U can easily make block off plates yourself for free. I had some 1/8 inch aluminum sheet metal in my garage and just made some paper templates then traced out and cut em out of the metal. Add some gasket maker and bolt em on. Pretty simple.

 

Not sure it was dark when I saw it and the throttle response was retared a lot, and slow to gain. Once I get rid of my 3rd gear fuel starvation I will start my carb stripping. But I guess my biggest question is what is the gain for the effort of stripping these carbs down, faster throttle responce, more HP most fuel consumption?

 

I will post in here the type I am thinking of doing it was published on rx7 club.
