My scag turf tiger is dropping a cylinder. It was the first year they made the TT, so it's 17 or 18 years old. Koehler ch25 ser no. 27..... It was popping and missing and I found a blown intake gasket wich I replaced and fixed that. I ran it that way some so that cylinder was lean and possibly overheated. Cold startup runs good, Mow for 4-5 minutes and put a heavy load on it and bogs and stalls unless I stop and turn the mower deck off. Then it smooths out and I mow 30 seconds or more and it...
