Oregon 90sg. If your jig is for 3/8lp then it should work.

That little saw is a runner. I should use it more...

I know that it's a computer controlled carb. My late question was in regards to how you know its getting all the fuel it needs. I'm just trying to see why gutting the strato's does/doesn't work. Why won't a more evenly mixed fresh charge & a less restrictive intake not result in more power...

As demonstrated by the intact strato'd motor still being able to misfire/4-stroke?

Then would you have more fuel in the fresh charge with them gutted?

Is all the fresh air purged from the cylinder with the strato's intact?

Yes. No.

Would the increase in air flow from the rest of the port job negate some/all of that?

If you remove the needles you can grind the limiting ledges off the collars and reassemble.

It's an issue with mine as well. Have you tried some grease around the filter horn? Seems to help.

So let's see your Google fu pull up what 52c or l is. :popcorn2:

Pretty worthless in this instance.

Have you tried that lately? All Google pulls up is worthless adds for me. 52c is .404 .063 gauge chipper & 52l is .404 .063 chisel

I'd guess it's a quality control issue. Sharpening specks have them all at .025

Clipped heal is how I've learned it.

So you know a 390/95 isn't making as much or more power at 10,2 as the 372? Have you tested these saws with the same bar & chain in small wood? Or are you just repeating something you read on the internet? Why does it cut faster? Don't leave.

084 vs a 390 about the same cc gap no?

So you like loosing?
