 No aluminum tags. Dells are from JHPS and tuned for lower speed drivability which is my goal. He has sold multiple similar setups with no problem. So trying to figure out why I am special. Compression:
1 110
2 110
3 112
4 115,
Fresh gas, gas filter clear, static at 12 degrees BTDC and advances. Changed out points carb for electronic distributor. Little stronger but still missing on the road.

10 grams floats set at 16.5mm with gasket at vertical just touching the needle valve. Gas pressure at 6psi.

Verified jets, emulsion. idle screw same as spec'd. Replaced prior "dark" sparkplugs. New ones are very light indicating lean mix.

Have to go to idle mixture screws 4 turns out from seat to get smooth idle. Revs up smooth but when driving starts missing bad at around 2K rpm even at cruise so appears not to be accelerator jets. With choke on, still runs rough at 2K rpm.
