Base gasket delete worth it?

[tomalophicon]

Hi all,
I have a Shindaiwa 577P that I love using. Has good power for purpose etc.
Just for chits and giggles I measured the squish through the spark plug hole with .060" solder and it barely even touched, let alone crush the solder.

The base gasket is .020". Will it be worth taking the gasket out still to have .040"+ squish? Is there likely to be a compression increase or does it need to be around the 020" in squish to achieve that?

Cheers,

Tom.

Yes, deleting the gasket will increase compression and it is noticeable but not ideal, even though it will increase power, I wouldn`t hesitate at doing it.

.060" is a lot but not unheard of... Be sure you measure it both sides & all the way to the edge of the cylinder.
That being the case, a gasket delete will definitely improve things

Delete it, but @J D has a good point. I use thin solder (maybe .030?) and use 4 small pieces at the edge of the piston, 90* apart. I use a dab of grease to hold the solder in place.

If you really do have .060" clearance, I'd delete and measure again.

I use Loctite sealant but there are a few other options, too.

Hi,

I measured in multiple different places all around the cylinder. There was barely any contact anywhere.

I ended up pulling the cylinder and the gasket in there crumbled into several pieces. Cleaned it up and added permatex anaerobic gasket maker 518. Keen to see how it turns out. It now measures around .039.

Cheers for all the replies.
