Tq!you save my day..2 of my rc engine now works well.thank you again.greetings from Malaysia!

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

Thanks you ! the heat gun worked out great!! Unstuck 3 engines

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 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

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

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

Pozz imam dva motora Enya29 iEnya 09 ..pa me zanima kako se to upali

Are all MDS engines crappy?

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

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

MDS (Moscow dog shit) we always called them. Total shit engines.
