What are the bets
If I have compression of hot, 65 125 45 60 for a 1955 spread bore will it still run?

The cylinder at 125psi will run, but the others I don't know. It might run if you can spin it over fast enough. If it won't start on the electric starter, try tow starting it. If it does run, it won't have much power.

It will probably still run, but not very well. Check tappet adjustment as a first step, but most likely has burnt valves - could be rings, but one good cylinder seems to suggest this would be unlikely.

Amazingly it runs. Pour a bit of petrol into the carby a couple of times and when it starts keep the revs up till it gets some heat into it, the choke is siezed solid at the carby.
I have to run it in low range as it hasn't got enough go to run high and the lack of brakes make it a better idea anyway. The handbrake works excellent as does the gearbox and clutch. Last rego sticker was 1984.
It came from Cooma and originally had a heater and a capstan winch.
Does not blow much smoke after I gave it an oil change but fumes from the breather at times.
