<VV> Help - Engine runs worse than before!

[Harry Yarnell]

Can't remember if the secondary return is tied to ground, or to the + term.
At any rate, it is high resistance, but certainly under 10k. And yes, if it
was open, there'd be no spark.
Reading coil resistance is somewhat like rearranging the deckchairs on the
Titanic. Best is a scope; lacking that, swap the coil.
I don't think that's your problem (could be, though).

Everything seemed ok prior to your cleaning of the carbs. That's where I'd
start.

Thanks for your response Harry.  I also checked coil resistance...about 1
ohm primary, and no response from the meter on the secondary winding.  Which
means there is no electrical connection at all.  Could that be a problem?
Should the engine run at all?


Isn't there supposed to be some resistance on the meter with the secondary
winding?

Wish I had a second set of carbs but I don't.  I just may end up getting a
rebuilt set.

Thanks again...Bill 66 Monza 110 PG
