As being a mechanic, this one has got me thinking.
My 23 Caribbean is fitted with a 5.7 ltr 250 hp Mercrusier,1997 fitted with Mercarb.
Starts easy and the choke stays on for about 15 secs and goes off, running at 1000 rpm.;)
Bring it back to idle and then it starts to to run rich, so I increase...
