72 Series 3 stalling under load - SOLVED!
Hello Everyone I got a problem that has me stumped. Hopefully the collective knowledge here can help sort me out!
Darla - My 1972 Series 3 2.25 Petro engine
Started about a month ago....
While under load (climbing a hill or on the highway) I begin to lose power and have actually stalled a few times.
If I'm on the highway doing approx 50mph I can curise along just fine until I come to any sort of hill to climb. On the hill Darla will begin to rock back and firth (sometimes violently) and begin to lose power. I have to decelerate and hope up to get to the top of the hill before it stalls. Yikes!
Starts and idles fine both cold and hot. I can cruise around town with almost no problems.
Since the problem started I have done the following:
Rebuilt the carb (Zenith)
Drained the fuel tank
Blew down the fuel lines
Cleaned the fuel pump bowl
Replaced the fuel filter
Rebuilt the fuel pump (didn't need to)
Checked timing (good with 6 degrees advance) @approx 950rpm
Back in May approx 2000 miles ago
Full tune up including plugs, timing adjustment, compression check, fluids, filters, ext...
I'm feeling like this might be related to the distributor, but I just don't know. Back in 2014 I rebuilt the distributor added electronic ignition, new coil and plug wires.
Any help would be appreciated.
