Hello, trying to see if anyone can help thru this dilemma.
Some backstory, I have owned a Fcub for ~25 years now, ran it for approx 3 years cutting grass and then parked it in a family member's barn (basic dry storage). Ran and had power but had various electrical issues with charge and discharge of the battery. Retrieved last year and just started working on it this spring.
12v neg conversion, rebuilt wiring harness.
Soaked carb 2x in the "paint can" solvent, rodded out all the holes and orifices except I did not take off the idle tube.
Timed engine by removing #1 spark plug, set by visualizing piston movement and valves stationary +/- 20 deg of the 2nd TDC notch on the crank pulley. Set rotor to this point. Getting healthy spark. Set 1342 order in a clockwise orientation as viewed from the driver's seat.
Here is where I'm stuck. I can crank and crank with more speed than ever before. But I'm getting no cough, no hint of trying to fire.
Some steps I tried...sprayed starting fluid in the air intake tube...reversed the 1342 firing order of wires by 180 deg just in case I did choose the "wrong TDC". Placed a drizzle of marvel mystery oil in all cyls in case valves were sticking.
I am getting fuel to the carb, seems like a reasonable amount out of the steel tube. Verified screen is clear. Opened bottom plug on the carb and a lot runs out followed by same flow as above. Tried choke/no choke/throttle closed, throttle WOT.
I realize I should probably check compression, could attempt the idle tube removal, I have thought about pouring a small amount of fuel in each cyllinder thru the spark plug hole to see if that helps.
Checking in to bounce off ideas and see what suggestions you have, I am mildly frustrated :shock: but not ready to give up Thanks for your time.
