Ooooooooooh Darnnnnnn!!! Started the 45 this morning after oiling shafts and WD40 to blade faces, and I guess my fault because I dont have the choke lever, the governor may not be working when choked, so it reved up a but higher than normal for a few seconds under (manual) choke and BANG!!! Now no compression whatsoever when you pull the winder - crankshaft just runs on with no load against it.

You experts out there - what is likely to be the problem? If the main bearing or its housing had broken I would have though the c/shaft may have jammed or given some metal noises. Similar if the piston compression ring had gone. What about valves? Maybe not closing? Not sure the design of these valves and how they work.

Could the cranshaft key have broken? But would that just affect spark timing not the valve openning/closing? (CLUE: recently on stopping the engine has given one "POP" back fire at the end).

WHERE TO START?

Suggestions PLEASE fellow Scotty's with B&S engines???
