Make sure the pipe is clear. Critters like to make homes in them when Quads sit for a long time. I got a used stock pipe from a guy that had been sitting for years. Put it on an R and it would hardly run. Found out a bunch of mice had packed it with all kinds of junk.

if you have another r swap out parts and try them but i would check for leaks in seals if it sat that long i best they are bad as well.. pull the left stator cover off and spray starting fluid behind the flywheel to the crank while its at idle if it starts to rev up that will tell you that the seal it gone on that side for sure.. aslo spray around base gasket and intake.. goodluck
if it sat for 20 years it will probably need a good rebuild.

will do i was thinking seals also just not sure i fully expect to have to do a rebuild but i was trying to see if possiable not to open the engine it has never been opened.

If pipe and air cleaner is all clean, could be the Classic CDI failure?

im with matt. Check the exhaust and make sure it is not plugged.
