IEL-Pioneer thread

Jim got any idea what the part number you are looking for is?

No, I’m trying to help another fellow out.

Looking at the IPL it seems the NU-17 doesn't have a choke but sort of a primer pump instead.
Wouldn't be the only Pioneer without choke, 1150 has a similar setup.

The picture he sent made it look like a yellow knob. Is it a pump? He doesn’t speak perfect english so we may have miscommunicated (?).

I was looking at an NU-17 today, mine has a primer button. I have a couple of parts saws but neither one still has the primer.

Yes the NU-17 has a primer pump,426815, that induces fuel straight into the carb throat ,rebuilding the pump is about impossible without the correct push diaphragm, the check valves are easy to make. I have rebuilt many of them throughout the years but finding diaphragms is the trick these days. The best alternative is to convert the primer setup to the easily available bubble primer bulbs like used on many smaller consumer saws, all that is needed is a squirt of fuel into the carb bore to get them started, same saw as the Pioneer 450-550. The yellow primer pump button, 426830, is usually busted off any old used saw so a NOS one would be tougher tracking one down.

Looks like this is it? Thanks @Basher for the part number
