try a smaller acelerater pump squrter on the primary (front) side first. Start with a 28. then work on the secondarys. If You can take it to the dragstrip on test & tune night, it wont cost a lot and you'll have unlimited runs. Use you timeslips to tune your squrters. Good luck

If your accelerator pump shot is good,,,check for vaccume advance,,,,,or the lack of it,,,,could be anything from sticky, or holed diaphram,,,advance weights worn and seized.

So if the engine bogs down is it too big a squirter or not big enough. I thought it would be too small a squirter?

[dr_bowtie]

depends....if it's a bog or a flutter....

Bog is usually lean...

fluttering is usually a sign of to much....

Have some one stand/watch from behind to see any signs of black smoke.....that will be a good clue...

lean mixture screws, timing, throttle blades in rite location at idle
