Problem 426F 01' No Fuel

11 posts in this topic

I have an 01' 426 i just bought off a buddy that has set for about 2 or so years. I have soaked the carb in cleaner and cleaned the jetts, but the problem i am having is when i turn the fuel on the bowl will not fill up with fuel however if you take a lil compressed air and blow down the fuel line it will fill up but continue to over flow........Now my thinking is i need to recheck the float height and also maybe order a needle valve and valve seat and just be done with this. I bought this bike and its been 3 weeks and still have yet to ride it any help would be much appreciated.

Pull the float needle seat. There is a screen above it, probably fll of debris. Also, the oring may be dried out and cracked. Be sure to install a brand new pilot jet (not just a cleaned old one).

I think you're on the right track. There is a screen built into the needle seat on those, too. It's also possible to assemble the float incorrectly and cause binding.

The seat is retained by a small screw that sits next to it and holds the seat into the carb body by clamping the flange on its edge. It's a small screw, and tight, so make sure your screwdriver fits.

That is at least the same carb model it was supposed to have. I wondered whether it had been changed to a later one with a non-serviceable needle seat.

No. The carb numbers are listed in the service manuals. I might make one up, though.
