When I first put it in the water I step on the gas a couple times and she fires right up and happily idles as low as 600rpm (wont hold that setting in gear though), but I usually set it about 900-1000 which put the idle at 700 in gear. When I'm cruising or wot for a while and come back down to idle, it stalls and wont idle at all. Not sure if it's a temperature issue or not. Also, on long cruises at night the headers glow bright orange, even at part throttle.
I don't want to steer your responses too much, but I'm thinking it's just way too rich or timing is retarded (slipped outer ring on the balancer)
18' v-drive, 396 BBC, +/- 10:1 cr, performer intake, Edelbrock carb (1407) w/mechanical choke, 2" "open" carb spacer, vacuum advance HEI distributer (hooked up to manifold vacuum) timing is set at 36*, plugs gapped at 0.040, 160* thermostat, 049 heads, unknown mechanical cam.
OH! one other thing I notice that the first time I go WOT rpm's go up to about 4700 rpm, but as I stay on it it goes down to about 4300, usually within a few minutes.
So, where do you think I should start? What's your take?
