Hello !
Recently we borrowed C152 from another club . After few flights one pilot reported that it takes effort of both hands and some weight to turn prop after the flight. When engine is cool the is no problem with turning the prop by hand.
Engine is 800 hrs after overhaul that was done in 2007, TT for engine is 6000 hrs. Overhaul shop owner says that there was a series of Lycoming O-235 with limited clearance on crankshaft and there is Service Letter or something to cover that topic. When asked "please give me the number of this letter" he could not remember but he says that engine is airworthy.
We made oil analysis and compression check - no problems.
Anyone of you heard something about such series of O-235 ?
thanks
