I have a John Deere GX 345 with a 20 hp liquid cooled engine FD611V That us smoking. I pulled the exhaust off and it is puffing out if the right cylinder. It doesn't smoke till the engine starts to heat up. The oil was thinned down with gas. I changed the oil and filter, which seemed to help. Just trying to figure if it's a head gasket or valves. The mower was a freebie just wondering if it's worth saving.
