An Italian Stallion: Alpina A-90

[blsnelling]

If it runs half as good as it sounds and looks, it should make a great GTG piece.

I'm looking for a filter that I can modify for this Alpina. I need a filter that measures at least 4 5/16" x 4 1/2". The bolt hole is 2 3/16" from the front edge.

A picture might help us out. Maybe with some measurements on it?

4 5/16" left to right
4 1/2" front to back
2 3/16" from front to bolt center

Looks a lot like the Remington 55,65,82 type filters.

How thick? I am guessing a cover goes on top and it looks like there is a grove around the perimeter of the "air box" that the oem filter fits in? Did the oem filet have rubber on the edges so when you tightened the cover down it made a good seal?

I made up a filter for a castor saw I had with a piece of Max Flo filter material, & used 1/2 x1/4 sticky one side neoprene on each side of the filter Worked fine for the 18 or so months up until I sold it on & as far as I know it`s still doing it`s job

What about a MC 250 filter. They are pretty wide. Or this setup McCulloch Vintage 200 250 Chainsaw Air Filter New | eBay

That maxflow material looks like it might be a good option then since it can be trimmed down.

Just got back from the barn.The Remingtons are 4" wide,4 3/16" long,with the mount bolt center low instead of center high close but no seegar.

ProMac 610/655 filters looks similar......?

Just throwin it out there

 

[Eccentric]

XL-700/800/900 Series Homelite (SXL-925, etc) looks similar too. I guess I should go out to the shop and measure one. Will do that tonight after work if I remember...

 

[blsnelling]

I appreciate the help guys. I'm betting that there's a Mac filter out there that would work.

neat old saw, and big too

 

[Icedogs28]

thought a filter off one of my old homelites would fit... just got home and measured it... close but no cigar. good luck brad!

hello! sorry for my English! . I have a chainsaw identical to yours Alpina A90, only unfortunately I have great problems with the carburetor, it remains set, adjust it make 1-2 cuts and disrupts. can you help me in that sense. where can I order a carburetor that fits this chainsaw. or maybe you have some used parts sources? Thank you!

 

[Little Al]

As this thread has been revived, Brad did you manage to source an air filter/ material for the A90 ?

 

[Woody912]

what size is the air box?, looks like a homey or lombard air filter could fit right in......................

It do look a whole lot like a Homelite would fit!
