    It is VERY dusty where I live. We've had about one inch of rain since August. I've been wanting to upgrade the air filter on my 2000 Scag Tiger Cub since I bought it last fall.

    I was lucky enough to find the filter unit on Ebay for a reasonable price, but I learned that the carburetor air horn is quite different on the old engines vs the new ones. There is no adaptor for the old ones, so I made my own.

    I'm not a machinist, so I used what was available: a 3" x 3" x 7" block of aluminum billet, a drill press, a compound vise, and a couple of end mills. After I got the basic shape down, I was concerned about the weight. I didn't want a 5 pound weight hanging off of the carburetor. I finally whittled it down to about 1/2 pound. Since I always use a grass catcher, I made a bracket for the filter unit and mounted it securely there. I used a 2" radiator hose to connect the adaptor to the filter. I added a filter minder, too.

    Photos are attached. I still need to get some larger hose clamps, but these work fine.

    So you are using one filter,there is no factory filter.

    That looks pretty darn good there steve!

    Off topic- I think it'd be a pretty good setup to have a dual filter. Have that donaldson on top then close off the intake ports of the stock location and have the stock filter as a secondary. I imagine it would take some kinda work though.

    I'm just running the large canister with the dual element filter setup. I don't know if putting the factory filter in series would accomplish much more. Might be too restrictive.
