Initial problem was with not starting, but got that corrected with a new vaporizor-regulator. Then still had the problem so I bypassed the fuel lock(vacuum) and managed to get the lift running. The fuel lock seems to be working but not getting enough vacuum from the carb.

I think if I can get the carb tuned up it will give the fuel lock the vacuum it needs and also fix my hard start/rough running issues.

Any advice on getting the mixture screw set? And what should the idle be set at?

Thanks.
