Substitute poulan 2577 Rings?

Can someone please provide existing Poulan 530002577 ring measurements
for the 306 or 361 series?

Anybody tried using the Homelite Super XL rings in the Poulan 306/361?

The bores are nominal 1.812" in the XL & 1.788" Poulan, & both are flat ended so
should be able to file off the extra ~0.075" length to get a proper 0.008" min gap.
Only question is about the ring's "wall" differences, will the grooves be cut
to a different depth in the two manufacturer's pistons.?

Can't use metric type rings because of the different thickness, guessing 1/16" for the
domestic Homeys & Poulans, and then 1.2, 1.5, or 2.5mm for the range of imports.

Update

Feel kinda goofy answering my own question, but i just wanted to let the Poulan 306 owners
know that the Homelite Super XL piston rings from Leonidas the Greek worked fine for
the obsoleted P306 #530002577 substitutes. They are 1.7890" diameter when measured
compressed closed over a 1/16" drill bit. The bit simulates the little groove pin ring keeper in the
piston ring grooves. They are 0.0625" thick & measure 0.070" in wall depth. Only around 0.020"
was all I had to remove to get the 0.008" gap clearance in the 306 bore, again using the drill
bit as a "spacer" with the feeler guage. The old rings measured 1.769" diameter over the bit.

Wasn't overly impressed with the new compression gain (134# new/120# old), but figure they
will seat in better after a few tanks of gas. Runs like a wildcat, and the exhaust tone will split
your ear drums open when it's buried in the wood. Muffs required. No squish check done, jug
was not decked & a stock new jug gasket was used for reassembly.

Thanks for that heads up!

Sounds easy enough even I could do it.
