Those are some good points BB. It seems that once the engine reaches operating temp it starts right up. To get it started when cold, I can shoot throttle body cleaner into the air cleaner on the OHG post or pull the air cleaner elbow and pour in a cap full of gas. Once it starts it runs great. Climbs ramps, idles great, etc. The low pressure vapor line seems to be fine. Earlier in we had ordered a new Nikki regulator, my tech had determined that that pressure was a little high- we ended up pulling it back off when it didn't help (and have since put it back on). When the old regulator was back on, I tapped into it and showed the pressure was slightly high (with a simple dial gauge) but stayed steady enough during the attempted crank cycle, so it seems the lock off is doing ok. I still may bypass it to eliminate the possibility of it being a problem that you had. Thanks for the suggestions!
