Poulan 3800 has two thick rings and an aluminum bore.   Randysenginerepair on eBay has a set of rings for 17.99 and free shipping.

The 3800 should be around 125 psi on the compression.

Roger I just want to make sure that I got this right.

Poulan 3700 3800 same bore?

3700 chrome bore.

3700 thin rings or thick?

3800 bare bore.

3800 chromed piston.

3800 think rings.
