1952 3100 with 1954 235 engine Head - 3701887 GM7 --CON 12 -- G73 Block -- 0030392F54Y --CON -- K163
Engine was running fine until about a month ago. Would run great one day, horrible the next. Here is what I've done following suggestions from a previous post and reading other posts....
Rebuilt carb (actually have tried 2 - both rebuilt no change) Timing is about 2 degrees before BB - that gave me the highest vacuum New cap, rotor, condenser, wires, spark plugs, coil, battery, battery cable, wire to coil, wire to distributor Both the old and the new plugs are black and sooty Dwell reading 38 Vacuum gauge reading about 20 Engine compression after running engine about 2 min - 132,136,138,136,134,135 Adjust valves after engine running for 15-20 minutes Truck is still 6 volt and has had both the starter and generator rebuilt in last 6 months. Wires to distributor checked to be in proper place. Distributor checked to make sure rotor was pointing at 1 at TDC Distributor does turn / advance when given throttle All gaps checked, then checked again, and again....
If you try to drive it it begins to cough, chug, and popcorn and power is gone. If you rev it and hold the RPM's to 1500-2000 - it shakes and feels like you are forcing it to run and will finally backfire out the tailpipe. I'm hunting for someone local to take it to - but would love any and all input!
