Leaky welch plug would cause the issue as would a high needle that seats on the spring before the orifice.  Other than that id suspect the fanwheel /coil issue

Did new carb and new coil.

Tore it down and going to go through it.

Never pulled flywheel. But did check magnets for pull.

What if fly slipped?

I would check the inlet needle taper on the new carb and compare to the one in the tillotson. I remember back on the 394 I did the inlet needle in the k10-wj kit had a second taper. Pulled it out a used the one from a k15 kit with a single taper and helped to fix the over rich problem.

Back together today. Put new ring, redneck fuel line using old molded grommets etc.  Bot new carb bolts as the heads have been wollard out over the years.

Reason for new ring even though pulled 140psi.  Ring wear was noticeable compared to the new one and it seemed like old ring had lost tension.  Just mt WAG

Maybe ring FLUTTER was what I was hearing even when H was all the way in? Is this possible?

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.

If you have the 234 in the box just measure the throttle bore with your calipers?

I was thinking you had the bigger carb on the saw?

Me and Jim was talking about the blow by on this.
If I remember right I swear I could tell a area in the ring where it was thinner too.

The area behind ring was wet and whole ring blacked. Ring had felt like it had lost tension IMO too.

Anyone heard of this before and causing the problem I was seeing?
