Thanks Shermstake. I was going to add Marvel Mystery Oil to the oil and gas when I replace them. Any other tips? Should the spark advance level be fully retarded for starting, as in a Ford Model A?
Marvel Mystery Oil should be placed in the cylinders not in fuel or oil. It acts as a lubricant.
To start retard spark, set throttle lever to 1/2 and apply choke. Once it starts advance spark immediately. The engine will then start to run rough and then you remove choke.
I have a newly rebuilt engine and this does not fail.
Not knowing the condition of your engine good luck.
