Do new saws need running in?

[spudulike]

A new saw will gain compression once the piston and rings have bedded in to the cylinder through friction and wear, that will take a few tanks to happen.

 

Many saw manufacturers will leave the low screw a bit lean to meet emission laws, bogging in the mid range is a classic sign of this and if you turn the L screw anticlockwise by 1/4 turn it may help but avoid just twiddling the screws with no finesse - turn the H screw in to far and you can kiss your piston goodbye - see how the L screw goes, if the saw is struggling to hit the high revs when revved freestanding, if it smokes a bit then it may be down to the H screw settings but also, these modern saws can have limited coils giving a similar effect - the MS201 and MS150 are two that sound flat at the top end due to this so beware - a tach is the best way to tune these saws IMO as it will go loopy when the rev limiter is hit!

I wish shops would PDI saws properly. There's only a handful in the whole southwest of england I would trust to do it properly; 1) Radmore & Tucker (Kevin), 2) E Buckland & Sons, a couple others.

 

The likes of Abbey haven't got a flippin clue.

Cheers spud, will give it a go once I have got the right tool. Handily they don't supply the correct tool to adjust the carb even though it tells you how to do it in the manual!

Yeah, it came from abby. I'm not sure how they would have set it up if needed as they couldn't have run the saw as there was no trace of fluids in it!

Cheers mate! It worth changing then? I mostly do small trees or use the echo for trimming fence post tops to the right height.
