Brian, Don't know if this will be helpful or not, but is something to check. Under certain circumstances, my KR (gravity feed fuel system) used to either stumble or shut down during high speed passes and would re-fire as soon as the speed bled off. It turned out that the vent for the header tank was in a position such that when I would get the speed up around 175+, I would get a sufficient negative pressure draw on the vent line which would stop the fuel flow to the carb. A minor relocation of the fuel vent to ensure positive pressure at all speeds is all that was necessary to fix the problem.
BTW, are you going to get your KR to SWRFI? Weather permitting, mine will be there. -Jeff Scott Los Alamos, NM -- "Brian G. Douglas" <bgd...@vvm.com> wrote: Hi Gang! I was out flying for the first time in 2 months (due to job and WX). 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. I have the money but I do like to spend only when I have to. Some times throwing money at a problem works and some times it does not Thanks All! Brian G.
