Hi everyone. Glad to be here!

This is my issue. I have a 2000 bf50a. Just had the carbs rebuilt, fuel pump and fuel filter. Done at a dealership. Ran great first weekend. All changed now. Still starts great and idle great. However I can not throttle up. Almost like it's missing a cylinder under load. I can increaae the idle easily when in neutral not under load. What I have tried so far.
New plugs (ones I took out looked perfect) another new fuel filter, new gas line and primer and a different tank of fresh fuel. Still exactly the same. I've pulled the plug caps at idle and can hear each cylinder drop off when I do.

Could the fuel pump be faulty? I'm totally at a loss right now. Bad part is where I had it done is 3 hours from where the boat is kept.

Any Help would be great!!

 

If you squeeze the bulb will it power up?

 

No does not change it at all.

 

I'd take it back.

 

I would have already, problem being is its 3 hours away from where the boat currently is and that would be with it being on the pontoon and the wind the the pontoon takes and expensive drive as well!!!

Anyone else?

 

Well, I know some will react to the bulb squeezing. If it gets more power then there is a vacuum leak and it usually means tearing it down and sealing everything.
