Light chainsaw recommendation?

I will be interesting to see the Husky fuel injected saw, I cant get hold of the parts list to compare it the the 500i. The 500i is built completely different to standard non injected saws and it is more of a PITA to strip down. Ive rebuilt a couple of them and you need to strip them to bits just to replace the piston and cylinder.

Interesting. What's so different? The injector bolts on and off like a carb. Is there a separate air inlet? Any sensors on the exhaust side?

[Mark_Skyland]

Its built a lot differently. Where the carb would be is just a butterfly valve, the injector is below that directly into the crankcase. You cant just bin a carb and bolt on an injector. No sensors on the exhaust, there is one behind the flywheel. It doesn't monitor exhaust gases like a car would from what I can see.

 

There are a few YouTube vids on stripping a 500 down, I did mean to make one but we never have the time and my workshop isn't in the best shape to make decent video watching content to say the least!

 

I cant see there being many other fuel injected chainsaws as all the money is going into battery machines. Although maybe a big 120cc equivalent Husky, I only say that as they dont have one and its been what 4/5 years since the 3120 was axed. Im sure that they could have brought an autotune out in that time.

I forgot the injector didn’t have an airflow butterfly on it. That’s yes, quite critical for a bolt-off, bolt-on swap. 
 

Video of a 500i injector for anyone who’s never seen one btw. 

 

 

 

Now ask me why I have one on my windowsill…

I can almost be bothered to go and take the back off the saw to see how it works. Almost.

 

Tell you what. I'll finish what I'm working on now first and become a chainsaw manufacturer another time shall I.

Interesting, thanks.

Stihl have the MS300i, it is a fuel injected saw.

It was a false yt video, people will do anything for a click.

I actually watched the beginning of the video and when I noticed it was a 261

and a jackass just dreaming of what a MS300i should be like I realised he was a fake/ click bater.

I could not remove my post so no link in it to fool others.

I used one briefly and yes it zipped up almost like a ported saw but I thought it felt a bit flimsy for a bigish saw . Yours I take it is holding up ok ? 

 

They do feel a bit floppy, the answer is the 'Hard Stihl AV kit' (1138 007 1003), makes a big difference.
