The mixer is a CA100, the vaporizer I can't remember off the top of my head but it was the direct replacement. It does act like it runs out of fuel but if I hit the button on the vaporizer at any point before it dies it dies instantly. That leads me to believe that it's not a lack of fuel issue. I can't find any timing marks to use a timing light with. I have set the timing to the point of best results. As far as the compression it's between 116-125 across all cylinders. I've read several instances where the filter or the fuel lock out could be partially plugged or shutting down. I haven't found an external filter or inline for that matter. I am going to bypass the fuel lockout to make sure that's not an issue.
