GEM has all the gaskets for the engine except head gaskets.

You can find carb kits on FLEABay.

actually, the double pumper Mac carb kits are easier to come by, as Walbro and/or others still makes most of the diaphgrams and gaskets for the WDA-1 Walbro carbs. The WDA-1 kits have all the essential gaskets/diaphgrams, you just need to get duckbills (Elder Rubber). You'll see a bunch of familar carb parts here....

the WDA-1 gasket/diaphgram kits are only $11 .... http://www.mfgsupply.com/m/c/07-410-2.html?id=39EA4zvG

The 91 series carb fuel pump diaphgrams are harder to come by (same fuel pump diaphagrams used on the small flat back carbs also), I don't know a current source, maybe someone else does?
