my Champion is still sick, chapter II

Hello all, I got back this AM from my weekly Friday AM to Sunday night truck dash across country from Oakland CA to Des Moines & back, survived the Saturdays storm(s) coming home on I-80 ( Snow from Omaha to SLC-how do you guys in the plains states stand it?) and just got done fiddling around with my '55 Champion after I read all of your posts. I placed a timing light on the distributer, checked the timing marks, and they are right on. Reved up the engine to the point that the engine started to break up, looked at the flickering light from the timing light and I saw no sign that the distributer was mis-firing or losing its fire, put my cheap dwell meter on and got about 42-ish degrees and no indication that the dwell was changing though the RPM range or that there was a break up of electrical power. I replaced the condenser in the distributer for the old one, and got no change. I think that I can put the distributer theory to rest.I have gotten very good at pulling and replacing the distributer on this engine. I then took off the air cleaner and noticed that the high speed circut may be at fault. When the engine starts to lose power, the fuel coming out of the high speed nozzle starts to spray eratecly(sp?) and when the engine loses all power as I advance the throttle and is coasting to a stop, the fuel flow stops and then seems to come back on and the engine then barely runs from about 2/3 throttle to wide open thottle. What the heck is gong on? After I take a nap, I'm going to put my spare fuel pump on the engine and see if it makes any differance. If nothing, then I'll go back into the carb using my factory shop manual as my reference. Again.

Best to all, Chris

I ran into an oddball carb fault at the National Meet in Spokane a couple years ago. '50 Champion, Carter WE carb, nearly the same as Chris'. The car would flood while idling, but when under power, would only run well for a few hundred feet, and then starve for fuel. What it turned out to be, was the brass seat assembly for the float needle had backed out about 1.5 turns, so that the float level had been lowered so low the car would hardly run. Enough fuel got around the remaining threads to make it flood out at idle, but under high demand, nowhere near enough could get through. Once I'd discovered it, the fix was easy as pie; just screw the seat in tight again.

In your case, Chris, you might have the same thing happening, or maybe there's some crud blocking the fuel inlet to the carb. IIRC, there's a big hexhead nut on top of the carb, and under that is a screen. Worth checking it.
