I am just getting around to cleaning and evaluating my 1919 motor. Last evening I removed the Vaporizer and the manifolds. I found crud in the #1 exhaust port. Not sure what it is. Could it be from 'critters"? What else could it be? Gaskets were in bad shape.
Thank you-Paul in Tacoma
Fluffy stuff with seed husks ==> Critters.
Pictures? hard like cement= mud-daubers!
Actually, it looks like sandy carbon or something. I guess "grainy" is the best way to describe it. Not good at pictures. And now my shop compressor is not being kind to me-leaking.
Does this always happen? Trying to do 1 thing and you need to fix 2 things before you can get back to the task at hand? Or is this just me?
Were the spark plugs in and was the head on? It could be sand or dirt of some kind. The valves are right below the spark plugs.
If it looks like grainy carbon, it probably is just that, carbon.
I would suspect oil in the combustion chamber, more that likely worn rings,
Good luck with the compressor,
I know nothing about the motor, except that it only cost me $100 a couple of years ago. I was able to turn it over with the crank, pistons look OK, head is flat and I see no cracks. No oil in the combustion chamber, but some carbon. Valves look OK, but will look at the lifters tomorrow and next look at the bottom end when I remove the inspection plate. Both the starter and the generator "motor" when hooked up to a 6v battery. They need to be cleaned up and painted. Same with the motor. Stuff will speed up as I did get all of the parts for my compressor.
