How To Tune a Chainsaw

Most people don't realize that an improperly tuned chainsaw can overheat and melt its own piston. Here are two easy ways to tune your chainsaw correctly.

Tachometer:
I added my own alligator clip.

Lou, that is the simplest but most complete chainsaw tuning video I've ever seen. Great job! Those tachs make much easier to do!

Thanks for the tips . Either that is an incredibly hard log or your chain is mighty dull.

I ran across a Stihl 021 MS250 and it doesn't have any adjustment on the high speed jet.

May want to mention limited vs unlimited coils and how a limited coil when the RPMs hit the limit it sounds like 4 cycle (Flutter). Have to be careful to not assume a limited coil is on flutter if it's on the limiter of the coil... .could be getting not enough fuel in that scenario. You can put the saw into wood and tune it to flutter while under load in the wood and well below the coil limit and then lean it until you get roar in the wood but well below the coil rpm limit. I always try to run unlimited coils as it makes tuning much easier (by ear and with a tach... no worries about the limit!)

Don't leave that old harbor freight screwdriver out in the sun. On a hot day they turn into pudding...

My husky ms240 has a wet spark arrestor cover. I suspect low or high jet is set to lean?

Excellent video. Good quality, concise content. What are you using for exhaust hose? Is there a far end fan?

[FarmerBrad]

Can you show generator running/rebuild carbs

[alaskauncut]

Good video! The sound of my saw changes while I'm cutting. It will sound smooth and the gargle or flutter and then go back to smooth sounding as I'm cutting. Is it getting to much fuel? Im a newbie and have an Stihl MS 181 c. Im weary about about fiddling around with trying to tun it but may give it a go

Why does the tach in your video look different than the one you put in the link?

Never thought to mark the screwdriver…… nice
