Yamaha ox66 issues

[striper56]

Here is the update on the still not running correctly motor. I installed 3 new LP pumps. The motor sounds better but still cutting out when increasing or decreasing the rpms from 3000 rpm down to 2000. I took a 6 gallon tank with me and connected it to the LP pump. Still didn't run correctly.
One time I shut the motor off and could not get it to start. It sounded like the kill switch was disconnected but was not. Tried a few more times still nada. Went back pumped the primer ball switched the battery to both and it fired right up and ran fine.
Great website VancouverPotter23. I will add it my favorites.

Thanks
