Funny but true the way most instruction read.
Check to see if the idler is rubbing on the bottom of the tinwork. The manual says something about "Below the frame" for positioning... read it twice & then guess at what they mean...

I also noticed that the load on the engine was almost non existent while the variable lever was in a drive position but the tranny in neutral. I readjusted the carb once the engine was at full temp and I adjusted it while it was in park. She idles great now and it doesn't matter if it is in neutral by either park or gear shift. It is a shame she burns a little oil, has been doing that since I got it. Will probably try and redo the rings sometime soon unless I put a China diesel in it.
I took a quick video and will post it a little later once it is uploaded.

The vari-drive adjustment is really not hard to do but you have to do it the way they say and in the order they say or it just won't work right.

It's amazing how finicky those varidrives are, but it's also amazing how well
they work, if dialed in properly.

George, that's great! Was the idler rubbing anywhere?
It wasn't rubbing anywhere that I could see. The idler is actually a little more then a 1/4" below the frame when the vari drive is in park. When I adjusted the nut on the linkage with the tractor running and the vari drive in the 5th position there was a good bit of play between the two links (#2 and #3 in the manual diagram). I turned the adjusting nut counter clockwise with the engine running until there wasn't any play and then backed it out another 1 1/4 turns. Then I put the vari drive in the 1st position and shut the tractor down. The main drive belt was just a tad loose so I started it back up, put it back in the 5th position and turned the adjuster about a 1/2 turn in, there still wasn't any free play and enough tension on the belt that it doesn't slip in the 1st position even going up a steep grade.
