375xp-51.4mm

[SawTroll]

The venturi on the 390 is a little over 17mm from some other posts I found.

As I said, the nominal venturies are 17.46 for the Walbro, and 17.5 for the Tilly - basically the same as the HD-12 (17.46).

What they can be opened to may vary though.

According to 2010 IPLs, the 395 carb also has a 17.46mm venturi, and the 3120 a much larger 22.82mm.

Got the uppers mostly done tonight, might need a little more work. Was a little frustrating doing the uppers, haven't done it in a while.

That's what you get for taking all that time off. umpkin2:

Ya I know. My bad!

Its nice, expensive, and not that easy to use.

Ya, I've done that. This right angle piece chatters like a MOFO. to work the best you need left hand and right hand bits and a reversing Fordome.

I switched to green silicon carbide stones for the uppers. Smooth as silk, and still cut good.

Hopefully you did the "middle" as well!

Actually, I think I got the last ones from lowes. Here is some I just found though....

Oh ok, they are stones? I think I may have a few in my Dremel kit. I'll give them a try.

The interior of the transfers - I hope you are joking!

I wasn't joking, I didn't know what you meant! Yes of course I do. That would be like wiping your ass before you take a crap.

They work fantastic, but wear out pretty quick. Be sure to have several spares.

Ok, thanks. I'll get some for the next saw. I really can't stand the chatter. Really bothers me, espicially after spending $300 on that dam hand piece. And now its making noise!!! GRRRRR

Everybody I know that has the cc specialties hand piece says theirs chatters. Mine it still nice and tight, of course I don't ever have time to use mine, so that's probably a big factor. Lol.

The stones don't chatter, but don't cut as fast either...

 

[LegDeLimber]

The green silicon carbides have a faster wear rate
theory on it is that keeps a fresh surface with more sharp
grains being exposed as it wears away
Also makes them more aggressive/faster when honing.

from what i can recall, they definitely had a different feel from harder stones
in a die grinder.

but interestingly it's also the stone you use for grinding carbides
and your tungsten for your tig welding.
Same therory on that breakdown and fresh grain exposure
and yes, grinding axially vs radially does make a difference
in how well you can control the arc.

My handpiece made noise after porting 3 cylinders, it doesn't do it all the time??? Wierd. I wasn't happy with their response, they said I could be using it wrong, and may not be covered under warranty, I never sent it in.

Not everyone that is porting saws does it.
