Hahaha.. NOPE. Just noticed this..

To toot my own horn as is popular now... Have run thousands of saws in different brands models and sizes. I ran more than 100 in each model of the common saws sold a lot here like 346, 357, 372 etc. Have now 850 different saws in collection, 75 brands, 1500 more in parts and doubles of all...

So this video is a good example of what to do? Porting and wrenching saws is all fun and entertaining. But to know what do what and how to do what and were you need a lot of experience and testing. To know how a saw model run you need an average performance result of several saws of same model...

Well to show a video is one thing. To run the saw and make money from it is a completely different ball game. Racing saws is fun, building racing saws is fun too but not the same as work saws. You can toot your horn all you want and be as good as ever but if the saws perform, they speak for you...

100 years saw wrenching.. Hmmm Last time I met the two closest dealers here we sat talked about the saws and had around 200 years between us and I am the young padowan as well as the guy to my right that has been wrenching saws since 50's. Well, then you know the differences in the engines! How...

Not if its been wrenched on... No matter how little you do it it woids warranty.

I know saws built as standard saws by LARGE scale builders with unlimited resourses like Stihl, Husqvarna That went kaboom under less than 8 hrs....

I know what porting is and have played a bit with this as well. But as you increase the power, you decrease the hrs. Not a problem for most. Another issue is warranty. You need to keep it valid on new saws today... You can't compare bikes and chainsaws. No one runs a bike engine 8hrs a day 300...

You need fuel to generate power. Grab a can of air and measure how much torque you get from it... Decreasing compression space is in my head just dumb. Better to fill it up with suff that can generate power. Fuel is not enough you need air as well or rather oxygen, but in an appropriate mix it...

If you want good emissions high rpm's is not the way to go. We known this for 100 years. Faster revs give less complete combustion. So they run them leaner and leaner, cat's in muffler and very good fuel and ignition systems to help get rpm's up more. Why? They don't last longer or run...

There is no need for high rpm's above 12 000. Put another cog on the wheel or two instead if you need chainspeeds higher than 21m/sek.

They run lean. Its not the fresh air in cylinder that cause issues as I see it its the lack of fuel/oil mix in crankcase. Its like punching a 6mm hole in case... Here we fight air leaks for decades and they think its a bright idea to design it in the saws? It did not work in 1924 when Rinco had...

Saws today run hotter, with more rpms and less runtime/saw. If you look at the saws made in 80's and early 90's they had 2-4 times more runtime in them doing same work/performance. If you look at the environmental impact calculation a saw make, its a vast difference if if it runs 500 hrs or...

There was EPA regulations long before that the manufacturers had in consideration when building saws, just like now but not as stupid. They changed a lot over the years and make less sense everytime. Look on saws in 80's. Thats the reason we got different models and versions on export saws made...

There are set limits, parameters that can't be changed when tuning saws. Physics is one of them. If you put some work in the saw you can alter most mechanical stuff in it and affect pressures, flows and temps. 262 is a large branching saw, not so much torque as needed in a felling saw like 162...

Tuning a saw is not just about rpm per say its about performance. You can take 10 saws of same brand and model and they all perform differently if set after rpm's. I set them after best performance. Doing that allow you to find the ones that is a tad better o worse and know what to do do if...

Accracy was very bad. You could tell rpm was high or low, I was more precise in my ears then app was. Its no good to use if you wish to know in any accuracy under 5000rpm. I bet most can hear rpm better than these apps.

I used one of these apps in a chainsaw test. We then tested same saw in three phones and got very different results as microphones have different soundfrequence the take up just like ears. Mine less than most...
