Jonsered 590

Here is my start to a 590 project.

 Just so you can see what a 590 looks like inside.  I really like the set up on it.

Thanks (also for telling me about this site)!

Did you measure the bore of it?

This site looks really promising!   ;D

45mm fits with the info I have from before - but I believe it is 50.9cc, maybe 50.8 (seen both numbers), but not 50.7.

The exact cc is an "academic" question, I just wanted to get confirmation that it wasn't the same 46mm/53.2cc as the P5500.  ;D

Poulan 325 is 46mm and I got one.  The top end fits on the 490 590 5000 500 50 special to if one so desired a cheater saw.

Me either anymore and post wasnt about racing, but the term I used was. Sorry about that confusion.
But what I was referring to, is you could bolt a PP 325 top 53cc on the 490 5000 500 50 special and gain a great deal of torque in the cut for a firewood saw with the same weight of the 49cc saw.

I guess so, or a P5500 one!

Was out in the barn today and took some pics of a 5000+ 490 top end compared to the 590 top end.

Crappy cell phone pics.
