So are we going to get some of pics of the muffler mod on the 330?

330 I just remove tube and open stock tiny hole the tube was in, up to deflector size and open the holes in the baffle or remove it all together.

Yep.  Unfortunately I didn't shoot any 'before' or 'in progress' pics.  Here's the 'after' pics that I shot this morning.  Boot spigot on my PP330 cylinder measures out to approximately 1.315".


Here's the parts.  You can see the additional holes I drilled in the diffuser.  Put two holes on the side that had the rectangular holes from the factory (top side) and drilled six more on the blank (bottom) side.  Removed the tube and enlarged the hole that the tube used to pass through.  Hit it with a couple quick coats of high temp BBQ paint.


Set the removed tube in the can to show how much I enlarged the hole.  Could have gone bigger, but it's at about 70-75% or exhaust port area (good enough for me) and my grinding stone was pooping out...


Here you can see the enlarged hole in relation to the deflector.  Yes I see that little bur.  Again....my little dremel stone was about shot...



Here it is mocked up on the cylinder.  Threading the two long bolts in helps get the can lined up while I tighten the short 'inside the can' bolt.  When I assembled it on the saw I reinstalled the spark screen.  I cut in places that require them, and there is ample screen area exposed here (with all those holes under the screen on the diffuser)...................much more screen area than you see on 288XP outlets, so I'm not worried about the screen restricting my little 54cc saw here.  Just noticed that the diffuser is 'upside-down' in the mock up shot (rectangular holes down).  It's now assembled on the saw with the rectangular holes facing up (and "top" stamped on the diffuser facing up).

Did you measure your cylinder where boot goes on?  Not the intake boot outer or inner?  If so I can just measure the 335 cylinder setting here.

I measured the cylinder where the boot fits over it.

Sorry guys I forgot to measure yesterday when I was working in the barn.

Just put PP330,3450,3750 intake boot on my 3500.  The intake spigot/snout on the 2800-3500 is the same size as the PP330.  Boot is perfect fit.  Also changed the HDA49 to a HDA164.  Didnt have a intake bracket for larger carb. so I ground out the smaller one to fit the 164.  It's now snoutless.  I don't think it will be a problem as there is plenty of sealing surface.  Next Jacks order I'll probably get a couple intake brackets PN: 530049465 for larger carbs.  Bought a 365 last night pretty decent runs on a prime.  Don't know why I got 2-3450's a PP330 a 3300 and a 3000 to go through.  Wife is gonna have a fit.  Good news is she will eventually get over it (I hope).  I passed on two new never fueled saws last week a deal on both been kickin my A for not buying them.  My problem is they come here and then they stay.
Shep

Can I have the info on the saws you passed on please!

Easy tiger....
