It took me a few months just to figure out how it worked. The problem with it is twofold. First is that you have to have a -9 case. Do you have a -9 case and I mean crankcase AND accessory case? Second is that it does not have an oil seal where the shaft exits the oil side of the unit so the starter has a built in oil leak. Still interested?

I have the drilled con rods and the waffle pattern pistons. The engine is now mostly together and I am looking at 2 other things now: 1. I have the old Case magnetos and had pretty much made up my mind to bite the bullet and buy new Slicks, however out at the airport yesterday I was talking to a guy with a nice Aeronca Chief and he said that the Case mags had proved over the years to be very reliable, more so than the Slick's. His advise was to very carefully evaluate the Case mags. Any comments on the Case mags???? 2. If I decide to go with the Case mags does nayone know where I can get some non-shielded Champion C26 spark plugs(or equal)???? 3. The carb I have has no mixture control. I can't see where it could have been removed either. Did some of these engines have non adjustable carbs???? I will take the carb tomorrow to a old time aircraft mechanic and see what he can tell me. Thank you again to all for the great information, it sure makes this e-group worthwhile. I am hoping to fly this summer.

They are very reliable and according to my IA there has never been an AD on them. The only problem that I have had with them is that the internal grounding came loose on one during an annual. That led to an accidental start when we were getting ready to taxi back to the hangar. Not a real problem because the person propping knew what he was doing. I have one with an impulse and one without. There are manuals for the Case mags online at http://www.taylorcraft.org. Go to the technical resources page and you will find pdf files that I scanned.

Being a "B" model would lead me to think that it might be a "improved" version???? Can anyone shed some light on this??? Thanks Les ________________________________ Message 5 _____________________________________ Time: 02:17:44 PM PST US From: "Christian Bobka" Subject: Re: Pietenpol-List: continental engines --> Pietenpol-List message posted by: "Christian Bobka" Les, I have not done my homework on this YET but maybe the B is the non adjustable mixture carb.

As for C-26's you might look at fly-in flea markets, I bought 4 sets for my Menasco and 3 sets of BG plugs,although everyone says that the BG's are junk... They all were either new or remanufactured, the reman ones look just like the new ones, only way I could tell is the tube they came in had reman printed on it. I have a Marvel-Sheveler (misspelled I'm sure) MA-3 for a Lycoming O-145 that has no mixture control. I don't think I'd worry too much about it, I wired mine full rich on our Piper J-5A, I'm not much on leaning, seen too many guys ruin perfectly good engines with that little knob, although it would take some fear out of shut down. Also my two cent's worth...if the Case mags are working fine I wouldn't change them out... but if you do I'd be very interested in them for my J-5 Al Latham ----- Original Message ----- From: "Les Schubert" Subject: Pietenpol-List: continental engine > --> Pietenpol-List message posted by: Les Schubert > > Chris > Thank you for the information on A65 vs A 75.

I do have a -9 set-up. Is there any way that you can see to modify the unit to incorporate a oil seal, Having a J-5 with a slick black belly isn't something I'm very interested in... From what I've seen, I'm just starting to look into jacking up the HP on an A-65, with some parts / $$$ you can take the A-65 all the way to an A-80. You can e-mail me at goldnav@ipa.net, just put Al Latham in the subject line. With my new job I'm only at this address on some weekends.
