went for a ride Sunday and about 4 hours into the ride I let off the gas and it died. was very hard to get to start, it would rev out but as soon has I let off it died. we towed it back cause I didn't want to do any damage to it, got home cleaned the carbs thoroughly with air and cleaner hoping it was a low side jet stopped up, put it back together did the same damn thing, it also would kick back hard sometimes and backfire, that made me think the the flywheel slipped. I will check that tomorrow, just wondering if this sounds familiar to anyone.
