Took and cleaned up the ignition and on off with contact cleaner and it's been in the barn now for 5 weeks, so that's a Longshot but I'm up for checking them again, thanks

Update time, 5 weeks in and still no joy. New carb, fuel shutoff and cdi and still ain't getting spark. It's not the coil cause I took it and put it on my bosses 300 and it fired right up. Put it on mine and got power to the coil on the red wire but no spark. Friend of mine that works on small engines said it might be the igniter or something called a pulse-something or other. Theyre supposed to be inside the case behind the recoil starter. I'd complain but parts so far have only run me about $350 and I got the ride for free in great condition over a year ago. Still though I'd like figure out this spark problem, ideas?

It's got 32,000 miles it, it's my daily driver, 35-40miles a day 5 days a week. Regular oil and filter change, new coil, complete cleaning of the carb 2 1/2 months ago. Checked timing and valve lash and chain everything is ok. It just started one day out of the blue when the weather hit 98° and it only acts up when it's been humid as a gorrillas armpit or has sat in the sun all day. If it sets 20 minutes it'll fire right off and run fine

My 99 bayou 300 does the same thing except I've checked and cleaned the carb and timing and Valve lash. Sometimes it'll backfire and then run fine. If it sets in the Alabama heat it acts up but if it sets for twenty minutes with the fuel off it's fine.

Help a brother four legger out Bayou300 acts like it's flooding if it's it's in the Alabama sun all day but, I've cleaned the carb. Sometimes it'll backfire even though the timing and valve lash are in spec. Thought it was sticking float but after 2 times cleaning the carb I'm lost. So
