if its blowing from the carb its losing compressionYeah windy miller there is decent compression

all engines have to have a way of relieving crankcase pressure caused by the piston movingIt seems to blow out of the sump cap too, there are holes in the oil filler cap which i thought might be acting as some form of crankcase breather??

not when its blowing back through the carbWell that probably rules out a valve clearance/seating issue then. Try the easy start thing. If there's compression, and it's sparking at the right moment it shoud at least cough a little. If it does, then I'd be inclined to think it's carb related - probably a blocked jet. If it still shows no sign life, it's probably ignition related. These engines are so simple, there's very little to go wrong!
id remove the head check the valve clearances popular valve clearances are 8 thou inlet and 10 exhaust if all is well there and not opening twice or staying open due to seat wear give them both a regrind and try againAnd wen head is off the valves go up and down nicely.... So its not like one is stuck...
Yeah but windy miller, i have tipped a little fuel into the plug hole and i still get nothing...wen i try normally the plug stays bone dry...

id say valve & compression trouble if he has a spark and its timed correctly has poured fuel in with no effect it can only leave compressionI'm not convinced about the compression if it's blowing back through the carb. Surely one or the other?
as long as the key is intact then it will be fine like most of these old simple enginesThey dont really have timing as such... Just a flywheel key

you only need a small amount ive always had success with that method just a small amount down the plug hole wait a few seconds for some to evaporate and give it a goTbh I've never had much success pouring fuel straight in. Brake cleaner works well, and so does Easy start. I've always though that pouring the fuel in is the same as when the engine gets flooded. All fuel and no air!

not even a thimble full half should be okWell that's encouraging! Next time I get an old engine I'll give it a try! Roughly how much petrol do you throw in? A thimble full! Table spoon?
