Made up the parts for the exhaust valve. They are almost identical to the parts for the intake valve except the carburetor is replaced with an exhaust pipe. the spring on the exhaust valve is much stiffer also.
From the beginning I was planning on using timing gears for the cam shaft well that isn't going to happen. The distance from the crankshaft center to the cam center would require at least three gears be mounted in a row and they would be of considerable size. It would deter from the looks and be very noisy. I have decided to use a timing belt setup so I went looking for parts in my unused horde. I found a 15 tooth and a 30 tooth pulley and the shortest belt I had at 55 teeth.
The pulley bores were the wrong size so I enlarged the holes and pressed in brass bushings with set screws.
I made a crude drawing which showed where I would like the camshaft to be in relation to the crankshaft and measured the center to center distance. I plugged this information into a belt length calculator and it came up with a belt of 56 teeth.
I should buy a lottery ticket today.
I'm sure I can make my 55 tooth belt work just fine.
Thanks for looking
