Off idle sneeze
 

Been having a issue with the ZL-1 in my Malibu. ANything under 1500 RPM anb a good stab of the throttle will result in a misfire thru the carb. I need to gently roll out of the hole then stab the throttle. Timing is 19 initial, 18 in the dist. ALso will sneeze when you slow down and then get back into the throttle easy. Any ideas?? already have installed new plugs, new oil, Eric just did my carb, MSD dist new wires..HELP!!

thanks

ALbert;

I never heard back from you on Friday. What did you come up with on the trim screws?

Call me tomorrow afternoon and I'll try to help you get this thing dialed in.
