is not getting any gas. If you back off the throttle a little bit the revs come back and it runs okay.
It's not jetting, because the carb has had the same jetting for 1-1/2 years before this problem arose. It used ran great. Nice low reliable idle, good tranistion and top end. It did not backfire, skip or pop anywhere in the throttle range.
I am out of ideas on what could be wrong. When I cleaned the carb I found no dirt and all of the vents/passages were clear (the best I could tell by spraying carb cleaner in them).
Please help! Any ideas are welcome.
