i have older 1993 200 mercs, and one is a pain to get started.
The first start of the day is a real pain in the azz! After the first start up the rest of the day is easier. if i give it a little gas it will fire right up. If i just hit the key it will fire and die, till you give it some rpm’s and blow it out.
I have changed the pugs, wires, ball, and a sea foam treatment.
Once you get it running it runs perfect, doesn’t miss, and idles fine.
What do you think? carbs need rebuilt?
