Hello guys.
I need some help on my '77 F250 CC with a 460, running on propane.
It idles rough when cold and also it has some misses, also when warmed up.
Things that i've done; Checked ignition to be ok, timing set at 10 degr initial
timing (hei ignition)
new plugs.
new wires.
removed and blocked egr valve.
no vacuum leaks.
disabled the choke, not needed for propane.
Thanks William
