The iFly has been sold!

Posting for a friend. His email is attached, here. ---------------------------------------------------------------- I just removed my iFly 720 GPS from the aircraft. It was mounted in panel and

Thanks Bob for the additional facts. Interesting. Will talk to Gary Hertzler about it for some insight of the cowling openings. I will focus mainly right now in trying to break in process and

Thanks for the input Gary. Before the OH, I didn’t have the cooling problem, just the regular EZ overheating if too much time idling on the ramp. Carburator WAS replaced with an OH one. I need to

At takeoff the engine is making the most power and has to reject the most heat. If it was running too rich it would run cooler. If it was running very lean it would not put out takeoff power and

Afif, Mark's right. Rebuilt engines ALWAYS run hotter till the rings break in. This sometimes creates a dilemma. You need to run the engine at at least 75% power to break in the rings properly which

YOU ARE CORRECT. I should have mention the hours. Just approaching this conservatively.....First OH and not afraid to ask!!! Thanks for the clarification and will continue to "EXPERIMENT" with

Thanks Mark,,, I will look into it methodically and report back on this issue. I do know I have my engine timed at 25deg BTDC, My engine only has 5 hours after OH. Regards, Afif

Great....Thanks for sharing....! Afif

If the your engine cooled adequately before overhaul, and the only changes you have made was an increase in compression ratio to make it 160 hp, the problem is not the cowling. Two additional things

Thanks for sharing the pictures..... Regards, Afif

Lew Miller and I both have done the mod on our 0-320 Longezs with Ellison TBIs. He had the same success with cooling. This what Mike Melvill came up with. I purchased the carbon fiber cowl from

Hi Gary, Can you explain free flowing exhaust? Greg Norman

Could you share some pictures of your cowling configuration??? Thanks! Afif

I have the same scenario......Alarms immediately after take off and while on Climbing!!! Very Interesting..... Afif

Jim, What you describe your engine is doing is exactly what I and others have witnessed. When I researched for info, I found that Lycoming specifies certain O-320 engine models for different
