    The stock filter is really a what we called a "cheese grater" which was really a flame arrestor, I removed it to gain a little MAP at altitude. Bill Blackwell in Arizona sells a foam sock to fit over it.

    The correct CJ screen has the cheese grater expanded metal, then over this is a super fine brass screen. If you don't have the fine brass screen I believe Bracket make a sock type filter for the CJ. Or you could use both if you wish, down side is that it will cost you almost a inch of MP.

    Subject: Kimball Clean Kit
    Ok, if I wanted to order one of these springs, where would I find one? _____ From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com] On Behalf Of A. Dennis Savarese Sent: Saturday, August 26, 2006 8:18 AM Subject: Re: Yak-List: Kimball Clean Kit It's under the cap where the oil pressure adjustment screw is on the right side of the oil pump. The adjustment screw applies the pressure to the spring that pushes on the pressure relief valve. Remove the cap on the right side of the oil pump. Before you remove the adjuster screw etc., rotate the screw counterclockwise and count the number of turns until it comes out. That way you'll have a starting point to resetting the oil pressure. Loosen and remove the large nut and pull out the spring and valve. Check the spring carefully. If it is bent in anyway, replace it because the bent spring will not allow the valve to seat properly. The valve itself will have a groove in it from where it seats against the valve seat. The valve seat is not like a normal valve seat which mates perfectly to the valve. It is nothing more than a machined hole. That is why there is a groove around the valve. So don't try polishing the seat. Just make sure there is no buildup of any kind on the seat and it feels smooth to the touch. You can polish the valve to remove the groove and reinstall it. If the spring is in tact, flip it 180 degrees and reassemble everything except leave the cap off because you will have to adjust the oil pressure. Turn the screw in the number of turns you counted when you removed it. Then run the engine and reset the oil pressure to the desired level.

I know it's on the oil pump but do you have a picture or something??? Since about the last 100 hour check up we have this problem..it looks like it's worth looking in to. Hans _____ Van: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com] Namens A. Dennis Savarese Verzonden: zaterdag 26 augustus 2006 2:34 Aan: yak-list@matronics.com Onderwerp: Re: Yak-List: Kimball Clean Kit The oil pressure relief valve in the oil pump and the spring that applies the pressure on the valve are the primary problem with excessive oil drain. I have seen the spring bent and also broken. Both caused the valve not to seat. I have pulled the valve out, polished out the groove, reinstalled it and stopped the excessive oil drain. Fix the pressure relief valve and/or the spring and you will basically eliminate the problem. Dennis ----- Original Message ----- From: Bitterlich, <mailto:mark.bitterlich@navy.mil> Mark G CIV Det Cherry Point, MALS-14 64E Sent: Friday, August 25, 2006 3:19 PM Subject: RE: Yak-List: Kimball Clean Kit And the oil safety valve will work perfectly UNLESS: 1. You are out of air and decide to prop the engine, which sooner or later all of us will do. 2. Use the manual selector valve handle on the start solanoid. Please do not misunderstand me. I think Kevin's product is noteworthy and I will eventually buy one myself and install it. PLUS, the current installation methods include safety designs to prevent engine damage/loss, (such as the mentioned oil safety switch) but they are not fool-proof. The ONLY method I can think of that would be 100% effective would be to tie the MAG P-Leads into this switch, would would automatically ground them if the oil valve was closed, thus totally preventing engine start... and of course that adds the potential of other things going wrong. Just being the Devil's Advocate here... as I said, I think the valve is great.

All these items were originally developed for the Pitts model 12. As you can see, the page is listed as the moose support page because we offer these items to Murphy Moose builders as well. Yes, you can use the oil safety switch on an electric start engine to prevent starting without the oil valve fully open. moose support <http://www.jimkimballenterprises.com/h_support_moose.html> page Sincerely, Kevin Kimball, VP Engineering Jim Kimball Enterprises, Inc.
