changed carbs but more problems

I'm with everything Losthope just said. If you have swap meets in your area that might net the cheapest solution. The few meets I go to seems to have an endless supply of these things laying all over the ground, many in the $10 range. From a practical standpoint I think it would be somewhat involved and difficult to fab up all the pieces you might need, unless you have machine shop facilities at your disposal.
