I have a couple of questions about my Wisconsin TRA-12 D. What is the best way to clean the carbon on the valves and piston? and I don't think the exhaust on the engine is right. I think it was welded or some type of quick metal used to seal around the block. Also one of the head blost was broke and is there a proper way to remove it?
Thanks
Scott

Your lucky that head bolt is sticking up that much as it will be much easier to remove. I would almost think you can get some vice grips around the bolt and get it out.

Usually to clean the carbon I use a small wire brush and just take my time. The 010 you see on the piston means it has been rebuilt to .010 oversize at some time in its life.

The muffler was definitely repaired......

Thanks Brian, I guess I could use some penitrating oil and let it sit for awhile then try some vice grips. I wish that repair didn't look so bad because I would like to have it look stock.

Mabye others may have some better advice but I did have good luck using vice grips when that happned to me. Putting some penetrating oil on is a must as well.


Yes, I think I would leave the muffler repair go beause its hard to tell how bad it was originally damaged.

I am also looking for an air breather and can't seem to find any pics of one! I would like to put this engine back to original as possible if I can.

For broken head bolt removal, if vise grips don't work. I weld a nut on the bolt, usaully the nut will just fit over the bolt. As soon as I'm done welding the nut on, I tap on the top of the nut with a small hammer. Between the heat from welding and the force of the tapping, and also letting it cool down, The broken bolt will come right out. I have had to do this 2 or 3 times, sometimes before it would come out. you can weld them up as long as you have atleast the broken bolt flush with top of block.

If you have a wire welder, I have been able to weld to broken bolts, down in the block. The weld doesn't stick to cast iron very well, so usually I can get them out that way.

Yes I've been using this method for years,it works great.I'v had people from all over bring me things to get broken bolts out of.I think in the 30 years I've been doing this,there have only been 5 to 10 bolts that I couldn't get out that way.

Same methods I use. But if you soak with penetrant, & attempt vise grips first....before you use the vise grips, lightly tap the bolt, but not enough to peen it lower or anything like that. Just light taps, and in fact, while soaking, every now & then stop by & give it a few taps. This will help the penetrant to work down the threads further. While I've never had a stuck bolt to try it on, I know quite a few who swear by heating the bolt, the taking a regular candle, or wax bar, and rubbing on the hold bolt,. They say the wax penetrates better than penetrating oil, and that bolts easily come on out.
