Hello everyone. I haven't posted much on here but I've been following and reading for quite a while.
I have a 200 3.1 ox66 that I'm having some issues with. I just rebuilt it and after getting everything back together the motor runs fine until it warms up then quits and wont restart until given some time to sit. After it dies it will try to restart for a few tries then just spin over. I have 35psi on the fuel pump and I've checked my ignition system and it's all good. I also checked compression just to be sure and it's good. I've been running to boat on an aux tank during the break in and noticed the first time it happened that the tank wasn't venting and was sucked shut. I opened the vent and even swapped back to my onboard tank and still nothing. I'm just looking for any suggestions for things to check out I'm stuck.
