Tuning my chainsaw

[Jacla-17]

Hi all just asking for a bit of advice.

 

 

I’ve got a husqvarna 120 mark II, I know it’s only a small saw but what is the max rpm my chainsaw should be running at? In the manual it says 9000 but after using a tach it was between 12-13k.  
I haven’t touched the carb, after having just modded the muffler i believed I would have to richen the High jet but now I’m unsure what to do. Is the saw running at a safe WOT rpm?

 

im fairly new to chainsaws so sorry if this is an easy question.

cheers 👍

9000rpm is where the saw makes peak power, 12-13k sounds about right without knowing the exact figure.

Ok thanks, was just concerned I could damage the saw running the rpm too high?

12,500 is where it should be, this is an entry level machine which was known as the 236, and 235 before that, straight out of the Poulan factory in the US, as for modding the muffler you will get little to no improvement in power or running.

Ok yes that’s understandable, I bought it cheap and thought I’d have a fun project to do, wasnt aware it would be pointless lol.

so it’s running at the correct speed?

Yes, it is running within acceptable parameters.

 

As ADW has said, by modding the exhaust all you have done is make it a bit lighter.....so every cloud and all that
