Is your 505 using fine mesh for filter?  My 415 and 505 is.

The 475 is indeed an odd setup. 

I found 2 new poulan tanks with the different filter set up of 475. I am going to compare and see if I can run the 505 filter set up on them.

If memory serves, at least the P7700 were made in both configurations, at different times.

I did a google images search and found a partner 7700 and partner 660.  I think they are Belgians saws if I remember right. Couldnt find any pics under the carb covers though.

Partner and PP had the smaller ones (65 and 71cc), but not Jonsered. 

What was the model number of a 71cc one? I know of 65cc 77cc 82cc but I've must have missed this 71cc one.

The complete series of Poulan Pros based on these are the 415, 425, 445, 475 and 505.

The 445 would be the 71cc version.

My 505 is identical, fine mesh filter with blue air duct coming off the flywheel. Though I haven't run this saw or its kin to know, I seems like it was a good idea. Wonder how much air pressure is built and if its worth trying to gain more?

The Husqvarna 365 special and 372XP have air injection

The air injection on this Husqvarna can give confusing impressions?

To remove the air injection and the adjusting needle baffle and do nothing else - - the engine will run noticeably faster

But this faster running is because the engine is now running leaner. To re-adjust the needles to the same mixture ratio as before - there is little difference.

This difference in mixture level is caused by the ambient pressure level inside the air box and its effect on the metering valve diaphragm vent hole of the carburetor.
