Did you also check/clean/replace the fine fuel filter? What was the fuel pressure reading when the problem occurred? When it occurred did you try pumping the primer pump just to see if it had any affect? Did you try isolating the misfiring to one mag or the other and if so, what was the result?

With the blurb in Sport Aviation on the subject I'm sure many of you 52 drivers have , like me first annual we found a screw stuck in the elevator pulley. Never really thought it was a chronic problem but maybe i was wrong. Dennis is working on a barrier for this (thank you , Dennis) but there may be another answer. Pulleys are for continuous motion, like a fan belt. Why couldn't the limited motion of the elevator be controlled with a push rod? C'mon you engineer types, we're Experimental. Would that mod be too complicated? bob ----- Original Message ----- From: Subject: Yak-List: Re: Yak-List Digest: 2 Msgs - 10/31/03 > --> Yak-List message posted by: N13472@aol.com > > Has something changed? why has the list quieted down > > ________________________________ Message 4 _____________________________________ Time: 05:39:12 PM PST US From: "Lee Taylor " Subject: RE: Yak-List: Re: Yak-List Digest: 2 Msgs - 10/31/03 --> Yak-List message posted by: "Lee Taylor " Re FOD. I am not familiar with the exact details of the tail cones involved, but what would be the problem with just a simple, cleanly-cut hole in the exact bottom of the tail cone skin about two inch square immediately in front of the jam problem area? That way anything small would automatically fall out, (screws, etc), and bigger things would potentially fall out partially. I doubt seriously there would be any actual structural considerations.

Dennis Savarese" Personally I would rather prevent it from getting to the elevator bellcrank than relying on a hole in the bottom of the tail cone to possibly allow the FOD to fall out. The hole wouldn't have worked very well for Alan Cockrell's vice grip incident.
