Long Post:
Bought a 66Falcon SW 2 months ago and found out this thing has been 'beefed-up' with the Clifford performance kit. Things I found:
1: the OE 200ci block to have a 3.91 stroke, 250ci crank.
2: it had an LOM distributor. Replaced it.
3: it was using an OE-style mechanical fuel pump. Changed to an electric (solenoid, not rotary vane). Pump is an Airtex which puts out 32GPH @ 7-9psi.
4: it wouldn't idle at all, but ran off idle and sounded 'fat'. I've since learned on the Weber 38 the sound actually indicates a lean condition. Couldn't do anything/adjustments at the recommended starting points A: Idle Speed 1/2 turn in and B: Idle Mixture Screws 1 turn out. Did eventually achieve idle but the number of turns indicated lean, got Jet Kit.
5: the biggest confusion I have is the FLOAT SETTING, . Several different answers from several different sources, Clifford, Redline, Jeep Forum, and here. Drawings showing bottom of float 35mm-51mm from cover (no Gasket); Drawing showing 18mm to top of float parallel to top cover with gasket and 2mm of needle travel; another said 17-18mm and 22-23mm down position; All measurements were done without depressing the ball/spring in the needle. I recently had it idling with the float at 17.5mm , but read so much about how it should be 18mm I changed it and now fuel isn't filling the bowl. Pressure regulated at 3psi, then 4psi, and now 4.5psi. Today I bump it to 5psi (at 6psi it was getting into the throttle bores).
6: had to modify the float as offsetting the arm to attain 18mm it would hang up the Power Valve Screw.
Jetting as received:
Main Jet: 145
Idle Jet: 45 (changed to 50)
Emulsion Tube: F-50
Air Corrector Jet:170
Accelerator Pump Jet:70
Timing set at 16* (remanufactured non-LOM).
Anyone have a photo of how the float arm is supposed to be bent to attain the 18mm measurement?
Thanks, RodC
