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.
 
Could you have a uneven fire new dist for a even fire engine.

I agree with Duner. Those came two ways. Look for the model letters. TJD fires 180 apart in two revolutions. THD fires one on each revolution. Distributor or mag will reflect that.
 
I agree also. Even the four cylinder Wisconsin engines had odd fire and even fire. Learned that when a guy dumped a couple engines for parts. I was robbing valve parts going down firing order when adjusting them. My V6 Dodge Dakota is an odd fire also due to the 90 degree block where as a even fire V6 uses a 60 degree V block.

His is the TJD engine
Ultimately the problem isn't mine although the distributor made me a little dizzy.

Update on engine trouble. We moved the distributor(dizzy) 180 degrees and retimed it and it ran better than before the dizzy change but had to retard the timing to 20 deg after tdc and also it ran better with the alternator disconnected. The alternator was charging anyway. I have no answers to what the problem was initially so I'm out.
