Gasket Sealer

[twentysix by twentyfive]

Hello knowledgeable folks.

I think the gasket between the carburettor and the cylinder block on my two stroke engine may be leaking. That bit gets fairly hot. I don't think I can source a new gasket as the engine is no longer "supported". So does anyone have a recommended hot gasket sealer for this situation?

TIA

What's the engine?

What's the engine?

It's a chainsaw one. Jonsered CS2137 Not sure how I can extract engine details from that.

I've just been googling and gaskets are available for the CS2137 but before I spend even more dosh on this thing I'd like to do a cheap sealant type job first to see if that solves the problem.

Red coloured JTV rings a bell,?

I don't know if you can still get gasket paper but I imagine you can. Just a case of making a template on a piece of paper and transfering it to the gasket paper cutting it out with a steady hand and a sharp craft knife.

Looking online, the OEM part looks like a composite gasket, so it's probably worth replacing it with a new one. The gasket shape looks quite complex to replace with a silicon sealant or jointing compound without making a mess.

Plain cardboard gasket smeared with grease would do the job.
Cut one out of a Cornflake packet.

Do you think he could get away with a Rice Crispie packet gasket?

Even better. It will restore the snap, crackle and pop to his 2 stroke.

This should do it for a fiver from Euro Cat Parts:

We used to use Hylomar for gasket seal, and use a small ball peen hammer to cut most gaskets out.

Used to be £45 a tube but down to £11 now.

Best gasket sealant you can buy..

Err - wouldn't the grease and cardboard carbonise and fail at engine temperatures?

The intake side of an engine is far cooler than the exhaust gas temperature.

If your cylinder inlet port gets to the combustion point of cardboard the piston would have seized in the barrel long ago..

Another recommendation for Hylomar or if you want metal to metal contact; Stag Wellseal. - But be warned, the latter should be considered as semi permanent.
