I've narrowed it all down to the pump. After a cleaning, performance
was much better. It was bogging at WOT, but recovering and staying
with a little help from the choke or bulb.
So if anyone could advise... Will a rebuild kit solve the weak pump
problem? The rubber diaphram seemed flimsy and stretched a bit, but
I've never seen a new one either. Otherwise, if I need to get a new
pump all together, will any VRO work? I've read that the newer ones
are better, so if they work I'll go for one.
This engine has the oil input capped and clamped and I mix 50/1. I'll
keep it that way for better reliability. Also, since I won't be using
the oil side of this pump is there another Johnson pump altogther that
can take the place of this VRO? Any links or part numbers would be
very helpful! Thanks again-
