pulse line

[Tony G]

Dan, I am confused, what does the pulse line do if it goes to the carb ? what runs the fuel pump ? is there a fuel pump on carb models I know on my snomobils it ran the fuel pump,,,tg :)

Re: pulse line

The pulse line takes the pulses from rhe crankcase and applies them to the fuel pump diaphragm, these pulses, in turn, cause the fuel pump diaphragm to move back and forth and draw fuel through the check valves in the pump body. This is how the fuel is "pumped"

Re: pulse line

Well I though it was the same as my snomobils but your post on that 717 that said it went to the carb confused me, I was sure it went to the pump like they always have,,,tg :)

Re: pulse line

similar, but your snomobile uses a remote fuel pump (external from the carbs).. Most ski's (not all) have the fuel pump as part of the carb assembly. At any time, you can take off the fuel pump and put on a normal carb plate and run an external..
