I see that Oldschoolshovel has resurrected this old thread, so will take the opportunity to update some answers:
(1) Oldschoolshovel - PM's require the poster to have a certain number of posts; but my website is listed in my signature block.
(2) Winter storage and diaphragms: I have found NO solution to this other than starting the engine on a weekly basis. I personally purchased a small engine where the manufactured required Stabil or the warranty would be invalid. Did the Stabil per directions, and next spring carburetor was completely clogged, and a clogged carburetor was not covered under warranty! Did some other small engines, all had the same result. Will not try this expensive mistake again. Those who start their vehicle weekly, allow the engine to warm, and move the vehicle twice the diameter of one tire, will have significantly fewer repairs the next spring!
(3) Not covered in the thread, but some issues some folks are having are the result of trying to use an incorrect flange (mounting) gasket. The Carter carburetors DO NOT LIKE THE ROCHESTER MOUNTING GASKET, USE THE ONE SPECIFIED BY CARTER! Ports in the Carter do not align with the holes/slots in the Rochester gasket. No, I do not know why; and I have outlived my friends (now missed!) that were engineers at Carter, so cannot ask them. Any "rebuilt" carburetor "should" come with the correct mounting gasket. If one orders a kit, and rebuilds the carb oneself, then the rebuilding kit should have the correct mounting gasket. One may use the spacer if one wishes, but the Carter specified mounting gasket should always be placed directly under the carburetor.
(4) Swapping parts (i.e. throttle bodies to change mounting spacing) from one carb to another is a bad idea, regardless of the brand of carburetor, unless both carburetors have exactly the same identification number!
