Default GS11X Kyosho engine, leaking fuel

Hi, I'm new here & would like someone to "point" me in the right direction..

I'm helping a friend out with his very old car, a Kyosho McLaren F1 GTR. The engine on it is a GS11X (Kyosho), it has a new glowplug, it does start, works until it gets warm..
So, I have not been working on these type of engines for a long long time, had a Nitro car in the -80's, I do however work with motorcycles and such and know what is wrong - the gaskets.
A good thing is that the engine has not been operated much, when I was cleaning it I noticed on the piston, cylinder head & cylinder it was in a rather good condition for being so old (seen worse!).


Problem is (are):
I live in Sweden, some parts are hard to find here, even if it is second hand. I also have to travel a longer distance to get to a store that sells the parts.. It's like going from say Los Angeles to New York. Too far away.
However, I can always find the O-ring gasket elsewhere (size etc.) even have a manufacturer of O-ring that can custom build gaskets (size, diameter etc.). But I just can't find the crankcase gasket.
Can I make such gasket out of some material?If "yes", what material?

I have found a re-seller of the other gaskets and oil seals, for the engine. I was thinking that this might be good to change aswell.

The engine was cleaned (by me) in a ultrasound cleaner that I mainly use for motorcycle carburators. Also the compression feels a little "low", what is the standard compression of an engine this old?

Also, for a replacement engine, what would be a good one?

Default RE: GS11X Kyosho engine, leaking fuel

I recently restored two sandmaster buggies which both came with gt12 engines,

these engines are no longer available to buy new, same as your gs11,

while rebuilding one of my engines i saw that the chrome lining was almost completly worn off,

this caused the engine to be low on compression and to stall while it warmed up,

i looked up ebay and was able to buy a new piston and liner for £12,

as for the new gasket for the back plate,
i would just do away with the old paper gasket and replace it with some silicone instant gasket,

perhaps you could email this seller about this engine,
http://www.ebay.co.uk/itm/Rc-Nitro-C...item2a12d52194
if the piston and liner are in good condition they may be of some use to you,

Sorry for the long waight MrSaizo, yes you can make your own back case gasket using a piece of paper.
You can find most parts for your engine at WWW.INFERNOSONLY.com.
Hope this helps a bit.

Those percentages are the nitromethane content of the fuel. Most car fuels with 20% nitro will work plenty well for most people.
