My Feedback: (3)

Hi everyone. I wanted to thank Lightning Fan as well as others who have posted on this thread. I recently was able to acquire an OS FR5-300 radial from a lady whose modeler husband had passed. I have torn down/rebuilt/refurbished many 2 and 4 stroke engines but never a radial so I was quite happy to find this thread. I found the photos and information very valuable. So after reading thru this thread I have reassembled the engine. I used this thread to disassemble and reassemble the engine. To clean the engine I soaked all of the various parts in automobile parts cleaner for a day or more. Once clean I began the reassembly.

However, I am trying to find info on valve adjustment (not the clearances but the sequence in which the cylinders fire (i.e. firing order)) so I can properly adjust the valves. I looked on YouTube and could not find anything . Can any of you help? Also, what size 2 or 3 blade props are any of you running on this engine?

Thanks for your help,
Ed
