Do I mention that I've tried hogging the transfers out before?
This jug is from a saw that hung a ring......:msp_unsure:

Now the exhaust port is another place that I spend some serious time on the 372. Again....I've tried a bunch of different stuff.......but the exhaust height at 100 - 99 degrees from TDC seems to work reall well on the 372 when it's main propose is to pull a work chain.
There still has to be a bevel and some polish here. I use a 1/4" diameter diamond stone in my RT angle to do the bevel.....and varying grades of Scotchbrite for the polish on the port edges.

Whats up with the goo in the right-hand jug? Some of that technoplate whatever?

Sorta tough to see but there's a step in the floor of this outlet. Terry Landrum first showed me this in an XPW he had......that saw was a bad dude.
I've done it with and without this step.......but I think it makes enough difference to be worth the time.....

I sure don't know everything, and would love the hear opinions, ideas, mild criticism.
You are humble, admit that there is more to learn, and have such a level headed approach to your builds and the way that you present them on AS- I think that is a good part of the reason you are well respected here IMO. I don't ever remember you carrying a "better than thou attitude", or demeaning anyone looking to learn. I feel like I have learned quite a bit from you, just from reading and watching your work intently in these build threads. I think many of us have. I'm not butt kissin' here, but I think there are more than a couple reasons guys here are keeping you working around the clock, and your attitude is probably #1.

The transfers I think are where you can either build a saw that has that WOW factor or one that is just OK.......on the 51.4 mm XPW jug I set them at 122 degrees from TDC for a BD time of 22 degrees.

On the intake I let the lowering of the cylinder determine the duration. The way I cut the squish and lower the jug I end up at 80 - 82 degrees. I don't do a lot of widening on the intake on this model because I would rather not add any more time/area to the port.

I've yet to find a BB 660 jug that I like Sam.
I gotta sign off for a bit........be back later.

30 users........ finally something worth reading.
This is something I've been wondering so I'll jump on this hijack. Is porting and aftermarket jug generally not a good idea? I seem to remember reading that somewhere but don't remember where. Is it a waste of time? By the way, repped for a good thread and something worth reading lately.

Randy I don't know if this is how you did the 375 I bought from you but it sure cuts. It's been so hot I've only got a couple tanks through it but its one hell of a strong saw. Thank You.

Depends on the kit. I've got a ported Meteor kit on my 372 done by Randy and its a strong work saw. 24" with an 8 pin all day in hardwood.
Back on topic to see how he chews on cylinders.....

that about sums it up.
Plus he has the coolest username/ sticker.:msp_wink:Maybe you should be pricing your port work by the pound. Just sayin.
