I have a poulan pl3816 and want a bigger bar

[sasuke]

I have a 16 inch bar on a polan 3816 that was given to me I want to upgrade to a 18or even a 20 inch but am worried that it might not work and I don’t have the extra money to switch back to a 16 if it don’t work my bar now is kinda messed up from a bad pinch in a snagged tree

I'm curious , if you look at the epa sticker on your saw , does it have 42cc displacement ?
Did the bad pinch mess up the sprocket , guide rails , twist the bar , bend the bar ?
A relative has a poulan pl3816 and I remember it having a Oregon A041 mount bar .

You can always go to Oregon’s website & look it up. 18” is the longest, three different bars listed.

18" 3/8LP would be all that saw wants.

Many years ago I did have a 20" 3/8LP bar I used for testing on bigger cc saws for kicks. But I dont think you will find them anymore.

20 inch bar is too much for your 3816.

I've got couple 3816's and some equivalents and 18 is enough.
The engine really has to be turned good for a full bar cut using a 18 and a sharp chain.

The engine is more user friendly with a very sharp 16inch bar. The engine can be tuned little more rich for the 4 stroking. (engine does not have to be as strong)
