I have always intended to have a fire extinguisher, but have not bought it yet, doing that today. For all of my firewall forward fibre glassing I added a fire retardant to the mix. Probably only used about half a cup for the whole job. It is a white powder that is added to the resin mix, I don't know if it works but I'll build a test piece and burn it when I next modify my cowling (in the next month or two).

After diver dumping (hauling skydivers) all day yesterday in a tired C182 I was looking forward to some KR time today. I was off to the airport at 7:30AM with blue skies and light winds. I rolled the trailer out of the way, rolled out the Rans S-6 a friend of mine has in the hangar, and rolled out the KR. With everything put back in place and a quick preflight, I was ready for another YEE HAA kind of day. A quick shot of prime and a pull on the starter handle had the blades rotating. Wouldn't fire a lick. D#m*, must have flooded it so I kept the starter engaged and went to full throttle to try to clear the induction system. Still didn't hit a single time. O.K., let it set for a minute or two and let the gas evaporate. Tried it again and it coughed to life, ran maybe 10 seconds, stumbled and died. HEY, IS THAT SMOKE ROLLING OUT OF THE COWL !! SH*#, NOW WHAT DO I DO, KEEP CRANKING OR RUN FOR MY LIFE. I shut off the fuel and jumped out. As I reached the front of the KR I spotted a two inch rolling flame on the bottom of the cowl with melting, burning, dripping paint and what I learned later was melting, burning epoxy!!!!! DUMB MISTAKE #1 : I had flooded the engine. Jeff Scott told me, and maybe the net, on at least one occasion that the 0-200 is an easy starter without prime. I never listened and have on several occasions flooded the engine without any problems. DUMB MISTAKE #2 : No fire extinguisher handy. I quickly remembered the two gallon weed sprayer setting in the hangar that I use to wash down the engine. Hoping it had some water in it I made two or three 20 foot leaps to the hangar and back. It was nearly full !!!! I know you're not supposed to spray water on a fuel fire but hey, MY BABY WAS BURNING !!!! The first shot of water quickly extinguished the burning cowl on the outside so I stuck the nozzle in the access hole for the oil quickdrain, pumped like hell on the sprayer and directed the nozzle in every direction I could inside the cowl. It probably only took 10 seconds to extinguish the flame but I think I pumped the sprayer half empty. Thinking I had the fire out I ran to the truck to get my battery powered drill and bit to remove the cowl. Not knowing what shape the battery was in I grabbed the extra battery also. Turns out they were both nearly run down but between the two of them I removed the cowl. Soot everywhere but no damage at all that I could detect to the engine. The paint was not even scorched on the carb heat box. The cowl was another issue. An area about twice the size of your hand and fingers was TRASHED ! The epoxy had burned completely out of the glass cloth and you could see daylight right through the weave in several areas. I have no clue as to what ignited the fire. I'm sure I flooded the engine and supplied the fuel but there was no hint of a backfire or anything that would hint of trouble. Lesson 1: Raw fuel outside the induction system is BAD NEWS! I may remove my primer and will use a different starting procedure from now on. The engine will be cranking before I induce any fuel into the system by either cracking or pumping the throttle. Lesson 2: I intend to purchase a small fire extinguisher and carry it in the KR. Lesson 3: Resin and paint can continue to burn even after the fuel (gas) has burned off. When I repair the cowl next week I intend to build in a small stainless or aluminum catch basin under the carb that will route any fuel leakage to the access hole for the oil quickdrain rather then let it possibly pool in the cowl. Being a taildragger it will have a nice natural incline. If a fire does develop, it will keep the flames out of contact with the resin and what little fuel stays on the metal will hopefully burn off quickly. 1000+ hours and this was my first experiance with an engine fire. Hopefully it will be my last ! I'm sure others may see other lessons to be learned here and if so, good. As for me, I'M ONE LUCKY DUDE !!! My "Little Phoenix" will rise from the ashes to fly again !!! YEEEEEEEEE HAAAAAAAAAAAAaaaaaaaaaaaaaa !!!

When during a fast low aproach at full throttle the engine skipped a beat. Just one beat but it was heard on the ground and I d mn sure felt it. It has done this before and I was thinking that the filter after the Gascolator was just to much for the gravity feed carb. IE running lean, I removed the element and it seemed better. I have the RevMaster 2100, 350 TSN, 15 TSTOH (pistons, head, cylinders, rings, auto spark conversion ) I have the Revflow "carb". I don't know what jet is on it. That is one of my weak areas of knowledge. OK gang any ideas! PS I was thinking aboput just replacing the Revflow with a new one but need to know what size that I need.

They are paid by tax dollars and can not refuse to do it and they must do it timely that is why the 6 week limit was imposed. He can't make you use a DAR.

It does tend to get your attention. In my case I believe it is related to over-leaning. If I lean to right to peak EGT at high cruise I can expect a "hiccup" within a few minutes. If I lean to peak then go 75 degrees or so rich "It" does not happen. I will not speculate on the mechanics of this phenomenon here. My carb is also a POSA type (Aero Carb) on a Revmaster 2100D. I do not use a filter other than the gascolator. Cheers Owen www3.sympatico.ca/omacphe "I was out flying for the first time in 2 months (due to job and WX).

I looked a long time for a good quality fuel filter that will take regular AN fittings and does not cost a fortune. I did some searching on Earl's after I saw your pictures and it looks like they have a very nice line of economical plumbing parts. Are they standard 37 degree AN fittings and where have you found the best prices on their parts? Here is one source I found that has pricing. http://www.amstreetrod.com/FuelSystemComponents.php4 And the home page here http://www.holley.com/earlsplumbing/index.html Looks like they have some really nice stuff. The fuel shutoff valves are a lot better looking than most aircraft types I have seen. The flared fittings machined right on their parts means you don't need a bunch of NPT to AN adaptors like a lot of other brands of fuel system components. Looks like they might have some nice oil coolers for our use also.

I'll have to give credit to OZ for getting me to think more on this, but suffice it to say that my fuel system is about to get a lot smarter. Go about 2/3 of the way down http://home.hiwaay.net/~langford/fuel/index.html#update for the update, if you must. I'm sure a lot of you guys are getting tired of this, but I think it's kind of fun, solving problems BEFORE they show up on maiden flight takeoff...

I have absolutely no leaks from any of their fittings, and I'm using their "cheap" (but lightweight) Pro-Lite 350 non-stainless hose. I get my Earls stuff from DCI Atlanta (404-522-3497), although my local speedshop guy swears he can get it just as fast, but then the FedEX man doesn't get to feed the dog that way! The Earls catalog is full of good stuff, such as my thermostatically controlled oil cooler bypass. There are way more fitting options than Wicks or AS&S have...
