Status: offline 		Hi, I am new to this forum so bear with me. I recently bought an old Pitts special biplane. It has a 66 inch wing span. I was piloted by Charles Hillard and ran in world class championships in the late 60's and on through the 70's. I am trying to identify the original manufacturer and modifier of the engine. I want to sell it but I don't know how to describe it. Perhaps you can help me with this. I think the head is a Sachs 3.2 because it has the lettering 44 Zn 18 on the casing. Other numbers on the casing are OB, ++, V, and W2. The rest of the engine and prop mount I have not seen while searching the internet. The crank case is machined aluminum two piece with a flat plat on one end to mount the base and six bolt prop mount on the prop side. It does not look like the same material as the head. There is also a base mount  shaped something like a wire spool to bolt the engine to the firewall. This is an older engine with a fiber block type ignition advance, a Bennett exhaust and a Welbro carburetor that is only marked with a DO next to the fuel inlet. The ignition block is a CD ignition made by CH Electronics Inc. in Riverton, WY. There is no prop. Could you please let me know if you can identify the original maker? It seems to have excellent compression and was recently run for a few minutes. Would it be hard to find parts for and is it worth restoring to flight or would I be better off looking for a newer engine? 

Thank You. Peter

A fiber timing block usually means an older A&M. Remoce carb and look at tbe rod. Alumiun rod is junk engine, copper/bronze rod means good engine.

Status: offline 		It's an aluminum rod. As for picture size I'll try some smaller ones if 600x 500 is too big. Hmmm...480x 400 no good either. I'll try just one. Hmmm...nope, no luck.

Apparently I will need better instructions on how to upload pictures to this server. What is the size limit?

Anyway, I'll follow the link from CK1 and see what I find. Any ideas what the junk ones go for on auction?

Thanks

They come out sized just right.

Status: offline 		The plane is a Byron Pitts . The black plastic mounts on the back of the engine came with the Byron Kit .
The plane can be a great flyer if it is not to heavy from fiberglass and repairs to the foam . Beware gass will eat the foam quickly . If the A&M 3.2 has the alluminum rod most knowing buyers will pass on it as a useable engine . Changing the crank over to a Sachs crank and rod will make it a great engine again but may be too costly to be worth it.

Status: offline 		OK, well I bought the whole plane for $100 so I am thinking I did alright anyway. We have a local club down at the Kona airport so I will take it down there and see what they think. I don't have a controller but maybe someone there will want to get it flying. It doesn't look too heavy yet.

Thanks for all your help.

Peter
