Okay I know this might start a debate but here we go.

My 20hp 1984 motor starts great every time. If it sits for a week or two, prime, choke 4-5 pulls and its running. If I use it daily or even every other day 1-2 pulls it starts. But once it starts I have to keep the choke at 1/2 or it will stall at idle. Once I'm moving it can handle full throttle without choke and it runs smooth.

Is there a quick solution?

I guy down the lake recomended seafoam and deepcreep. I put some in the premix tank when I filled it up. I mix 50:1. Will this really clean my carbs and is that my problem?

Thanks in advance.
