Holley 850 CFM Carb it's a 4150 series that works great it is a Double pumper mechanical secondaries with No choke horn. .. comes with Fuel rail and oil filled gauge.. Carb with fuel line 250.00 .... was last ran about 6 months ago and worked perfect. was going Bigger engine and bought a 1150 Dominator.. 530-333-1047 Bill .. Located near Sacramento , Ca.
i will check in a few. i don't know for sure if it has the J tubes .. it does come with the Spark arrestor for the scoop as well i left that part out..
Was gone all day and can't log in on my cell phone. It is a 4781 Holley carb with the choke removed. it has normal tubes not J-tubes in it.. Here is actual picture of it..
mine does have the Spark arrestor for marine application for the Scoop. just the J tubes are what would make it really a marine carb , you would have to remove the Scoop/Spark arrestor to notice the j-tubes ..
as far as i know J-tubes and a spark arrestor is all that's required in an enclosed engine bay in a boat.. and like Jocko said the j-tubes are easy swap and cheap.. i have the spark arrestor that goes with scoop. carb alone i'd do for 250 with fual rail..
I don't know that a crossover vent hose on the tubes is legal, but it sure makes the fuel have to travel a bunch further before it drops into the carb. simple piece of fuel line connecting the two tubes, with a hole cut into it up top, facing down of course.
