Ms461 carb reset?

[Ledburyjosh]

I have just been given a ms461. Which is working sub maximal. I had a look through the exhaust port and it seems OK in there. So filter and carb arr the obvious things to check.

 

It has had the limiter caps removed on the carb previously.

 

What is the process for reseting the carb with limiter caps?

 

Whilst fiddling I also noticed the L adjuster when tweaking kind of springs back a tiny bit, so you turn it say anticlockwise the it will return clockwise a tiny amount. Is that normal?

Just set both screws to one turn out from fully in and see how that goes. In my experience, the H screw on a nicely run in 461 needs to be closer to 1.5 turns out to keep the revs where they should be.

The springing back is more likely due to the sealing O ring. It may be better if you lightly lube the screws but it shouldn't matter to the running of the saw if minimal.
