Pioneer NU-17 Parts

[laharview]

Newbie here,

I have a Pioneer NU-17 that my Father bought new (1962, 1963??) and I ran as a kid 45 odd years ago. She is S/N 185427. Still has great compression and we mothballed her empty around 1980. Wanting to here her run again for old times sake.

Looking for Primer Diaphragm, gasket, etc. Upon inspection this is the only part that has failed. It appears the the 400, 450, and 500 used the same one.

Also any information on the year of manufacture.

Thanks,
Mike

Harley, the NU17 uses a separate fuel primer pump, they are scarce as hen`s teeth. Many of the older IEL and Pioneer chainsaws used these pumps instead of a choke.

Thanks all. Yes it is separate from the carb and acts as a choke. Would like to find a breakdown of S/N by year if it exists. My truck is a 1962 and that would be cool.

I have 5 running NU17`s and rebuilt the primers on all of them. I have not found any more of the pump diaphragms for more than 5 years, likely still some out there somewhere but not easily found.

Hey pioneerguy600, is there a work around for the part?

Not for the original metal pump but a few guys have jury rigged primer bulbs from saws like Poulans that have those bubble type primers.

The two parts in there that go bad were made from a rubber compound that old fuel mix just dissolve, usually just black goo left of them by now.
