Carbs And Confusion

[ski4]

trying to finish up my ski and i am close. i have always had single carbs on my skis, so plubming duals is foriegn to me sort of. i got a set of stock duals ( thanks Nick) that i am using this year
trying to figure out where to route everything is getting me a tad confused and my shop manual schematics suck

can anyone tell me which is the incoming, out going and pulse fittings?

top is out, middle is pulse, bottom is in.

Not sure if ALL models of carbs have this, but my Mikuni
has little arrows molded into the metal showing
the direction of the flow of fuel, right beside each of the fittings.

i don't recall seeing that but i will look again, may be there but ther is some corrosion that has bubbled the paint in a lot of spots too, i would bet it is under there just cuz that is the luck i usually have

If you are refering to a set of stock 38's, this is how they go. The main in fitting is on the carb with out the throttle linkage.There are a total of three fittings on this carb. The one closest to the cylinder is the pulse fitting, it is on the fuel pump.Connect this one to the case.Then there are two more fittings. One on the bottom and one on top. The one on the bottom is the main in.The main in gets connected from the fuel petcock or the pickup. Then the remaining fitting connects to the fitting on the right side of the other carb with the throttle linkage. Then there is one fitting remaining that is the front most fitting. This is the return line, you connect this to one of the gas tank nipples.

If you have any other questions I will be happy to answer for you.
