Hello all, I'm really frustrated this spring trying to get my 2N to run right after an engine rebuild. Here are the relevant details:
-Major engine rebuild in January completed by a very reputable engine shop with experience on flat heads.
-While I was putting it all back together I decided to replace many engine related components with new at the same time since their age was in question- governor, water pump, carb., fuel strainer, all ignition components including plugs, wires, points, rotor, dist. cap, condenser, coil, ballast resistor, battery, new ignition housing/ cam assy. Did not replace alternator and starter which were already nearly new.
-Just for grins I double checked compression- all cylinders pushing 120 lbs.
- Valve clearances set
-firing order/plug wire/distributor order checked about 10 times.
-Engine hesitates on acceleration and backfires routinely and gets worse/weaker the longer I run it.
The only thing I can think it might be is that the cam and crank gears could be 1 tooth off but I'm not convinced since the problem does wax and wane at least somewhat.
I got so frustrated that I took the tractor to a local tractor shop with an older man who knows these relatively well- thus far he's stumped.
What else should I check?
