Help!
I have an older 40hp two stroke Mariner on my 13ft Whaler. It starts up fine, gets up on plane and will run great top end. As soon as I bring it back down to trolling speed or idle it bogs down and sometimes stall. If I power up again it will bog down then sometimes fire back up to life. Runs great then runs sh#tty.
New gas (treated), new gas lines, new filter and separator, good plugs.
Was thinking of doing the Seafoam decarb? Or PB Blast the cylinders?
Any thoughts, suggestions or advise will be greatly appreciated.
