In trying to get my cub engine to free up I pulled spark plugs and poured ATF into the plug holes. When I did this the fluid poured out of the carb. Wondering if Iam doing something wrong? Seems the oil would have troulbe getting down to the cylinders? I could look in and not see the fluid staying in their. Could someone explain the correct process to soak it. Also how much fluid should be poured in and how often?

Might just be stuck valves. They lock engines up to when stuck.

Now if it was me i would just have to pull the head and see why it is stuck as it being a cubby with a flat head and for the price of a head gskt. I wouldnot waiste my time tryen all the old wifestail methiods . I have said this before and i will say it again best stuff i have found bar none is Zep's penatrating fluid hard to find but worth the hunt. Pop that head off get some Zep a littel spray here and a littel tap there will solve the problem if it is not total rust like the one cub i ended up withthat the man said was only lightly stuck , yea wright could not tell were the pistons ended and the bore started . That one went to the dead row may have ended up being a Toyota .

Guess what your doing it the right way. Most likely the cylinder with and open valve still has enough tranny fluid sitting on top of it to do the job it needs to do. If your worried about it then just take a hose clamp and some thing and cover the carb up and fill the cylinders more since the ATF will not hurt the carb any shoot it will probably help it in the long run

the cub has the c-60 motor in it. it does not run sleeves. also, the valves are in the block, not the head. the reason the trans fluid came out the carb is because one of the intake valves are open. lot of guys here use trans fluid and have good luck with it, others have their special home brews. use whatever works.how long has the tractor been sitting since it ran last? if you bought it stuck, i would pull the cylinder head and oil pan and see whats up in there. the super m i am woking on now sat for close to 20 years in a barn, stuck good. as i am overhauling it anyway, first thing i did was drain the engine oil, and fill the block with kerosene and let it set for a month. drained it out, filled the cylinders with pb blaster, let it set a couple weeks. between rocking the tractor by hand in 5th gear and bumping the starter, it broke loose. then it was a lot easier to disassemble. its your call how you want to proceed, if you break it loose, it may run good. my luck it would toss a rod out the side of the block first time it fired up.

You're getting fluid in the carb because you've got an intake valve open somewhere along the line. Nothing out of order with that.

If the fluid is draining down out of all the cylinders, that would suggest stuck but broken rings. It can drain through the gaps in the broken rings, but those rings are still bonded tightly enough to the cylinder walls to bind you up.

ATF works when it has a chance to soak. If it is draining out that quickly, you're not gonna make much progress by pouring more in.

You may have to bite the bullet and at least pull the head for a looksee or (more likely -- sorry!)pull the whole engine and break her loose and clean her up.

well...it shows your valves are open! the ATF is running back down and out through the intake...no biggie, just keep adding...watch and see if it runs out when you pour in a certain cylinder...if it runs out immediately....that piston is at TDC or close and the intake valve is open...move to the next one and add more...it shouldn't run out so soon. Nothing is wrong so to speak..just where the pistons are sitting in the cylinders. old says it 'takes what it takes' for the ATF to work.

Once upon a time, I had a JD 430 that was stuck and stuck hard. I finally pulled the head and took a wood block and put it on top of the piston and whacked it with a sledge hammer until it broke loose. I tried everything else I knew and felt I had nothing to lose....it either had to move or come out...in pieces if need be. But, all was well..it broke free. I honed the cylinders a bit, put everything back together and it ran fine. Your mileage may vary.
