It might be the fuel injection path the fuel mix takes, but IDK for sure. The injector does aim the fuel mix right at the ramp as it mixes with the incoming air. Might be the difference between a few hundred hours of run time vs several hundred hours of run time. Won't know till you try. What is...

This is from the shop manual. I recall when I was in Germany for the intro of this saw that we were told the scavenging ramp was there to deflect the fuel oil mix up into the small end needle bearing, and prototypes without it had bearing failure with low run time. So the risk you take by...

It is interesting how many versions Pioneer made from that one design format. I assume the differences were in CC's? Cool that you still have a working primer. I looked at the exploded view and it looks like the diaphragm is cone shaped and would be difficult to duplicate. Here is what is left...

Well Basher, the NU 17 saga ends with it kicking my butt. As I went further into these two saws to try to make one good one things just started looking worse and worse. As I said before, they were used in training schools which is hard on them, with different people tearing them down and trying...

That thought crossed my mind but then I thought, "nooo they wouldn't do that!" This has been fun... Thanks Basher

Help Please! NU 17 bar studs The studs do not go through to the oil tank: They will not unscrew with a stud grip tool, or vice grips, so I used the blue tipped crescent to warm one up: Then let it heat soak a bit, and nothing. Three heat soak cycles and still nothing. Am I doing this wrong by...

I tried to send Jason a MS 361 deco plug cover a while back, put it in a padded envelope and mailed it from here in N FL to him in VA, a couple of bucks postage and he never got it. So I sent him another one, with a tracking number, now it is 8 bucks and he got it right away. So if Av wants this...

Mark, I saw the big cutter in another post, way cool. Amazing what was made over the years. And that saw is a beauty. Here is the part that started this discussion regarding the NU 17: Slight crack but some epoxy on the underside would solve that. I checked out the other saw I have and the...

I have been talking to Av8or3 about a spare NU 17 I have but now I am not sure if I want to break it down and I am afraid it would cost a lot to send the whole saw over to EU, so lets keep looking in case someone else finds one while I make up my mind. Great that we can all chime in with info...

This grinder was given to me by a dealer in New Jersey whose Dad started the business back in the '60s and bought it new in the '70s sometime. It had been out of service and got knocked off the bench and broke one of the pivot ears off. You can see a little piece of red metal on the right and...

Well you are right. The old USG I have, made in the 70's, is true at the zero setting.

Sorry, I got busy on another project and forgot to check. So you are correct, on the zero scale it is not square with the sliding plate the swivel rest sits on. So I adjusted the head until it was square and here is the reading on the scale: So it looks like about 3 degrees off.

I looked in my box of 361 spares and I think this is the plug you want. Send me your address in a private message and I will mail it to you. Just the plug, not the whole shroud!

Squish, that looks great. You do what works for your situation, and being able to store the grinder away when not needed saves room. My grinder station is on wheels but still takes up several square feet of floor no matter where it sits.

Thanks Duane, I have plenty of chaos, I just don't post pics of it! I have scratcher chain on a BLK, but that is the only example I have, and Holtec is in the USA but the chain is sold direct to them, not through the dealer network.
