Be patient and keep trying and one day, BING!!! it will let go for you. I wouldn't take the head off just yet. The engine will still be stuck and you will have to put the head back on, A complicated process for a non mechanic. Just keep rocking it, it will break free!

Coca Cola Classic in the cylinders. My buddy busted a few flatheads with it loose. And I got a A motor spinning last week after using it. I didn't buy it but I tried it and it worked.

Wait for warm weather.

Re: Model A motor froze-up
 

Sounds like you are on the right track. Persistence and patience will pay off. We would love to see pictures of your Model A! I lived in Grand Forks, ND for seven years while attending UND and flight instructing and did a lot of cross country flights out near Devils Lake and your neck of the woods. I know of a couple other Model A'ers on the fordbarn from Nodak that might be able to give you a hand also. Good luck!

Re: Model A motor froze-up
 

Thank you, Terry, for the hope in my grueling effort.

Re: Model A motor froze-up
 

Thank you, fordman. My aim is to see Betsy up and running one day. She's been idle a long time. I've neglected my prized old friend for too long. Now's her time. With all the suggestions I've been receiving even these dish-pan hands will see her going again. Thanks to all the interest and expert advice, we'll get her going.

Ha! George Miller.
It is in the 90s here in ND. I'd hate to see it get much warmer~with a smile.

Re: Model A motor froze-up
 

Sorry Bill Williamson,
I must have missed your suggestion to "fill up to overflowing."
Last fall I did put about a pint of diesel fuel into the 4 spark plug holes. I left it over the winter expecting results this spring. No such luck. Since then, in my discouragement, I've left Betsy until now. I'm back with determination to get that motor loosed. My present task has me using Marvel's Miracle Oil. I have poured 2 quarts of it into the 4 spark plug holes, set the gear to high, rock Betsy back and forth with gusto. The crank handle moves slightly, but no "break-through" yet. I'll keep trying.

Re: Model A motor froze-up
 

Yo, Betsy, My ooold Remington, Model 41, Targetmaster .22 squirrel gun is named BETSY too! Anyhow, When Chief & I built my first Model A, a '28 CCPU, we were given an oooold portable arc welder, powered by an "A" motor that had been sitting for EONS! We kept it filled to overflowing with diesel for weeks & was finally able to turn it. The motor was mounted quite high & we were able to get the pan off easily. We disassembled it in place & the babbitt was excellent! After lapping the valves, honed & re-ringed the pistons, we used the rig as a test stand & ran that dude with a homemade garden hose cooling system. Chief said something about it being a REALLY EARLY engine???
It turned out to be a really good engine and in it's lifetime, I used it in 3 different Model A's.
(OH! Chief was my Dad & Model A mentor & I quote him often. He "built" dependable "A" Models in his spare time & sold them, so we could EAT!!) Bill W.

Re: Model A motor froze-up
 

A couple of important questions! Does the crank handle move? How about the fan? (Someone watches while the other rocks) It sounds like you're well on the way. Did you check the oil level in the crankcase? Has any of the Marvel's Mystery Oil leaked down through the rings and into a crankcase? You should have six to seven quarts in the CC now. That's good too!
Terry (Just keep rockin")

Re: Model A motor froze-up
 

I posted something similar a year or so ago and it wasn't received kindly.

I don't see why you should get preferential treatment! LOL

Re: Model A motor froze-up
 

Wished I'd had a "Chief" to give me pointers today. When my Dad worked on Betsy, I paid no attention. My loss. I wasn't interested then.

I added more Marvel's Miracle Oil today, rocked some more, will try again. The crank moves only a little. The fan moves slightly with it.

Will keep rockin.

My husband likes to tinker too, but he's guessing right along with me.

Re: Model A motor froze-up
 

Thanks, Charlie. I'm taking it slow and easy. The crank is quite solid, won't force anything.

Re: Model A motor froze-up
 

How do I "drain the crankcase?"

Re: Model A motor froze-up
 

That's FUNNY, Ross, You're about as INSECURE as me!!
Chief used to say, "We're ALL insecure & need attention & sympathy,:( it's just that some won't admit it"!! Bill W.

Re: Model A motor froze-up
 

Keep her rocking. Soon you will see movement growing exponentially. First 1/100th of a revolution then 1/75th then 1/25th and on and on. Sounds like it will free up!

Again, leave the plugs out of it until it spins freely with the starter.

Re: Model A motor froze-up
 

Personally I'd forgo the MMO for now and use 50/50 ...ATF/acetone. It's a thinner solution that I think penetrates quicker and a proven "unsticker". I have a formally "stuck" A engine that I unstuck. I put a 3/4 inch drive, 1 7/16 socket on the crank pully (engine was on the ground) with a breaker bar and nudged it every day til it moved. 1/8 inch, 1/4 inch 1/2 inch ect. doesn't take long once you get a little movement going. It worked for me. Good luck!

Re: Model A motor froze-up
 

Thanks, Rusty.
Wished I'd gone the 50/50 before I did the MMO.
Now, if I can figure out how to drain out all that MMO . . .
I'm going to keep trying any "unsticker" that will possibly work.

Re: Model A motor froze-up
 

Ok, Ross.
