I really love these small Continentalsand they continue to serve experimenters (and certified aircraftmanufacturers as well, in the O200), long after their designerscould have dreamed that they would.As I wrote in my article about them in Contact! magazine, theyare reliable, simple, and straightforward engines but theydo have their quirks and weaknesses. I'm no expert on enginesin general, but I would have to agree with what one writersaid about the earliest of the genre, the A45, when he statedthat it may be one of the simplest 4-stroke engines ever devised.Oscar ZunigaAir Camper NX41CC "Scout"Flying Squirrel N2069Z "Rocket"Medford, OR website at http://www.flysquirrel.net ________________________________________________________________________________Subject: Pietenpol-List: New Carb

So i found a new carb for my A.. i had a tillotson and was having a little troublestating it and getting it down to a good idle.I found some info on new model Zenith carbs and starting looking for one of twoor three models.I picked up a new in the box Zenith 14995.. it has a better idle circuit fromwhat i understand and better float.. there are 3 fuel ports..one on the back andone on each side..and the linkage can be attached on either side.. comes withnice linkage arms too..only took three blade and it fired right up.. way rich at first but a simple adjustmentand it was purring at 600rpm .. i was seeing about 1900 at full throttle..i think the carb was a good purchase.http://youtu.be/jWCVSiBuPxgdid a little fabric work too..jeffRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Re: Pietenpol-List: New Carb

Way cool Jeff. Sounds really nice and smooth (better than mine). That Zenith carb, it is new?, or a newer version of an old carb?That 1900 RPM static I think is very good. Mine is 1860.Also, looks as though we may yet have another Black and Yellow German coming down the line?.....

Here is my motivation for finishing the piet. I designed and built these about10 years ago specifically for the Piet. They will be finished with herringbonemahogany planking.--------PAPA MIKERead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/img_ ... ___Subject: Pietenpol-List: Re: New Carb

I drive a 1930 AA and it won't idle as slow as the piet..I'd bet there are are leaks around the throttle shaft in the carb i was using...that seems to be a common idle prob.I really thought about rebuilding the tillotson or a marvel i have around, thendecided why mess with an 80 year old carb when i can get a brand new carb withbetter tolerances and now wear.I'd bet your intake is fine..jeffRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Floor Bracing on extended fuselage
