marine carbs have the J shaped bowl vents.. so any flooding goes into the carb not over the side and into the bilge..
marine carbs also have grooved throttle shafts.. so there is less chance of fuel dribbling out the ends of the baseplate and pooling on the manifold. .
$792 in Australian money ??? About $500 here I think.
Don't see #3217 on that chart... check to see if throttle plate and venturi diameters are same as on that chart... some of those marine 600-looking carb.s are actually 750's!
Marine carburetors are set up richer than street carbs and typically richer than performance carbs.
Marine engines are always loaded - there is no such thing "cruise" like when you are on the freeway. Cruise in a boat is pushing a lot of water and the engine is under a load. The carburetors are set up for that load. The jets are bigger, the power valve has larger ports and the PVCR is usually larger than an equivalent street carb. I have never tried to tune a marine carb for the street but I have modified a few performance carbs for boats. I think you have your work cut out for you on this one.
hmm... that sounds interesting.. might make far better carbs for LSR racing and the monster mile.. i don't have a marine carb to take apart.. but i might be checking that chart also.. since we now have a number to compare.
I have decided once again thanks to you guys that this is not the carb for me I think it would be too much of a hassle for me and like Eric said it just looks like hell also lol. Found a decent looking 4160 series on eBay for $80 I think I may pick up.
I don't believe I would buy a used carburetor unless I could install it on my truck to see if it works with no problems. I want my vehicle to start as soon as I turn the key. So as important as a carburetor is I would have to buy one new.
