Hello all you G.P's,Did you ever think about how much faith is put into the lowly cotter pin? I warn you, if you dwell on this subject too long you will begin to scare yourself. I remember a few years ago when I did a test run of my engine and I had the airplane completely assembled (no cover) with all the castle nuts just hand tight. After a few minutes of ground run almost every one of those little suckers was on the ground, control cables hanging etc. What if just one of the cotter pins failed on the bellcrank connections? I guess one can console oneself a little, by thinking that most of those pesky little critters can be inspected prior to each flight, but what about the ones you can't look at??? I have scared myself sufficiently, as to contemplate fabricating a "hybrid" safety mechanism for those hidden bellcrank connections............. How about this idea? Take a nylon lock nut, drill a cotter pin hole in it, so it can be threaded-on just short of being tight, and inserting a cotter pin. That way, you can have a nice warm, fuzzy, and secure feeling of having all those AN3 sized bolts double safetied.

Pietenpol-List: Re: Rounded Seat for Delrin Needle, Stromberg Carb, Conti...

Today I disassembled my Stromberg NA-S3/B carb to verify the venturi andjet were correct for my C-85. The venturi was correct and the jet appears toa #49 jet reamed to a #45 which is correct. I too have a neoprene needlethat appears to be in great conditiond, but the seat is a sharp edged one for the stainless needle. Dave, If Matt doesn't want you seat, I sure could use it in my carb. If hedoes, does anyone else have one they'd like to swap?Curt MerdanFlower Mound, TXRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/stro ... ___Subject: Pietenpol-List: Re: Rounded Seat for Delrin Needle, Stromberg Carb, Conti...

Matt, I found an official reference about the needles and seats.46-04-02 CULVER: (Was Service Note 6 of AD-730-2.) Applies Only to Model LCA HavingStromberg Model NA-S3A1 Carburetors Installed. When inspecting or replacing carburetor float needle or needle seat, a check shouldbe made to assure that when a rubber tipped needle is used, a seat havingrounded edges is installed. Sharp-edged seats, when used with a rubber tippedneedle, will cause sticking and cutting of the rubber tip. (This matter is also covered by Continental Service Bulletin No. M45-6 dated May25, 1945, and Stromberg Aircraft Carburetor Service Bulletin No. 71.)

Occam's RazorCorollary; If it's worked for hundreds of years don'tscrew with it.Also, if you want to continue this mind experimentto it's ridiculous conclusion, what have you done bydrilling holes in bolts thereby compromising theirstructural integrity? :-)Oohh... now I've done it! Is your wife going to wakeup tomorrow and find your pajamas filled with amindless puddle........?
