Gasket delete gasket maker

[Craigb]

Anyone used this for base a gasket? High temp resistance.

I usually use Carplan red which goes up to 260 degC, at 399 this is fine. The base of the cylinder doesn't get that hot, the exhaust port does!

[Ledburyjosh]

So is a Gasket delete a case if removing the Gasket to to lower the casing to improve compression?

Does it need to be done along side other 'port' work or can it be a stand alone thing?

[Craigb]

Just so you know I’m no expert but I have had some good schooling on this forum. I am indeed removing the gasket to increase compression. You don’t need to do anything else to the saw other than make sure the gases can escape, aftermarket muffler or you can open up your own muffler. This entry level work is like putting a putting a cone filter and a performance exhaust on a xr3. Anyone can do it but the difference is it works. No fancy porting required.

Dirko HT is great. Think that's what Stihl endorses. The tube comes with a little twister thing so you can get every last drop out as well.

Gasket deletion or fitting a thinner gasket will bump up the compression and make her rip more or explode faster. Measure your squish before and after to make sure it's sensible.

I fitted an aftermarket cylinder gasket once without thinking about or measuring squish and later realised the squish band was 0.017" which is apparently dangerously low. Conventional wisdom says aim for 0.020" minimum.



Way easier to understand with a diagram for me. Lowering cylinder changes squish and the goings on of the combustion chamber.

Dirko is good stuff...but a pig to get off your fingers afterwards.....and everything elso on the engine you touch!

Just to say that Dirko red acetic silicone dissolves in petrol like most other silicone sealers and therefore is not suitable for 2 stroke engine crankcase joints or any carb applications etc.. you will end up with an air leak.. sooner or later.👎

 

This however has been my go to gasket sealant for decades, originally developed by Rolls Royce.

I have always used Hylomar from back in the 70s . I initially used it coz I liked the " electric blue " color 🙂

Started using Hylomar working on Triumph car engines with my dad, as you say in the 70s. It was easier to use and easier to clean after than stag paste that we used before, which set hard on the gasket faces.

If you need a sealant thats oil and fuel resistant, then this is what we have used for the last ten years or so.
