puddlejumper 67 #1 Posted October 8, 2010 Was wonder ing about some Info I found on this site a few months back that showed a document comparing H35 h45 and h55. the document showed that all of these engines had same bore,stroke,anddisplacement. was wondering if they all had a oil pump.Basically Im wondering if they were all the same engine just with different carburation.See this alot in newer briggs engines. and was wondering if this was a way around my Engine delima. Well I should have dug alitte deeper in my papers (Inew I made hard copys of that info) anyhow the h35 wasnt listed but the h45 and h55 are identical engines and use all the same part numbers except for carbs. Sorry If I put anybody out trying to help when I already had all the info myself. Share this post Link to post Share on other sites
