Parallel. I turn it perpendicular when I manually inject fuel from the bulb. The dealer’s mechanic told me to that. That’s only 29 years ago. I always wondered where he ended up. Rusty? Red? Something like that. Sandy Creek Marina, Breckenridge, Texas. Yup, I’m getting old!!Maybe the primer solenoid is stuck open? Is the red lever parallel or perpendicular. to the block.
