RE: How to clean varnish off a glow engine?
I got around to runing the veo 1.00. It ran beter that it has ever run before. I actually dreaded runing the engine after I had taken it down to nothing. I realy thought I would have a miss. First engine I ever took all the way down by myself. I would recomend the Power Dissolver . As I said before I took the engine all apart and used the Power Dissolver on the parts inside as well as on the out side. Just don't let it set over night without oil on it![8D]

Dawn Power Dissolver
I found it in the grocery store in the special cleaning products section.
It's something that wasn't around years ago, and works. The good old days sometimes weren't so good.
A crock pot also does great. Got a new one at Target for $8.00 and I forget what the antifreeze cost.

RE: How to clean varnish off a glow engine?
Here's a tip on using Dawn power dissolver. HEAT, will cut the baked on oil goo fast!!!! I just clean my OS FS90II muffler. Put the item into a sandwich bag with Dawn Power dissolver(enough to cover the item and a little extra) Then place it into a pan(old pan or foil pan, this way if any leaks onto the anti-stick, the pan will not be trashed and the wife will not be MAD! Trust me!) Then place into the oven at 200 degF or less (her oven will go as low as 170F which is the setting I used) for 15 to 20 mins. Remove, let cool to the point which you you can handle it but still very warm. Then rinse well with warm/hot water, lube and you are done. It is EASY, QUICK and works very well with no srcubing.
Try it.
Try it.

Boil on the stove with water and dish washing powder. No bad fumes... Actually makes the house smell pretty good and won't harm the pot (nonstick). Try not to bubble over on outside of pot or the white crud may stick around for a while. Good luck.

Tried that! I am not sure if it was the type of aluminum used in the casting, or I left it too long but it turned all my bright shiney aluminum machined surfaces gray and it kept blooming white powder out of the pores.[sm=confused.gif]

RE: How to clean varnish off a glow engine?
I tried using the dawn power dissolver today, and it works great!! i have some old engines that belonged to a gentleman that I knew quite wll who has since passed away. Most of these engines are quite old, some well over 30 years, and a couple had thick layers of baked-on castor and sludge. I just put the engine in a coffe can, sprayed it liberally with dawn, and let it soak for 15-20 minutes. Then I rinse it in warm water, and dry oil the engine. They come out clean, and the machined surfaces are shiny..great stuff!!!

Please remember that antifreeze is both deadly and delicious to our animal friends. Your cat or dog, the songbirds and squirrels in your yard, will drink it if offered the opportunity. Even a small quantity is painfully terminal to them.
Most (all?) of the products mentioned are poisons that should used with care and should never be flushed down your drain.

used this type of antifreeze, green glycol, (with phosperous, as suggested) in crock pot. Used it full strength.
Engine is grey and looks like crap.
Obviously there is different chemical compositions of this antifreeze.
Unless someone can get VERY specific, chemical wise, I would avoid this technique.
Knowing the brand is no good. The chemicals in specific brands has been constantly in change for the last few years.

I've found a four inch angle grinder with a 36 grit flap wheel does a superb of removing varnish. My first experience was not so good though as I also removed the cooling fins, mounting lugs and cylinder head. It WAS clean though. In fact it looked better than new! After a little practice, I was able to refine my technique so I was only taking about half of the mentioned items off.

Im wondering if brake fluid or ATF would work better in the crock pot than the glycol. I really doubt either of those two would discolor aluminum. Whether they do a good job or not in the crock pot is another story.
Any thoughts or experience with this anyone?

Any product that is alkaline in nature will tend to darken aluminum. A neutral PH or slightly acidic would be better. Some cleaning products are buffered to clean without harmful effects.

My most recent effort was with an old Fox .59 that was so nasty it looked like it had some horrible disease. It came out of the pot looking like new.

I just noticed this is a seven year old post, but thought I would mention that if the motor is not running right, the piston/liner may be varnished up. It should be disassembled and scrubbed with Scotchbright and acetone or laquer thinner to remove the varnish. I have used the antifreeze and power dissolver method for the external varnish and they both work well, but don't seem to remove the internal varnish that comes from many hours of running with castor base fuel. I kind of prefer the Power Dissolver because I am too lazy to take the motor apart, or even off the plane sometimes. The Antifreeze is good for mufflers, gets inside better, but plastic parts need to be removed.

I just looked online for the picture to post and seen an article it has been bought out by 3M so you might not be able to find it unless it's an old auto store.

I put my parts in a heavy duty ziploc and sprayed them and sealed it.
Sounds like it has nitro methane as the special ingredient. It might be why it worked so well.

I agree totally with the Dawn Power Dissolver to clean the outside of the engine.
I just posted on cleaning the fuel tank and inside of the engine. Star Tron mixed into you glow or gas/oil mix , will clean everything out.
Every engine I put it in , run better. I had a 30 year old glow tank I took out of a plane, it had green gunk in the bottome 1/4. I put glow fuel with Star Tron in and the next day it was clean, looked much like a new fuel tank.
my 4 cycle engines are running better than every. you can use it on 2 cycle / 4 cycle. it does not hurt plastic , rubber, etc.
boat people are using it, it won't hurt Aluminum or any metal.

there is no 1 oz. small engine formula
.
Its an 8 oz bottle, one does 48 gal. and the other does 128 gal.
Its a blue bottle and the liquid is clear.
I use the 128 gal. ( both are 8 oz. in size ) I and I put 1.7 ML per gal of fuel. That's gas/oil or glow.

I use red coolant. It's the LS1 spec stuff.
This stuff is a fair bit oilier than the green coolants.
One engine went the dull dark grey colour, but that was also the first one and I let it get too hot and it boiled.
The other 8 engines came out very clean.
Can't say how it goes compared to the green stuff. Have never tried the green coolant myself.
I removed the backplates, glow plugs and mufflers. Mostly so I could drop oil onto the bearings and crankpin etc easily.
I left the engines in the crockpot for around 45 minutes a piece.
Gave them a quick scrub with a toothbrush sized plastic bristle scrubbing brush and they are good as new. The scrubbing brush I used was much stiffer than a toothbrush.
I then left them in the sun to dry out and gave them some oil.
Backplates etc were then re-attached.
