How To Free Up A Gummed Glow Engine

A quick video to show how to free up a gummed glow engine. This wont free up a rusted seized or heat seized engine, only an engine that's stuck solid from oil that's gummed up over time.
This engine is an MDS 40, a notoriously bad engine due to a badly designed carb i suspect. They did make a version 2 carb which made them run better apparently but the 'mostly dead stick' 'mine doesn't start' 'metal door stop' nicknames this engine carries in the modelling community says it all!
Im going to heat seize this engine by under propping it, then im going to free it up only to rust seize it, then free it up once more to kill it once and for all in a spectacular fashion.

I used nail polish remover and 15% nitro fuel and it worked perfectly lol

I use a micro torch to the cooling fans for a few seconds at a time and it loosens up the old castor oil so you can turn engine over. Use synthetic now so I never have that problem.

I have some MDS 61 with rear exhaust. The engine is very powerful ,but the bearings and the carburetor are shit. I replaced the bearings against good quality c3 bearings,and use a Webra Dynamix carburetor. It runs on a Speed plane like hell(over 21000rpm)with reso exhaust and 20percent castor/5percent nitromethan/75percent methanol.After flying i use automatic transmission fluid as after Run oil. So the engine never gummed Up. I make this with all my model engines,which runs with castor Oil, since 40 jears. My abc engines runs only for breaking in with castor oil. After 2 hours i change to full synthetik oil. Blend of castor and synthetik oil is crap. I use Motul Micro 2t oil. Greetings from Germany

Prior to store a nitro engine i open the carb full with removed glow plug and pour in a 2stroke motorcycle oil and crank with starter until oil will come out on the glow plug hole

I don’t know if you will respond or not, but will it seize back up when it cools down?

[@bryanmillers3231]

No I just did it today one all the old gummed up gas is broken down it’s done it’ll only seize back up if u let it sit up and not used again

[@irishlad7458]

I about to clean mine been soaking it in vinigar had some rust on crank and 1 way bearing I only run it in 18 years ago in a thunder tiger mine is only gunged on crank all rust gone now will soaking it in methanol desolve castor oil

[@johnsaylock5095]

Are all MDS engines crappy?

[@user3141592635]

Cook them in Propylene-Glycol or DOT-4 Brake-Liquid at 120°C for a couple of hours to begin with.

Add some potassium permagnate and you’ll be running a hot engine.
