Some plastic will swell with some gasolines . . .

One of my 7900's was originally a 6400 with the catalytic muffler.

I changed the cylinder/piston, decal, muffler/spacer, and installed a HD air filter.

We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .
