so finally got the quad started after the winter, I use a 1987 LT-4WD on my ground for "yard work", today after a very hard start, the choke cable snapped, fixed that (temp), got it running, idle is rough. added some seafoam to the gas to help clean it up.
Hooked up lawn aerator loaded with cynderblocks and the quad would not go. seemed like it was trying, but nothing. reverse worked fine. hi, low, 4wd, no difference. anything forward was no joy.
So, the engine lacks power. pulled the sleds fine over the winter - and before that, now is the only time she wont budge!
