I have inherited quite a few old glow engines, they have been stored in a basement with pretty high humidity I was curious on what is the suggested best measure to get them back up to running speed ? I have been dropping a little bit of after run oil into them and that does seem to help but i feel the engines need more attention than that.

Also, one of the engines (Magnum .75) basically has the carb frozen shut I have been trying to soak it in oil but no luck as of now and it didn't seem like it wanted to be removed that too seems frozen to the engine housing. Thoughts?


Thanks for the help.

The heat helps melt the solids that came from the old fuel and the anti-freeze helps dissolve it's way into gunked bearings and interfaces.

With a lot of the engines that're locked up solid, pulling the backplate is worth doing. You get to see one bearing and sometimes that's a showstopper. In any case, having a more direct access to the insides helps the solvents.

I find its best to heat them up as said earler rather it be with a heat gun or my choice of putting them in the oven at 350F for 10 min. start them in it cold and let them slowly come up to temp as the over heats up. You might need to remove any orings or plastics that might be on them. At that point is when I normally break them down and order new bearings and rebuild it. Either way its a neet way to learn how to tear a engine apart and rebiuld it. Ive got 2 saito .65 that Im rebuilding now. Thats one of my passions at swap meets is to find older engines and rebuild them. Good luck and enjoy.

Heat them up and get them moving, then soak them in some glow fuel for a few days, shake them dry and use some marvel Mystery oil in them.. If you plan on using them then there are a few other things to do to get them going again but this will get them free and rolling over.
Do a search too. This was all gone over a week or two ago.

Status: offline 		Been cooking engines in a crock pot for over a decade and never had a problem with discoloration. Just make sure the entire assortment of parts are completely submerged and use the low setting. No problems using the high setting, just doesn't really speed up anything solvent wise-except boiling off all of your antifreeze so you have to replenish it more often. I once forgot a batch and it cooked for 3 days; everything was still covered/submerged and no staining when I remembered about them.

Biggest problem with staining is introducing other chemicals and cleaners into the mix. B12 Chemtool(cleaner), ajax, comet, bleach, household soaps and carb/brake cleaner residue on the engine then mixed into the antifreeze has made for intresting color and blackening acheivements for some other folks. Stay away, far away, from oven cleaners on alumium...some alloys can take it for a brief exposure and some begin to significantly pit and blacken before you even finish spraying it on.
