Test run.

Here's the test run of a 5hp camshaft stuffed into a 3.5hp engine. Runs very smooth and lots of power. The engine limits the power output with a governor but as you can see I over ride it briefly to show the potential of the power output of this cam if you install the proper governor spring (the green one). The cam could also benefit from 0.020" to 0.030" ignition advance for some serious RPM's and power levels.
