    Subject: Jihostroj prop governors
    --> Engines-List message posted by: "Gary Casey" <glcasey@adelphia.net> I'm curious if anyone has any experience with these prop governors. I've got one installed on my IO-540, but haven't yet run it. It has the advantage of being a few pounds lighter than the standard one and is 2 inches shorter, improving my inlet ducting a lot.

    Subject: high egt #2 cylinder
    --> Engines-List message posted by: "dave" <dford@michweb.net> I have an IO360A!A with egt/cht probes on each cylinder. No. 2 cylinder is my hottest for both egt/cht with egt at times 300 deg hotter than #1 at times , #2 1500-1550deg while cht may be 350-400. We have changed injectors with no change, changed plugs & range no change, checked baffling, closed off oil cooler behind #4 cyl (to check baffling also)no change. Some have suggested a possible exhaust valve leak. Would this show up on a compression check with a cold engine or does it need to be warmed? Dave Ford RV6

    --> Engines-List message posted by: James Baldwin <jamesbaldwin@dc.rr.com> Dave - Have you carefully checked the location of the EGT probe and its relative orientation to the others? You didn't mention the CHTs of all cylinders. What are they? It doesn't SOUND (emphasised because we need more data) like a mechanical issue as much as an sensing/indication issue. Did you swap EGT probes? The location of the probe in relation to the flame front from the exhaust port is really important on a RELATIVE basis. Whose system are you using? How did the plugs look relative to the other cylnders? A standard compression check, performed on a warm engine, will also tell us a lot.

    Subject: Re: Propeller question (OFF TOPIC)
    --> Engines-List message posted by: LessDragProd@aol.com Hi John, The CS aluminum 2 blade MT propeller is hydraulic controlled only. The CS 3 blade MT propeller is available with an electric or hydraulic controller. This blade has a stainless steel leading edge. It is a certified propeller design which meets the rain and ice impact requires of the FAA. The MT propeller blades meet the same requirements as an aluminum propeller. The stainless steel leading edge is just three times more resistant to damage than an aluminum blade. There are two recommendations for the MT propeller on a floatplane. Order the propeller with the extra corrosion protection for the internal parts. $300 extra. Order the blades painted Dull Gray with Gloss White tips. Free optional colors. Regards, Jim Ayers In a message dated 05/23/2005 11:14:36 PM Pacific Daylight Time, jgswartout@earthlink.net writes: --> Engines-List message posted by: "John Swartout" <jgswartout@earthlink.net> Is that CS prop electrically or hydraulically controlled? My engine is not built for oil-powered prop governors. I am, however, confined to metal, because this is a float plane.

It came from another bulletin board. I thought it might be useful for your review. J!LL http://carneyaviation.com/enginefire/ This list provided courtesy of Safe Data, Inc.
