If you have a POSA, > replace it before it cost you your airplane and maybe your life. > > Jim Eskildsen: 818-586-0349 Hello All, When I first started I had a POSA given to me and then I bought one with a float bowl from Rex Taylor. I had nothing but troubles trying to get both of them to run right. Eventually I put on a Tillitson float bowl and even today it still has the same carb on my 1835cc. The Tillotson is common on the Evenrude outboard engines, you may have to install the mixture control, some of them have it on. I think it was a 35mm, can't remember exactly at this time. Both POSA's went into the garbage and I am not sorry for that. Many guys cried, and wondered why I did not give it to them. I think I saved others a lot of trouble and they are all alive today. Am not recommending anything here, just history and you can take from it what you want. Although I have seen the sliding body types(POSA) similar on engines from 1918. Boy, can't believe this teflon tape on aircraft hydraulics and fuel lines, in all my years in aviation have never seen this of even heard of it before. You'll plug up something, just not good aeronautical practice. If you flare properly it will never leak. Flared quite a few on my KR and cracked a few, but never had a leak. Good Luck, get a good float bowl!!!

" I'm ashamed to say I just spent two years dicking around with one of those, on my outboard motor. But, it was safe to put it in the water and test and try. The float level was not right, as set by a mechanic / wizard (OH! Well!) Otherwise a real success. My motor is a 1968 and still going strong (again). Buy a really good carburetor, an Ellison if you want to fly inverted, or one of Steve's. Read the info on the Ellison web site and especially the excellent info on a FILTER which immediately precedes the carburetor and follow that as a minimum.

Posa carbs work perfectly. It's just that some people don't understand basic mechanics and fuel metering systems. It's not the carb., it's the mechanic who sets it up. Posa carbs can't be taken out of the box, and put right on the engine, and expected to run. The metering needle has to be modified, and then locked into position. They also need a mixture control, which HAPI used to provide. I've had the usual problems runing my engine with the Posa at first, but I solved the problems before I went flying. It's always worked well for me. mailto:joejbeyer@earthlink.net Portland, Ore. ----- Original Message ----- From: To: ; ; ; ; Sent: Wednesday, April 12, 2000 6:48 PM Subject: Re: KR> Fuel pump dilemma > In a message dated 4/12/00 11:54:12 AM Eastern Daylight Time, > jim.eskildsen@West.Boeing.com writes: > > << I agree with Ronald.

Each of us hopes it will never happen to us. The posa carb has had problems with the neddles backing out since I first built N110LR in 1984. Hapi engines put out a statement and set of instructions. The letter was dated April 1, 1984. It is too much material to include here. If any one is still flying with a posa, you need to check to see if the instructions for modification was completed on your carb.

Do not allow the Teflon tape to go past the end of the threads, when putting it on the fitting. This way no Teflon will get into the interior of the fitting. When removing a fitting, be sure to clean the female fitting of lose Teflon that may be left in the fitting threads. Never use Teflon on a flare fitting.

I've used Teflon tape on motorcycle fuel lines for years, without the slightest problem. As you said, only on the male fitting, so when you screw it tight, the excess will be pushed out rather than in.
