K&B .67 fuel delivery problem
Am having a problem getting a consistant fuel flow to my .67 outboard. It's still in the break-in period, so I'm running it rich, and at moderate but varying speeds. It seems to have the most trouble accelerating after decelerating for a turn. Pickup is located stbd aft in the tank, so air is (so far) not an issue.
I did notice one thing. There is an air gap of approx .018" between the exhaust adapter and gearcase surfaces. It does leak out exhaust, so this may cause a lack of exhaust pressure. Is this gap supposed to be there? Doesn't look like it should, but you know how it is when you're just starting out in RC.
Also, how much deflection is normal for the prop shaft? It's gotten a little loose, and I wanna keep it decently balanced. Yes, the brass prop was balanced well on a magnetic balancer.
I know these are really basic Q's, but you gotta start somewhere in this sport. :- Thanks in advance for replies!
