I have a '73 CB350 with a frozen engine. It was running a few months ago. How should I go about trying to unfreeze it? What causes it to be frozen in the first place? It hasn't been outside at all.

I just looked at the plugs (It still wouldn't turn over with them out) They look like they are carbon fouled (black charcoalish). Any idea if that would have something to do with it? I'm going to try the oil soak/rock back and forth and see if that will help.

ouch!
is it still froze up if you remove the spark plugs and try to turn it over? its possible that after sitting for so long fuel may have seeped into the cylinder and you're getting a hydrualic lock. if you can turn it over with the spark plugs out do it several times to get all the fuel out. then replace the plugs after cleaning them and put fresh fuel in it and give it a shot.
if it is still locked up with the plugs out---i'd look at the plugs and see how they look--they may give you some indication of what's going on.
is your battery charged?
i don't know why it would lock up from just sitting for a few months. have you had any kind of trouble with it like this before?
i had a honda dirtbike lock up on me once because the goofy mechanics at my local honda shop filled all the oil passges with permatex---i burned the damn engine up---being just a silly kid and not knowing any better.
best of luck!

The only time I ever froze an engine, it was for lack of oil. Cost a new engine. Hopefully, yours is just condensation turned to rust. You'll still have to take the heads off, shoot some liquid wrench or equivalent into it, and knock on the pistons with a hammer and a block of wood. Be careful! You might be better off just rebuilding it from scratch, though.

Take out the spark plug and pour 2 cycle oil in it and full and let it soak to see if that unfreezes it up.

Oil in the cylinders, let it just sit for a couple of days. Pu it in 2nd or 3rd gear and rock it back and forth. A couple months really should not be a problem.

relies upon on industry and criminal definitions, licensing regulations. eu industry has a wreck at 125cc for criminal 'mild' type', US industry the wreck is at 150cc- 'mild' cycles no longer allowed on interstate gadget if decrease than 150cc, federal 'motor pushed cycle 'type' . Middleweight type is defined in some coverage tables as as much as 500cc, some states regulations on the subject of coverage standards have the 500cc wreck, some had 500 cc as a graduated license type some years lower back however the states with graduate license like California and Illinois are utilising 150cc wreck specifically. A older well-known grew to become into 250cc and 15 horsepower as wreck for 'small' to 'medium' which went to 660cc to get the main user-friendly on the time 650s leaving the 750 to 1300 cc because of the fact the 'super/vast length that could have had coverage fee extra suitable. those have been industry, criminal, coverage definitions utilized in united states of america at distinctive markets. Germany had coverage type breaks with the help of engine power besides as engine length- get a 100hp 750cc and you will pay plenty extra for coverage than a basically decrease than 50hp engine- Harley 883, BMW 650, Honda 400cc. 'vast and small engine' exterior of a criminal, commerce, coverage, or motor vehicle plate definition varies with the help of the guy and industry-- Australia breaks at medium 660cc, India has 125cc breaks like maximum eu user-friendly industry international locations and US has a 150cc 'mild/small' wreck.

Sounds like the engine got hot or ran out of oil, could have scored the pistons & cylinder walls causing it to freeze up.

Remove the spark plugs, squirt Marvel Mystery Oil into the cylinders and let it soak for a day.
It will turn over . . . it may even start . . .but it won't be pretty.
Make sure you're outdoors.

if it ran out of oil it is most likely the reason it froze up,, remove the engine from the motorcycle and tear down if you are mechanically adept if not let a qualified mechanic look it over.. it will cheaper then makin a costly mistake
