Out mowing last night, my Tiger Cat starts sputtering and losing power, then dies. It acted like it does when you run a tank out of gas, the last few cycles. But it kept running like that for about 10 seconds before it died. I'm doing all the basics: new gas, checking oil, air filter, fuel filter. After that I might pull the carb and see if it needs cleaned. I pulled the plugs, they were both carbon fouled. The left one I would say was a touch beyond normal, but the right was noticeably fouled. Engine oil was a touch low. I will have new plugs in it this afternoon after work, but wanted to see if anyone wanted to weigh in. I'm fearing the worst that maybe a ring went on the right side.
