and this is what I found. It has the pressed steel mag, has had bronze valve guides, and has .031 OS cast iron pistons. The pistons are tight with no slop but I haven't measured yet. A standard valve still fits the guides but they are beat down in the block. Had a fiber timing gear with teeth missing. This weekend gonna do some plastigauging and check things close. That is the plan anyway. I tried to get some pictures posted but I couldn't get them small enough.

Maybe it just needs a timing gear and some valves with oversized heads? You can buy Fordson tractor valves with 5/16" stem and 1.66" diameter. Then all you would need to do is cut the seats to repair the sunken valve condition.

You might even get a slight boost in compression by using oversized valves. Takes up a bit of space in the chamber. Good idea. No matter what else you find that gear was going to leave you flat pronto.

Don,what size are the valve stems?
If they are inserts,you can remove them by taping them with a thread tap and then use a washer and a long bolt with a nut on it.It would be better to use a tool like is in the kit for small engine work that is shaped to fit the valve seat.But once you thread the bolt in,and use the nut to pull out the insert,you can knock a new 1 back in.
I dont have the tool but I have had guides in other engines Knurled.it is a tool that puts grooves in the guide that expands it.
Wont last as long as a new guide though.

Mag bolts should be peened to flywheel and they look like they are wired with copper--not sure that is a good idea.

First time I have ever seen that too. I'm thinking I'm going to do it a little different. But on the other hand it's been that way a lot of miles.

Don-
If you take the transmission off, look for a date on the end of the transmission flange.

This one is Jem's. 8-16-09.

The early ones had brass wire through the screws.
