Re: Cowling Mods for 160HP Engin

Jim Evans

Gary:  I saw your post on the carb change.  I have had similar problems with mine for years and suspected carb issues.  Can you explain what overheating symptoms you witnessed as a result of the wrong carburation?  Mine overheats on CHT almost immediately from takeoff through climb.  After leveling off in cruise and given time to cool down, the engine runs pretty much normal.  Any input would be appreciated.

Hope you have a great day.

Make sure you have the correct carburetor. For our application with free flowing exhaust you need to use the following carb. 

Model # 10-3678-32
Lycoming part # 72394

This carb unusual set up to provide extra fuel flow.  

I have seen switching to this carb solve many cooling issues.

I recently factory overhauled my O320E2G Long EZ and upgraded from 150-160HP. I've done a couple fo flight and I've noticed higher engine temperatures (in the 420+ degF) than my previous configuration. I have a conventional updraft configuration in my LEZ and I'm wondering if its time to modify the cowls for additional cooling. I'm also planning of replacing the straight pipes too.... Attached are pictures of my LEZ with current cowlings....Would love to hear of experiences of LEZ with 160HP engine and temperatures range operation....Thanks in advance!
