Hi Guys,
I have a problem with my boat at high throttle. It starts good, and idles good, but on the lake it bogs down and won't plane out. I have gone through the carbs twice and every passage is clean. But I suspect I still have a fuel problem, so I want to run a few questions by the experts before I go back in to them one more time.
I rebuilt these carbs last year and put kits in them, but with these carbs, everything is fixed jets, no adjustments. So essentially all I did was thoroughly clean, replace some gaskets and the needle and seat, and adjust the float. I adjusted the float according to the factory manual, (parallel to housing), however I read today in a thread by Joe Reeves that the float needs to be angled just slightly upward when held upside down and not exactly parallel with the housing.
I feel like I'm flooding out, and here is why. When I pumped the fuel bulb after re-assembling everything, I notice a little fuel leaking out the front of the carbs, and the bulb never got rock hard. Also, when I took it to the lake yesterday, it seemed a little hard to start like it was flooded, and then once I got it running it idled good, but once again, it wouldn't plane out after idling past the no wake buoys. I also pumped the priming bulb, and it didn't help one bit. I thought it might be a timing issue, so I made some minor adjustments both ways on the timing stop, but it didn't make any difference. (I need to check timing to make sure everything is good once I can get it to run good.) I parked it and went out with the friends for several hours. On returning to trailer it, I started it up and kind of got on it a little, (no one around in the no wake zone) and it seemed to perk up and it actually got on plane, but I had to slow down after a minute and then it wouldn't pick back up after that.
To me this sounds like it?s flooding out or loading up. I think my spark is fine, because the battery CD ignition is brand new, I checked and re-booted all wires, and cleaned all exposed brass on the rotor and distributor.
So finally here is my question. Could it be anything other than the floats/needles not sealing good that would cause a flooding condition? Since everything is fixed on these carbs, is there anything else that can be adjusted to fix a rich mixture, other than the float/needle. I've essentially replaced everything on this motor. I am at the end of my rope and don't know what else to try except take it to the local mechanic, but I want to exhaust every possibility before that.
My thought is to remove the bowls, and adjust the floats a little bit to put more pressure on the needles and try one more time. If that doesn't fix it, it?s beyond me.
Any advice/ideas are very welcome. Thank you.
