Is they a service or repair manual for a 0320H2AD or a supplement.

There is a separate parts manual for the H2AD, but not a service manual that I'm aware of.

O320 H2AD

I have the 76 series engine overhaul manual and O320H parts manual on PDF's. Send me an IM with your email address and I'll send them to you if that helps.

I have the 76 series Lycoming manual, and built my H2AD as well as overhauled the carburetor and Bendix magneto. I am running mine in an RV-4 and having great performance from the "*******" engine many people shy away from. PM me if you have any questions that I may be able to answer.

I'd love to get a copy of that manual if you still have it.

Thanks,

H2AD info

I once had a long conversation with a well known engine rebuilder and owner of a large shop.

His pet project was the O-320 H2AD normally 160HP engine which he was convinced could easily produce 180hp or more with some mods. In fact, he had one in his backyard and tinkered with it.

I had one in my RV-6A and had excellent service and performance for minimal expense.
