Chainsaw Repair

I wasn't sure where to post this? I am having a hard time getting a straight answer. It is not a Husqvarna only question. I read and watched video's and know everything there is about tuning "by ear", tuning in the wood etc. Now what if you are in a shop with a good tach trying to tune a saw with no wood available to cut into, or say a guy is totally deaf and can not hear the 4 stroking. Is there no way to correctly tune the high speed with a tach only? I can't get a straight answer.

If it were me and was tuning with a tach and couldnt hear.  I would find my model of chainsaw look up max wot rpm. Say it is 13,500. I then would set my carb to 12-12.5K on tach. I rather be little rich then lean side. JMO

You will need to tune it a little less than that. You will find that you will need to tune that saw to 13,000 even for it to sound correctly to you in the wood.

Take note that you should re-tune the saw every time you go to use it and the temperature is significantly different.

Also a saw in a big cut will run leaner after it gets hot than it did in the beginning. So If you are going to do some big wood for the size of the chainsaw, you need to begin a little richer.

Also you can burn up a saw in big wood even with it on the rich side if the chain is too aggressive or big and you push too hard

That sounds about right

I don't like the rev limiters.

Other than replacing the coil with a non limited one, you have to keep the saw rich enough that you know that it is not into the rev limiter. Then lean it out enough to clean up in the wood you are cutting.
