Hi everyone
I have a 49 cc runabout deluxe with a 95hp K engine.
A friend helped me with a compression check and the following resulted.
Cyln.1-152 Cyln.2-150 cyln.3-142
cyln.4-142 cyln.5-150 cyln.6-155
Do these look OK?
Next we put a tablespoon of mystery oil in cylinder and checked compression again to see if rings were OK. The values were virtually the same as 1st check.
Was this correct procedure and can I assume the engine, at least for this test is in good shape?
Thanks for the forum

You should be very happy with those numbers and the best part is they're all within 10% of each other
