check the spark plug for corrosion, if its crusty there a pretty good chance the cylinder walls could be funky...
squirt a little engine oil/atf/penetrant down the spark plug hole...leave it for an hour or so to soak then kick/crank it with no spark plug to scrape the cylinder walls and rejuvenate the rings...
crank it a few more time to expell any excess oil out the spark plug hole before reinstalling the spark plug and continuing with fueling and spark/running servicing.
Skipping this step could cause cylinder damage and require a top end rebuild.
