 Was talking with Cliff about this a while back and he had a 5 cube that he thought had carb or ignition issues and it turned out to be a ring that barely nicked a port and was hard to see...

Good info. Right where I was at and nothing new fixed it.

Thats why I pulled it down to go piece by piece.  I would have never thought of a ring causing this. But it did.

Rednecking the molded 1 piece oem fuel line in these with tygon line.

I just cut the grommet off the tank area area and then installed the tygon line through tank gromment. Then through the the carb area seal.

Just comparing carbs

Tillotson HS260 to HS234


260
Venturi 11/16"-17.5 MM

Throttle Bore 20.64 mm on  a 260a race carb

234
Venturi
11/16"-17.5 MM

So what is the difference in these 2 carbs?  I cant find anything on throttle bore on 234.


How about the interface vs. intake, impulse, choke, throttle, etc?

JFYI those aftermarket replacement carb bolts were perfect replacements. 268 61 272 are on list. Any other saws they work with?

Cant remember if I told this.

While I was rebuilding a 272 for a friend. He was thinking he might want me to muffler mod it.

Well after she was all together and many brews later still hmm hawing about muffler mod. I explained how open the 272 muffler already was and would just be opening the exit and it will get louder and carb adjustment. Explained 272 will not see gains that some of the choked up saws will see like a echo or stihl 290-390 saws do. 272 already breathes good IMO.

Well I finally had a idea. I took my stock muffler 445 and my muffler modded 505 to the back testing log. I let him make cuts with both. Then ask him what he wants to cut with for hours.

272 still has stock muffler. ;)

The redneck tygon fuel line  in place of the molded line above.

I just reuse the grommets and tygon. no drilling for any I have done so far.

I used your idea just the other with a small change.   I used a piece of brass tubing that I pushed through like you did and then attached the fuel line to both sides of the brass tubing.   You can get the brass tubing at any hobby shop and it comes in all different sizes.   The brass tubing has no give and will not compress when pushed through a grommet and with fuel line on both ends it stays in place.
PP 505, 475, 445.
