I thought the engine was out of the car. That's the first thing I would do. It'll be so much easier in the long run.

Stripped of it's head and flywheel, the model A engine is surprisingly light. I support off the aft end of the block in my engines. Many model A engines have been used in Pietenpol homebuilt aircraft.

As usual the experts are correct. I misspoke earlier - I was thinking back several years ago, and I now remember I did have to ream the small ridge off the top of the cylinders and pop the pistons out the top. Stand corrected.

No,...it's not carbon! It's a ridge, made by the rings....due to wear in the cylinder.
You need a "ridge reamer" to remove the ridge,....then the pistons will
come out easily...

Well I have been soaking this last stuck piston since I last posted. I finally tried Evaporust for about two weeks and a floor jack pushing up from below. Would still not move. I tryed the last resort, using a brass drift and hammer. I hit it from above and it moved! Crawled underneath and hit it again it moved! Tapping with the drift and hammer it came out. Fighting me all the way. The piston didn't break or get marred up but boy it sure is ugly. Now I'm gonna hone the cylinder and see how it cleans up. I think this deserves a nice cool one!

Hey, Dubnutty!
I love to see newer interest in the Model A! Please pay attention to some of the great advice on the Ford Barn. After a while, You'll see who knows their sh..! I am a relative newbee here, and I've gotten the best advice from the SOLID hobbyists. Like me, they are TRUE MODEL A AFFiXIONADOS. You will spot them if you are of the same ilk. Listen to these guys. Some are mechanics, some are just Model A Lovers like me. Avoid the sarcasm, and listen to the experts. They are getting rarer and harder to find.
Let's duplicate ourselves. Get the youth involved in our sport/hobby. ~Chuck

Got some free time to work on the wagon. Took the pistons, oil pan, dipper tray, valve chamber cover and drain tube to work and stuck them in a part washer. I wish I had one of these at home! Parts cleaned up real nice. Some of the paint came off so nothing but clean metal now. Removed the intake and exhaust manifold and bead blasted the intake manifold to prep for paint. I disassembled the carb and soaked it in Evaporust, wow this stuff does work, and also ran it in a ultrasonic cleaner that I picked up at Harbor Freight. I was suprised it worked real well. Still has some rust and varnish build up in float bowel. I'm thinking of bead blasting it but I'm not sure yet. Next I'm going to clean the carbon build up on the pistons and rings. I'm think of blasting them with walnut shells and see what I can remove. Well thought I'd give an update and maybe post some pics later. I forgot to take pictures of the carb before cleaning started.

Didn't you say you used a hammer and brass punch to remove #4 piston?
I would be very leery about using the piston. And I know what damage a big hammer can do

Yes, as Ray said, that's a 30-1 radiator with a replacement honeycomb core. The 1928-9 radiator neck has external threads for the screw on cap. The 28-9 is also not as tall as this one.

Ok, back on it and found some bad things. That piston that was stuck has got a big crack on skirt. 
Well the plan was to just get this motor running enough to get the car moved around. While I went through all the mechanicals. Where do any of you send your motor out? Who do you trust? I'd like a touring motor done. Modern bearings and updated valves. I was hoping at least to get the motor running to see if it had a cracked water jacket or cylinder. Any help here should would help.
