Likely an air leak.^^^^^^^^, coil won’t make it rev at half throttle.

So whats the best was to check these things?

I'd start with pulling the muffler and carb to inspect both sides of the piston. If it's good then do a compression test. If both check out then either put a new kit in the carb or upgrade to the newer one.

I pulled muffler and carb before running it. Seems to be worn but no gouges or anything. I cant see the machine marks anymore though...and where is a good place to get a mighty vac?

As this thread is active again, I feel free to add more accurate info on that matter:
The larger (17.5 mm) carb came early 1991, at the same time as the one-piece coil, larger muffler and more. This also meant that the case was slightly different, as was the top cover. The top cover still was gray though = there are two different gray top covers for the 61 out there, that doesn't interchange.
The top cover didn't become orange before Sept 1993 or so.
Regarding TOMOS made 61's, the story may be different.
I really like my Husky 61. My hat is off to anyone who tries to keep theirs going. I rebuilt this one three years ago, and it is a dandy chainsaw:

I have a few 61's with a Walbro ws17B on them seems common in my area and of course most of the rest of them in this area have tilson HS 163 A's I have only seen a couple with the HS 254s and the WJ-125-1. One come through my shop a few months ago the guy claimed he bought it brand new and it had never been worked on yet it had an HS - 160A carburetor on it and I believe they were only on the 272's
