Older Tecumseh Snow King Engine - Valves Have Some Carbon Build-up...

I have an older snowblower with a Tecumseh SnowKing 8hp engine (22 yrs. old)

The engine runs pretty well but I get an occasional 'pop' when under heavy load... checked the valves and they appear to have some carbon build-up on them (which I suspect is causing the occasional pop).

I know that a valve soak and re-seat job would be the optimal solution, but that is a more labor-intensive job than I'd like for this old an engine.

Is there a good additive I can use that might help clean the carbon with repeated use? Any suggestions??

I went to Napa and they suggested Sea Foam (which I already have) but I wondered if anyone has a better suggestion?

Thx.

Chris

I think I would just pull the head, spray the carbon with WD40, let it sit overnite and scrape it off.
