That looks like it matches my GX-200 best, Phil.
Top part on my Buddy's Tillotson is different.
I would just get the GX gasket & the ''China clone'' one also,, from NR racing.
One of them is only like $1.29, & the other is under 2 bucks.
Shipping would be the same for both together also.
FYI,,
I would ''not'' use silicone on the cover gaskets,, & I don't use sealer @ all.
Those gaskets are thick enough to compress & give a good seal.
What you see squished out on the outside, is going to be the same on the inside,, & will eventually come off,,, & potentially plug things up in there ect.
Plus not using sealer,, you probably will not harm the gasket if & when taking the cover off again, if you do it gently & evenly .
I have never torn a gasket on one of these sizes.
If you get a spot with the gasket sticking on the case,, just use a razor blade behind ect. to gently work it loose.
Also not using sealer, will help in optimizing the side thrust tolerances of the crank.
The sealer on both sides of the gasket,, can also potentially give you around an extra 0.004+ thousandths of side play or so...
Lastly,,
I would ''not'' use grease on the crank seal lip ect. either. It will attract ''a lot'' of dirt ect.
Just cote the seal lip ect. with a smidge of oil that you run in the engine.
& also smear a bit around the step on the crank.
The seal will also do it's job better with ''just'' a bit of assy. oil on it.
