Is the epoxy you used able to be sanded down?

 Yes, it is called "plastic steel" and have used it before with good results. It is a slow hardening epoxy and can be shaped even after an hour. It does sag though if too much is used.

Took several hours to get the wiring sorted out. The headlight and safety switch wiring were gone. Bad key switch, headlight switch and one safety switch. The key switch plug was missing the ground terminal and wire. All new wire terminals and wire where needed. I had spare switches.

Ended up using only the gaskets and float valve from the carb kit I bought. The jets and nozzle are junk in this kit. The old parts work better than these. 

 

Checked the blow-by valve insert and it was clean but I washed it out with gasoline. When the engine is running I see blow-by going into the carb.

 

Does anyone have thoughts about using a product like Restore in this engine? I use it in my 99' Monty Carlo and it does help.

The tool tray is missing so I cut a piece of aluminum angle to take the place of it. Plenty of room to throw tools and chains into. Then I found some new trailer maker lights I had from my boating days. Looks like a good fit so I mounted and wired them into the light switch.

How bad is it? If not too bad with oil usage, Restore might help. Just don't use too much!

I don't really know yet how much oil it uses but there is not time I don't see blue smoke in the exhaust. So 1/6 of a six cylinder can be ok?

How much have you ran this engine? It might have stuck rings if you haven't ran it much.

Less than a hour total run time. Earlier in the thread I mentioned the rings may be stuck and put in some Marvel Mystery Oil along with the oil change. I am hoping that may be the problem. The engine cylinder looked good when I had the head off.

I'd give the marvel time to work. Put some in the gas also. Then run the engine through several cycles of getting heated up and cooling down. If the rings are stuck, Restore will not help!

I have some braces off of a W-Horse D series that I saved to use on fenders like yours at rear. They are not out on edge, but back in a ways, and can be bolted to that upright side tin. Has two bolts for that, and a small rubber or ? button on outer end that fender sits on. Might have two pairs, could let one go if interest?  I can put a picture on here of them if needed. I know at times you can lean into those big wide fenders and they want to give some. Have seen some bent permanently and others had split metal at the bends from that action.

Those sound like a good addition GL. Could you post a picture?

The left fender is bent down some and trying to bend it back just lifts the tractor. Your brace may hold it in place.

 

I scored a lift cylinder on Ebay for $50 total. Always good to have an extra one.

 

Added up parts and material cost so far. $255 with tires being the largest expense at $91. Good thing we do this for the enjoyment. I will never get back what it costs to buy and fix these things. :thumbs:

Hear ya on costs. Same for anything, junkie they are, more costly they become. That's why "parting" is latest thing for making money. Found braces. Thot 2, now find 3 sets. I could give up one. They don't seem to be right and left parts, both same. One will look backwards, yet should be under enuf not to show unless really looking. I put set on my "Cucumber Clunker" if you recall that one from past. Made difference. Here's pix.
