New AND correct head gasket on, complete with a slathering of Copper Coat for good measure, thanks to our good friends at Steiners. Still a couple of things to iron out with the transmission- I can't get it to shift, and even while practically standing on the clutch it will inch forward a little. Almost like it's trying to take off and I have to get on the brake a little. Im stumped once again, which isn't saying much.

Feel free to chime in if anyone has any ideas. And thanks to so many of you who've commented, offered advice and encouragement, and words of wisdom.

You had a long clutch thread going before you got sidetracked on the head gasket.

I never saw what looked like a wrap up on that discussion. Your current problem is probably mixed into it. What happened when you took the pressure plate in for rework? Did you readjust the fingers (or have the shop do it)? Did you clean the rust off the splines on the clutch shaft? How about adjusting the free play after it was all assembled?

I got the pressure plate back from the shop and he said that it was already adjusted and ready to put in, so I did nothing. I didn't adjust anything after I put it all together, but I believe something is put of Keller, somewhere.

I believe I'm going to take the shifting rails apart and see what's going on with that, because it should not be that hard to shift into gear. I can take the top cover and shifter off and move the gears freely and they all spin, but the second I put the cover on, then BAM! instant shut
down in the shifting department. So, we're back to baby steps and trying one thing at a time to get things working. I appreciate your input and advice and am open to suggestions in the clutch and adjustment matter. Heck, I'm open to suggestions on just about anything! Thanks a million.

On the matter of adjusting the free play once the clutch is installed, is there a procedure somewhere that will explain how to do this?

Free play at the face of the clutch pedal should be about 1-1/4". You adjust it by reaching into the bottom rear of the bell housing and turning a pair of nuts. It should be explained in the Owner's Manual. If you don't have that manual, go to the PDF manuals. If no manual for the B, look in the Cub etc. PM Manual. The explanation in there for the 140 is the same.

does the transmission shift through the gears with engine off? if so then you have a clutch issue

Yes, it will shift through all gears off and on. I just drove it about a half a mile down the road and back and even with the clutch pushed all the way in I had to force it I to gear and then back into neutral.

so the clutch is the issue, it is not releasing so it can be shifted, check finger height, pedal free play

Just as a follow up, I wanted to go over what I did with the shifting rails and gear shifter for future reference.

I took the entire cover plate, rails, and shifter off and disassembled everything then sprayed everything out with brake cleaner. Then I used mineral spirits in my induction sprayer with 120lbs of air and cleaned grease and 70 years worth of build up out. The three springs and ball bearings all came out and those ports got sprayed and washed and scrubbed out with a small brush. I learned that one of the springs is longer than the other two and it goes in the center hole (the triangle of holes is plain once you open it up if you haven't yet) and it began shifting better after that. Once everything was apart, I sprayed the rails down with the mineral spirits and brushed out the dirt and oil and grease, etc.

I still have the clutch matter to deal with tomorrow and will adjust that as soon as I have some time and try to get that fixed so the shifting issue is done and tended to.

Thanks to all who've commented and offered suggestions and advice. Y'all are lifesavers.
