#3 SH .37 Bench Runs with simple venturi conversion

This video illustrates the results of an inexpensive CL conversion of the SH37. It requires only a custom 'true venturi' and parts from the supplied throttle (main jet NVA and the securing bar). The venturi diameter is identical to the ST style (.161") in the first runs. This bench run was performed with only the custom tube muffler. The run appears quite similar to the run with the first venturi setup.
