I have a 1983 Bayliner Capri with the AQ125/270 unit. I have gotten everything running after sitting for 2 years with no work being done with it. I have replaced the fuel pump with a low flow electric one. Is this the correct type or do I need a high pressure one? After taking the carb apart and fixing a minor problem with the floater unit on the carb it runs fantastic in the drive way.
I took it out to the lake today and ran into a major problem. While running at about 3000 rpm or above the engine will start bobbing(the best thing I can describe it as) the rpms as if its trying to stall out for about 30 seconds or so then it will work fine for about 5 minutes or so and then it will start doing the same thing again. There is no pinging and while not under load I get crank it to the top end with no issues. I'm really not sure what is going on and would love some advice and maybe I'm doing something stupid that I shouldn't be.
