i unfroze my RC plane nitro engine using your method but using WD40 and it worked like a charm. TY

[@adr8nalin73]

By far the best explanation, thank you sir

[@thatracer05]

Thanks for this! Huge help. Worked like a charm. Hoping my truck starts today!

[@GottaKnowJoeHobbies]

Glad it helped

[@officialelysium4821]

Thanks this helped me with my tmaxx 3.3

[@biogons14]

This method has worked for me with a Super Tiger engine from the 70s. Instead of fuel I used isopropyl alcohol, and light oil when was unseized. But, taking many precautions; open window, gloves, protective glasses and mask. Very thanks.

[@GottaKnowJoeHobbies]

I'll need to try that

[@letusshare5316]

Thanks for the useful tip.

[@dmrcflyr2]

3-in-1 oil works every bit as good, is more readily available than glow fuel, AND cleans any rust that might be on any steel parts. It is MUCH less expensive than hobby after run oil. I always use oil and heat to loosen a gummed up engine, but I NEVER use a vise to hold an engine. Heat resistant gloves and a prop installed on the engine is all that is necessary to turn it over.

[@GottaKnowJoeHobbies]

Great point!

[@savagenoob]

Clamping the engine in a vise where he did will do absolutely no harm to it. That's where its mounted to the chassis and is designed to hold the engine in place.

[@GottaKnowJoeHobbies]

Nitro should be readly available if you own nitro engines I'd guess. The 3n1 did not cut the gum as well imo..but my technique may be wrong

[@RC-Flight]

Dave thanks for calling this engine and fuel glow, it’s not a nitro engine or nitro fuel is it!

Yeah that marvel mystery oil is a miracle this old dude would put it on and in his motors and tools and yeah it's amazing shit specially when you let it soak in over night a nut you can get out or bolt off next day that bolt or nut will come out like butter

MARVEL MYSTERY OIL I speak as well as a drunk worm with itchy feet... ?? Lol, I don't know what this means either it just came o me.

[@bryanmillers3231]

Thx I just did it to my taxxax and it worked perfectly I just used 3 in 1 oil and a heat gun

I'll need.to try 3n1

[@mdrc3288]

Great technic!!!Never thought that this could be possible without removing the head!!!🙂👌⭐⭐⭐⭐⭐

[@ashermorales8276]

I had an old novarossi .12 and the bearings and the crankshaft were super gummed up. I took the thing apart, popped out the crankshaft and used a tooth brush and some break cleaner to scrub off all the gummed up oil and completely cleaned out the bearings. I didn’t worry too much about the piston sleeve and rod because I had a spare set that was brand new. Once it was all clean I heavily oiled everything with 3-in-1 and it was basically brand new

[@GottaKnowJoeHobbies]

Always good to wash out the bearings with solvent add oil until smooth and free

[@GottaKnowJoeHobbies]

I've used s lot of stuff never brake fluid. Probably cause u hate the smell and fell of the stuff and I seem to always get it on my lip and taste it for 2 days after. Lol but I will try it once .. brake fluid eats the hell out of paint that's for sure. This method is really used more to get the. Unseazed so you can tear em down . Ill need to do a more detailed video on a full clean.. and rebuild. If its cool I may use your idea as well To see how it works..im very interested in trying it now.. I could relax if I wasn't so curious lol

[@tenlittleindians]

@@GottaKnowJoeHobbies He didn't use brake fluid he used brake cleaner. I'm curious too if it will cut old dried up castor oil. Carb cleaner should be safe as most model motors and carbs are aluminum. Again; I have no idea how effective it is against old castor oil. The old timers used to recommend putting the motors in an old pan of antifreeze and heating it up on a stove to clean them.

[@brucerumrey8894]

Great video that what I do

[@stephenparkins3552]

I do this quit often with engines I get on craigslist. I use mystery oil, soak the cylinder and the carb over night. Then I use my heat gun. Get it good and hot and it will break free every time!

[@williambryant6654]

Marvel mystery oil ,great stuff for after run and storage.

[@d.haroldangel241]

GLOW ENGINES is the name. They are not all necessarily run with nitro(methane). It's called GLOW FUEL (sometimes containing different nitromethane percentages.

Enjoyed your video very much. Question: is there a fire risk with the heatgun? This is a diy heatgun, not a hairfohn right? Tnx 👍😊

[@GottaKnowJoeHobbies]

Yep. it could sir... but. I've been doing it for years and common sense or lack of it, has kept all my fingers attached..6 right? he mutters and counts under his breath slowly "7,8,9,....no 10 I'm sorry"... lol .... sparks are not desired.. we just want to warm the cases... Don't use open flames Ya Gotta remember, NO LEAD in Soldering wire works poorly, The "NEW Safer" glues don't stick well, and Wd40 will not cure aching bones since the DMSO was removed. POINT IS if it's "safe" or Safer" or better for you .... things that seem to taste bad. or fun is not as fun, worked well. now don't work, or is now illegal ;) ( I must write this is a parody so as not to hurt anyone's feelings that do not understand the pun.) Please, folks... I do not want to enter a BIG controversy about this. it works for me and has worked for many. If you are dangerous with an ice cube, hammer, or spool of thread it may not be for you,,, lol Bert this is not directed to you brother. I can just see it coming though.. lol trying to get in front. Your question is valid And yes It could... but my highly uneducated non-existent field testing has proven, chances are slim to none but everything is possible. Hope it helps

Marvel Mystery oil all auto shops have it Glad this helped .. call us if you ever need a hand ... or a deal

[@davidpalacios1017]

Hey joe, I have a question you may be able to answer. I bought a new Kyosho and the engine seized on the first idle, I unseized it with a heat gun and it locked up again on idle. When I purchased the buggy it was very hard to pull the starter without unscrewing the glow plug. I unseized it and added mystery oil now. Question is any idea why it locks up when the engine gets warm?

[@GottaKnowJoeHobbies]

Could be something up...but it should turn freely with no plug. And bir of resistance on TDC top dead center during to the squish. The narrowing of the sleeve .. you may be running too little oil also. I would reach out to manufacturer and or take it to a shop so they can look over all the possibilities before you fry the engine

[@GottaKnowJoeHobbies]

I wish I had the definitive answer I just don't think there is one

[@cornpopfan319]

My engine will rotate half way and then compress and stick while the plug is in. If I take it off, it’ll turn over. I’m new to glow engines so is there something I’m doing wrong here? I’ve already primed it and put the igniter on a brand new plug, but the issue still persists.

[@GottaKnowJoeHobbies]

There is a thing called vapor lock. You've got to watch out for. That's when you get fluid and door gases on top of the piston, which hydraulically it combust a piston. Besides that, you want it to turn freely with the plug out. But when the plug is in, that's your compression that makes your engine run

[@cornpopfan319]

@@GottaKnowJoeHobbies thank you so much. I cleaned and sanded the cylinder thoroughly and the underside of the piston, re-oiled everything and then got new fuel lines. It started for about 2 seconds and now it just hisses and sputters. Definitely some progress

[@Workerbee-zy5nx]

Wd 40 also works

[@dynevor6327]

Just "freed up" 7 engines 2 and 4 stroke using WD40. Engines had not been used since the mid '80s and all came free immediately. The hardest part was removing the barrel from the carbys. One 4 stroke took a little time to free the cam followers but slow and steady.

What if you put the nitro in an old pan heated up on the stove - then let it soak for a while ?

[@GottaKnowJoeHobbies]

We do it as well on real bad ones but you must remove all the plastic and orings 1st..becareful of plastic carbs

[@FindShindoHere]

[@GottaKnowJoeHobbies]

But don't heat up the fuel in a pan NEVER get around open flames. OLD into will blow. We stay below flash point and no flames with gun

[@afshinpishehvar7815]

When we buy an old nitro engine, how do we know if it works clockwise or counterclockwise?

[@GottaKnowJoeHobbies]

Car or plane

[@GottaKnowJoeHobbies]

Most all engines turn counter clockwise if you run into a clockwise turning engine it's rare. Fe 350 kawasaki turn clockwise and it cost me a tine of cash youbjust do see them so you don't need to look for them really

[@craigwilliamson4345]

Just as easy to pop it in a boiling pan of water for 15 minutes

[@tbd-1]

Just did this to an OS 40 SF. Once the water boiled I took the pan off the stove and dropped the (complete) motor in the water. After a couple minutes I drained the water, wrapped a towel around the motor and broke it loose with a pair of channel locks on the thrust washer. It offered little resistance and the whole process took less than 10 minutes. A good flushing out with WD and MMO and it's ready to bench test.

[@tobydyes]

Does that work for all nitro motors or just airplanes

Yeah, let’s poor methanol, nitro and oil all over the place and then add a source of ignition to the mix, makes perfect sense to me. Heat and oil, NO FUEL !!! This is a terrible idea, don’t do this unless you’re ready for the burn ward. Be careful what you glean from someone who’s been doing something for years and never had anything bad happen, YET ! No, don’t do this.
