Kevin;If you've followed the DynaVibe thread on the Corvair list, you'll know that MarkLangford's silky-smooth Corvair is now running at ZERO inches per second readingon the instrument. If you think that I am too smart for my own good, goknock on Mark's door instead... HE is the consummate engine tuner and blueprinter!Mark flies behind a sewing machine, it's that smooth ;o).Today's engine run was a bit of a disappointment. What we have confirmed is thatthe engine is running lean with the slightly larger bore venturi that I installed,so tomorrow we'll pull the carb open again and reinstall the standard1-1/4" venturi that the specs call for. It's always fun trying to disassembleas little as possible of a Stromberg since all the fasteners are safetied andvery few of them are easy to get to with the carb and air box installed on theairplane. I wish I had the slim, nimble fingers of a 10-year-old girl whenI'm trying to get the nuts, washers, and safety wire all in the right places onthis thing... although putting the brass nuts on the exhaust studs runs a closesecond to the Stromberg for "tight quarters" work on these engines.In off-topic news, inbetween working on the Piet engine and replacing clevis pinson the tail feather hinges with slightly shorter (and more correct) ones, wehave begun reinforcing the bottom and chines of a Bolger Tortoise with glasscloth and polyester resin. Talk about a nifty little dinghy... my son and grandsonswill soon be playing with this little boat in the pond out at the ranch,catching largemouth bass from it and retrieving downed ducks from the water.This time of year, Texas is graced with hundreds of thousands of migratingducks and geese and it's a lot of fun to jump-shoot ducks from the small stockponds that are on the ranches in the area. The Tortoise is a nice little craftand perfect for the job. Oh, and then there's the conversion of a gas weedtrimmer to a little outboard motor for the Tortoise ;o) Never a dull momentaround here!--------Oscar ZunigaSan Antonio, TXAir Camper NX41CCRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Flying Xmas Gifts from the Goddess & Others
