So it was already running, only sluggish.  I'm hesitant to use Seafoam, as I recall my father having a very expensive repair bill for one of the motors on his boat after using it.  He passed 17 years ago, so maybe it has improved since then, but it made me gun shy none the less.  WTS, the PB Blaster product I picked up has the same purpose of cleaning up the carbon deposits that may have formed on the valves and piston.  I've seen some good before and after photos from the PB product taken with borescopes, and if it works as it should on the mower I might try it on my log splitter and riding mower.

PB Blaster is a good product.  I first discovered it, after my Dad recommended it.  The mechanics in the forklift shop he works for (he's retired, but still works a few days per week to stay out of his retirement fund), they all use and swear by it.  My personal auto mechanic uses it.  In my opinion, it's one of those products that can only help, rather than cause harm.

Looks like you have been helped on that one but if anyone needs to go any further you can take the carburater (spelling) apart and
there is usually a little hole in the bottom that you can blow out with an air compressor. Always works for me to clean out the engine
at the end.

If nothing else is working, this does.
