Question about Woods Porting?

[Andyshine77]

Normally there isn't much room to do on the carb side of the intake. The inside of the cylinder needs to be widened. With most huskys the ring ends are in or near the center of the intake, but some of the newer saws have the ends to the sides of the intake. If this is so you don't want to widen the intake to the point one half of the ring could drop into the port, so take note of the ring end locations. This however is likely not an issue with the 390.

 

[pwoller]

Yes, but are you going to widen the intake? You widen at the bore, then blend it out.

I'll give ya another tip. You may want to start another thread on your 390 since this thread is kinda dead. You'll get more help that was as well.

Good call. I will.

 

[little possum]

Not trying to start stuff, but what was done at the saw shop for the 90$?

And good luck with the porting, I hope to start soon..

Most of the huskies run the rings above the the intake so the rings don't get to the intake even at BDC. I am not sure on some of the newest huskies, but pretty much all the older ones were like that.

Ring end pins can be moved, not the sort of thing found on $90 port jobs or even typical $250 jobs. But when performance is measured on a stop watch then it can be worth while.

Yes. I've never had a problem with ring ends on Husky's.

The 372XPG has one ring end toward the center, and one off to the side of the intake like a Stihl. You have to be careful on that one side.

I'll be answering pm's though, some good folk here.

Well, you can't blame the bannings on this thread, they can however be blamed on the person himself. You have to take responsibility for oneself.



$80?? Seriously? I almost find that hard to believe, unless your good at favors.:monkey:

The president of the CAMEL TOE CLUB™ has spokenumpkin2:

You're such a wuss it's not even funny. I'll pose the same question to you that I posed to troutcherry. How about a build off over at RS and the winner keeps the saws? Let's make it interesting. Brand new saws.

As for you, you need the most attention:hmm3grin2orange:

BS'n on a testing jug that has shotty intake work for $200 is a joke, and to top it all off, to complain about a shop's credibility. I could care less if I get banned, I just wanted to be up front. You fools haven't been angels yourselves.

Now I'm part of the EVIL EMPIRE KLOWN™ crew ready to throw a heist on some stock jugs:smoking:

LATER DAYS!

Ya that one worked out real well for ya didn't it? You only made yourself look like a fool when you challanged troutfisher.

Let me guess the rules the same as when you challanged him? No machine work cause you can't do it? And no chain cause you can't sharpen a chain worth a ****. A stock saw with a decent chain will beat your ported crap with your crap chains.

 

[troutfisher]

Thanks for the kind words Parrisw.

Hi Chevytown13, since you brought up my username I'll respond. I'm glad your porting is going well and you're proud of your work. I wish you all the best - Aric

I'll have to find some better bits for my router before I can enter this competition. Not sure I can compete.:monkey:

The ring pins are inside the port . Offset but still in the port. Widen away?

Ummm? How do you mean inside the port? Any pics?

 

[troutfisher]

If you drop a ring end into the intake port.....K-Boom. I've had rind ends ride over boost ports or finger ports and they run fine, but those ports arn't wide enough to let the ring bulge out into the port. An intake or exhaust port is.

 

[mdavlee]

I think he meant that it won't be on the edge. Here's a picture of a 390 piston showing the ring ends.

I have to throw out a question, as I don't have all the answers. lol

I'm building a 036 and would like to widen the upper transfers toward the intake some. As most of you cats probably know the second (lower) ring end is in this area. My question is this, what about removing this ring???

Yes you can do that, and yes it's been done. I've never done it, so I'm not speaking from experience.

I've not done it before either Will, but have seen it done on other's builds. I'm just looking for a discussion on the subject. Thanks for replying.

Can you run the piston backwards? If the ring ends have support (on the cylinder wall) when flipped around, I say do that instead.

I ported a 66 that upper transfer work was catching ring ends. . . Flipping solved it, and I got to keep my fancy transfer work.

I don't think its a big deal, lots of saws only have 1 ring. Al does it all the time.
