19richie66 17,633 #3 Posted June 27, 2021 Have to admit.... when I first saw this I thought it said “onion rings”. No help at all I know. Good luck in your search. 1 Share this post Link to post Share on other sites
onanparts.com 185 #4 Posted June 28, 2021 There were two different ring sizes found on the P series Onan's. You must measure not only the bore, 3 1/4 is STD, but also the compression ring thickness to determine the correct rings. 1/16 part # 113-0310, or 5/64 part # 113-0314. No caliper or mic handy? Pocket change will do the trick...:) Share this post Link to post Share on other sites
