running the dellorto carb setup and it started missing today at idle. I changed the plugs, ignitors, cap, rotor, wires, checked the timing.

when i pull wires one by one each one makes the coil arc to the ground except when i pull L1. When i pull L1 and keep it close it has spark, when i pull it away it doesn;t make the coil spark, but rather makes an arcing inside the distributer.......

with L1 connected and supposedly firing (i have spark) and i pull T1, the engine almost dies...

what would make me have spark on L1 but not quite enough?

If i retard the timing it idles great and drives like crap.

Thanks in advance.

 

Well the only common thing is the cap/rotor/plug wire. If T1 is firing good and hot, then the mag trigger, igniter, coil, coil wire are good. Nothing else pops to my mind.

 

Got it figured out.....carb was running so rich it actualy fouled out hte brand new plug within secinds of cranking it......
