Thanks Jack, pretty sure this motor would be the 141300 series, would you risk a guess at year of manufacture?
Thanks AVB, I had a lot of trouble with the key, I have just used a piece of 3/16' key steel with a lot of filing. May not have had this problem if I put that much effort into it first time around. I probably only have around 20 ft-lbs on the clutch so I will give it a little more tomorrow. Reluctant to go all the way to 50 with the tools I have as the clutch would be easy to break. I could take it off and try to find a nut with the same thread.
The good news is that if you put a little fuel down the plug hole it runs, (surprisingly quite smoothly) for two or three seconds. The bad news is that that is it, no amount of cranking gets any more running, so I think I currently have the electrics right, and the current problem is with the carburettor.
If you think the nozzle I have is the correct one, and fits all the way into the carburettor throat I will try to work out a way to get it to seal.
I am back too 100 psi compression. The head gasket is in fairly ordinary condition so I gave it a spray with a product called Hylomar, I have had it for about 25 years but had good results with it on an old outboard motor with a warped block. Probably temporary but it would explain why I originally got 100psi and then only 75. Do you know what head bolt tension is likely to be?
Regards Randy
