A friend of mine came over with his j20 ditch witch to trench a 4" water line for me. In the mean time while it was here he had gotten a electronic ignition dizzy for it so we put it in as instructed. It hasn't ran correctly since. The reason for upgrading was lack of reasonably priced parts.
The new distributor looks exactly like the old one with 2 sparkplug connections 90 degrees apart. It is a strange setup and we had the front coveroff for timing and it is spot on. It actually runs better with no. 2 plug wire off like they are fighting one and another. Our resident expert came over and moved the electronic pickup around(the one that slips over the old cam lobes in the dizzy). The dizzy turns at half speed of the engine and it turns 270 deg with no rotor contact and then 90 deg for both plugs which is 180 deg for engine. My question is how is this possible to run with some efficieny? Our expert said it has big counterweights on the crankshaft.
The engine has descent compression.
