Caught a case of the dumbass and downshifted from 4th to second and immediately after got a misfire on cyl #8, skips bad. Made it home but started mildly smoking so I cut off.

Still has 50-60% power, does not overheat, hear a slight tick but no loud knocking. It smooths out some when you rev it, ticking stays quiet.

Bad valve letting in oil?

It’s time for a compression and leak down test. That will tell what you hurt better than our guesses will.
