"Thank you for the update on this Mark.
I also have an A65 running a wood 72/42 prop and noted in some old literature that it called for a 72/44. I’m in the process of selecting a new prop and concerned about climb performance with a 44,…"

In addition to Brett’s info above, my local engine rebuild shop sent me a photo from a later Continental engine manual, X30010.

Is your bird flying John? Or are you in the process of restoration?"

"Tacho failure update.
The drive gears in the angle drive have worn out, hence the reason for the tacho to cease operation.
Obtaining any parts or even a tacho in Australia is proving difficult. I’ve found an angle drive on ebay, P-65535, but I…"
"I don't recall my Porterfield tach having a mounting like that! That's pretty Rube Goldberg, but just reminds us that a lot of cobbling can happen over eight decades. Fortunately, we have many of the factory drawings available so we can…"
Tachometer failure
Weather conditions were perfect today for committing aviation in the Skinny Bird. Until the tacho went out to lunch!Checking the cable down at the drive on the back of the engine, I found I couldn’t turn the cable with my fingers. After some fancy contortionist manoeuvres I managed to remove the tacho from the instrument panel. The tacho is held in place with 3 screw clamps, one screw being positioned at about 1 o’clock, I don’t know how I’ll get that one back in.The tacho is very firm to turn,…See More
"Great info Brett!
I went back to 2 different A65 manuals I have thinking I may have overlooked the spec, but you’re correct it’s not in there.
I appreciate your help!"
"Fantastic!
Great photos!
Thank you sharing!"
"Steve,I found this in the "Maintenance and Overhaul Manual With Spare Parts Catalog Models A50, A65, A75, A80 Continental Aircraft Engines" dated 2-15-48. These older manuals contain information that for whatever reason Continental…"

The new bushes are Superior Andy. Not sure if I should do anything about replacing the washers? I could turn them down to size in the lathe?
Brett your attachment is very useful, thank you.

That's a pretty creepy PM, Steve. Tom Porterfield approved him before I could check him out with our other ORA members. I'll just delete him and be done with him. Thank you for bringing this to my attention!

- The Collegiate is a great tailwheel trainer. She was the favorite among most CPTP cadets.

Steve,
I don't know much about your Porterfield. Donald Bishop owned it from Bowie, Texas, about 75 miles NW of Dallas. I'd talked to him some and he told me it was heading to Australia.
I hope you don't have to wait too long for the Slick magnetos. Good Luck.

Welcome to the Porterfield Airplane Club Steve.
It's cool to see that Porterfield again. I believe it is the same one that went to Australia a few years back from here in Texas. Good luck on your transition to tail wheel flying.

Welcome to our wee club for the skinny birds, Steve! You’ll find a lot of information on the Collegiate, scattered about the website. Once you get acclimated to the claustrophobic feeling of having the instrument panel a foot away from your face, she’s a real sweet plane.
Soft landings, Andy
