I have an O.S. MAX 40 FSR .. I have it disassembled for cleaning and new pinned ring. It appears that the Connecting Rod is Bent (very slight) foreward.. I wonder if it is designed that way as the engine has never had a reason to inflict such a reaction..

I probably should clarify - -I should have used the word - Very slight barely noticeable curve or bow. Does anyone out there have one apart and could check theirs to see if this might be in the design. I could straighten it but would rather not until I know it is not the norm.. I have been down that road before -- think something needs tweeked to find out a day later it was supposed to be that way.. Fun-fuN!! Piperjak

Here's a recent thread on the subject piperjak. http://www.rcuniverse.com/forum/m_36...tm.htm#3665039
Bottom line: not normal. I've done that myself a few times (re-engineer a project).
Mods, please delete. I didn't realize this was the O.S. support forum.

The connecting rod of your O.S. Max engine should have zero curvature. Yes, some have the main shaft slightly offset from the center of the rod-ends, but there should be no curve.

Bax, I agree,, I will probably just leave it alone - If I try to straighten it - I will end up just goofing something else up..
