Perhaps Francis could be persuaded to accept one or the other methods of monitoring power.

He did, AFAIK after test flying he elected to put his Warp Drive back until he pulls the airplane home for annual. He was not prepared to wait weeks for his full permit and miss any late December flying. Isn't Bryan in Florida right now? Graham -- No virus found in this outgoing message.

Worth a try I would say. The "squared" rule was applicable to radials, then carried over (rightly or wrongly) to 'flat' engines.

If anyone else would like details please let me know and I will send. Note, I need your email address (not the matronics list address!) Here is where you can purchase the Lo Gauges (to make up the balacer setup) in the UK at a very reasonable price, along with a load of other goodies you may need (eg: compression tester - remember you may need an adaptor to fit the 912 cylinder heads). http://www.mgocaccessories.co.uk/acatalog/Gunsons.html Note: Dont be tempted to purchase the Gunsons carb balancer from here - it is not suitable for setting up the Rotax carbs. ________________________________ Message 7 _____________________________________ Time: 02:54:23 PM PST US Subject: Europa-List: RE: Carb Balancer From: "SteveD" 2.60 REPLY_TO_EMPTY Reply-To: is empty --> Europa-List message posted by: "SteveD" Carl, If you sign up and post your photos on the EuropaOwners on Europa-List. The photos will post as a link automatically and will be sent to the Matronic list server. You do have to join the EuropaOwners with the same email address that you use with matronics. When I get some time and look into the specifics of the carb balancer I was think of making an electronic one out of a basic stamp and some pressure sensors. Doesn't look to hard....

Consulting the manual I notice that no specific mounting method is shown, although it does say what hardware to use for temporarily mounting the servo tabs after the first hole is drilled whilst the rest are drilled. What is everybody doing in regard to mounting these? Is it blind nuts or lock nuts? Regards, John Lawton Dunlap, TN A-245 (Firewall aft airframe complete. Just post curing parts...)
