MagnaSpark II adjusting

Try 32 degrees @ 3K, and the next lighter spring(allows more /earlier advance). Sounds like not enough timing to me.

Thanks Danny. I did try 32 degrees but not the lighter springs. I will keep stabbing at it, but there is a way to rebuild the MS locking out the centrifugal advance. That might be my next step if I don't get lucky.

@Pat Downs -- ideas or thoughts?

Run the factory springs and 32 degrees total advance. 

  I don’t believe timing had anything to do with your running condition. It sounds like the engine might be lean, what is the jetting in the carbs? Also, when did you buy the distributor? We had a run of coils that had some issues. I can check to see if yours might be one of those

It had been running great prior to putting in the MS II.

So I doubt it is the carb jetting.  They are 40 idfs with the CB rebuild kit that enlarged the venturi a bit (I did not see it at the site , so it may longer be available - forgot what you called it.) I did this about 3 years ago, and I trial and error-ed a few different jet combos. I can look it up - don't remember off hand. But after I got it dialed in, it has been running great for a few years.

I bought the coil and MS about a 6- 8 weeks ago. Serial number on the coil package says - CP - 160/2009

Thanks for taking the time to respond. I appreciate the help.

6-8 weeks ago is our new 2nd generation Magnaspark. This distributor and coil has a higher output. More spark energy can create a lean condition. You might consider trying a bigger main jet and see if things improve.

Does your coil and distributor have a smaller connector on the negative side?

No Pat. Same size connectors for both pos and neg (with lots of printed warnings not to get them backwards).

Pat:  Should we be increasing the gap on the plugs with the hotter coil?  I have a MS II as well (one 1/4” and one 1/8” connector).  I am running W8AP Platinum plugs.

@Pat Downs

I run .028 gap with the Magnaspark. 

MotoCarlo, that is our older coil and it could be the source of your issue. Call me at CB on Monday. I take calls from 12:30-2:30pm. I will send you another coil.

Thanks Pat. I appreciate your attention to this. I will give you a call Monday. Have a great weekend.

Thanks for the gap info, Pat.

0.028" sounds about right for a single coil.

I've been running 0.043" on Megajolt for ten years now. Wasted spark gives a much hotter spark, and my engine really seems to like that gap. BTW, it's the gap that the Ford Escort used that the ignition came from.
