0-145 and 100LL

[joelharris]

gents,

At the risk of sounding like a complete ignoramous what concerns should I have running 100LL in my 0-145. I can only get 80 at one location out here and it is kinda a pain in the backside.

Joel,
I have a BL 65 close to completion. I bought the Peterson STC for auto fuel. If you don't want to go the auto fuel route try using TCP, a product that you add to the fuel to help scavange the lead.
Also, some folks have used a mixture of 100LL with auto fuel with a four to one ratio. That is one gallon of 100LL to four of auto fuel.
If I am correct, the minimum octane for these engines is 73.

I was thinking about the auto fuel route but out here in the far west we are burning this oxygenated fuel that has some weird stuff in it...thought it was better to stay away till I can learn more about it.

I'll give the TCP a try, seen it around but never paid much attention.

I bought some parts from El Reno for my engine in the LP-65 a few years ago, any tips on a better source?

Joel,
The only other source of parts other than fly markets that I know of is Jes Hackenberg of Hackenberg Aviation in Montoursville, PA. If he is still around, he was overhauling 0-145 engines. I was told that he bought up the remaining stock of 0-145 parts when Lycoming discontinued dealing with those engines. He will swap NOS parts with you also. Is there anything in particular that you need? I might be able to help you. Also, check the web sites for any plane that used the 0-145. Mooney Mites have a site that I see parts in once in a while. Also the Vagabond used that engine.
That exhaust system with the muffler may fit under a Tcraft pressure cowl although the legal ramifications may prohibit that without some type of approval.

0145 and 100 LL

My A 65 wish has very good compresion (1700 hr- 74 74 74 72)
does no like pure autogas 87 octane. It will KNOCK!
Lack of Octane. Not good for the engine.
I mix 1/3 100 LL and 87 octane and she is fine.
Put 100 LL in the wing tank and then refuel the main with auto gas but leave some room for 100LL and let some drain into the main and top of the wing with autogas. Make " stol" to lift the tail
if the fuel dont drain. Work = money saved.

Fuel mix

Len,
Down here in the desert, I run 1/4 100LL, and 3/4 Autogas. The engine does not make any ugly noise, makes plenty of power, and I don't lead-foul the plugs. WhenI first got the plane, it was filled with 100 LL. After about ten hours of operation, I pulled the plugs, and the lower ones were just beginning to show signs of lead fouling. I switched to the current mix, and everything is fine. You started off with what I think is the FINEST two place lightplane ever designed, I waited untill I had been flying for 40 years to get one. Why don't you post a photo of your "baby" for all of us to enjoy. Sabrina
