I tried everything to get rid of it - I have verified the timing, tried tweaking the mixture, verified the float levels, changed the Accelerator Pump Arm Play, changed the Accelerator Pump Cams, and changed the secondary springs (parts at my own expense). Just curious what your resolutions were.

Thanks!
What color dot is on your carb?
