No, not successfully. I tried the Longflo on my Z-S and achieved very
similar results to what you're seeing. Terrible performance and
backfiring thru the carb. Another Spit owner tried the Longflo filter
and saw the same thing.

BTDT. Used the tool, no help, even at max richness. It was suggested
to me that likely the needle would need to be changed to enrichen the
mixture to account for the increased airflow. Me, I put the original
air cleaner back on until the auto-choke loosened up and the carb wanted
to idle too high. That was last fall and during what I consider to be
the peak of primetime driving here in NC and I didn't want any downtime
so I put on a Weber DGV and manifold from British Parts Northwest. That
has solved all my Z-S problems to date. ;^) (Real Soon Now I'm gonna get
the Z-S off the shelf and rebuild and adjust it.)
BTW, now that I'm running the Weber, I've no charcoal cannisters at all.
