Cylinder base sealant, expensive Stihl silicone or hi temp red RTV ??

When there are products that don't do that I don't see the need nor the desire to use any silicone based sealant in a two stroke engine.

Honestly, I have to agree. I like how easy it is to apply and it hasn’t let me down, but since seeing this thread and the other forum covering it all again, it makes me want to try motoseal once again. It just sets so quick that’s all.

Here in Aus where temps are warm all year round, you have literally 60 seconds to get parts together after it’s applied or it will have already skinned over then 24 hours to fully cure. Dirko takes about 10 minutes to skin over and then is ready to right away. No need to wait 24 hours. I guess that’s also why I have stuck wit it.

I'll say it again, best thing I've found is Permatex Motoseal, works, cheap, easy to find.

I've never used or heard of that particular product but just pulled up the data sheet. It appears it will work just fine and it's not silicone based.

Yes that’s correct, motoseal is chemical cure, it’s essentially the same as 1184, 1194, 1104.

Threebond 1184 or Dirko HT

Try this stuff, it’s all I use now, from Diesel engines , tappet covers that should have cork to chainsaws, and not excessively hard to pry cases apart if used on
