Hi All,
Thought I'd give you all an update on thing.
After a lots of fuss (getting the Gasket set and Inlet port O-ring), 3 evenings back I put the engine back together, leaving the cover and Flywheel Fan off just for a quick test. I had to bolt the engine down so I could tighten the Flywheel nut and start her up. So the next morning I came out, bolted the engine down but forgot to tighten the Flywheel nut!!! :ashamed: .... Engine started and promptly sheared the Flywheel key :frown:
Fitted a new key and started her up 10 seconds later there's pop, pop, pop which sounded just like the original problem but 30 second after that I noticed lots of smoke coming off of the exhaust box and the engine was getting too hot too quickly. So switched her off on the assumption that I've bent a valve or push rod. Total running time wasn't much more than a minute. Grabbed my IR Temp device and checked the temperature on both cylinders....
# Cylinder one was 44 degrees C (107.6 F)
# Cylinder two was 96 degrees C (204.8 F)!!! ... Like something has gone wrong in cylinder two!!
So I took the head of of cylinder two again and took off the springs. Couldn't find anything major except the Inlet valve has a tiny wobble (less than 0.5mm) when I spin it in an electric drill. Maybe it's a problem but can't tell without replacing it with a new one.
I'm getting ready to order parts would it be Ok to reuse the head gasket that's only been run for 1 minute?... Looks like new.
Merry Christmas!!
