The tach on my spit tends to intermittently lurch and jump about 500-1000 rpm above the actual rpm. It's much more prevalent at higher rpms.
Here's what I got:
Flamethrower coil
Pertronix ignitor
Otherwise, stock
Idle is a bit rough as well...was that way with the Stromberg, and is still that way with the single Weber 40DCOE. You can see the steering wheel shaking, even at 1000 rpm. Car runs good on the road, lots of pep.
Could this be indicative of a bad ignitor module? Could it be a bad tach?
