It makes an even bigger difference if you use stainless steel fasteners to attach the block/carb and even the intake.

You had the right idea about using a spacer between the carb and intake. We ended up having to add one to my son's Matador. If you drove it and then it sat for an hour or two it was very hard to start. We decided that the carb was picking up too much heat from the engine. The spacer seemed to make a big difference. Todd
