Final Entry (If anyone cares)
I gave up.
I pulled the carb again and cleaned it thoroughly; and I mean THOROUGHLY!
I cleaned all passages with carb cleaner and made sure they were clear with a thin wire.
I traced every port from an entrance to exit (except what was behind the Welch Plug, which seemed to be a wide open area)
I put everything back on the tractor and primed the carb with "Quick Start" spray.
It fired up right away and ran with the choke off.
It sounded great.
I then shut it off and reassembled the tractor to give it a try.
It still started up fine, but in a couple of minutes it started to lose rpms and lacked power.
Putting the choke on helped, but it still wasn't running well.
I tried mowing with it anyway, but it didn't seem to have much power.
I tried playing with the choke but could not get it to run well.
At one point I thought that maybe the governor was at fault, since it had trouble under load.
Maybe the governor was not opening up the throttle when the engine was being strained.
So I tried to open the throttle manually while the engine was on and the lower unit was engaged.
Before I could find it, the belt for the lower unit suddenly broke.
I took that as a bad omen and the last straw.
I did some shopping around for a new tractor and was pretty much ready to take the plunge.
Then, two days ago, I saw a fairly new used one for sale on a neighbor's lawn and ended up buying it.
In the interest of full disclosure, I should point out that last fall, while I was working on the fallen leaves,
the tractor caught fire. I had to put it out with a fire extinguisher.
This Spring I replaced a number of melted plastic parts and a lot of wiring.
The truth be told, the tractor has been running about the same as it was before the fire and I don't think it was a factor.
Thanks to everyone who responded.
This is a great forum.
I had this item posted on another forum for weeks.
There were about 100 views and NO responses.
On this forum I had several responses the same day I posted.
Thanks, again.
