A R E A 51 Husq 365..."Here We Go!"

Crazy Nate, you got me back in here quick!

I kept the piston in it's original position. I don't know how to correctly answer this Nate, but the ring ends run smack in the middle between the finger ported edges.

There is enough meat for this ring ends to ride on.

Gotcha. . . I had to flip around for that 066. The ring end got in the way of my upper transfers "getting better". LOL

Waiting patiently for The Doctor's pictures homes!

I didn't snap pictures of the 066. . . Or the 117.

I was under the gun to get them done. . . I have much more to do though.

Upcoming projects without a deadline:

044

120si

670

038

. . . Those I can do some pics on.

 

[CHEVYTOWN13]

That's quite a line up there. I dig the 044 batting clean up

Be back later with the finished porting. Then it's time for the MEX PORT and some hand porting to blend it. Finally, check the lead on the fuel line and see if that was the problem all along as far as the chain spinning at idle.

 

[blsnelling]

The chain spinning at idle sounds like either an air leak or bad clutch springs. Does the saw not idle down, even with carb adjustments?

 

[CHEVYTOWN13]

I'm following Al's lead and then a pressure test ensues if the lead is not it.

Done with the area and MEX PORT does it again

The final porting.

Time for some big time elbow grease in the form of some wet/dry 600 grit.

Do you polish all the porting? Sounds like a lot of work to me

 

[CHEVYTOWN13]

No, I'm leaving it rough for now. I'm searching for a small abrasive in the form of a sponge like material (dremel sells it) that works great for a finish.

I was referring to the edges of the finger ports. Getting rid of the rough stuff and adding a rounded edge.

Sorry to interrupt, But whats the groves ground up the side of the cylinder and what is there purpose? Im lookin in to porting and im curious?

 

[CHEVYTOWN13]

For more FLOW. It's like a finger porting, but they do not stand on their own in this porting. The other jug will have 6 transfer ports.

I'm fired up to run this modified jug

They're called 'finger-ports'. . . They're made to stuff extra charge into the combustion chamber on the power stroke. They're usually reserved for racing type saws, but a lot of guys put them in work saws too.

LOL we posted at the same time

462 it is.

Nathan, is that bit made out of rubber?

I remember Adam talking about using the rubber bits to either make a bevel or remove transfer material.

Yes, they're a rubber abrasive material, like Cratex.

I bought a bunch of Dremel stuff recently from http://www.mytoolstore.com/dremel/drmindex.html

To be honest, I've done porting from start to finish with one bit. The Dremel 117 bit:

With the exception of using the cutoff wheels to get through the chrome/nikasil.

That 117 bit can be used to hog material, or go with a lighter touch to finish smooth.

how fast do the rubber bits wear metals?

They last okay if you're smart with them. . . They're a blender/smoother and not a remover per se.

I've used them quite a bit on firearms etc (not chainsaws) and they are excellent - you're right, they'll pretty well only get rid of the grinder marks and won't remove much material at all.
