My son wanted a sled project, so he bought a $100 Arctic Cat Jag 3000 F/C.
We:
Pulled the plugs, checked compression, GOOD.
Verified spark, GOOD.
Pulled the carb, disassembed and cleaned in a can of berryman's, GOOD.
Cleaned fuel tank, GOOD.
Tried to get it to pump fuel, but it wouldn't.
So, pulled the fuel pump, was gummed up.
Disassembled the pump and dropped into the can of berryman's.
Rebuilt with new diaphram.
Still won't pump fuel.
Replaced impulse line with the blue snowmobile tygon fuel line, no change.
Removed carb fuel line to see if needle/seat stuck, no change.
Tried a new piece of fuel supply line directly into the tank (bypassing the in-tank line), no change.
I took apart the pump and it looks right, everything is clean, and the diaphrams line up correctly (I am fairly certain).
Tried hooking up my vacuum gauge to the impulse line, needle never moved.
I am at a loss, what else can I check?
Thank you,
