help with merc carbs

[dicnasty]

i have a 2.4 200 with port work, 140 cylinder psi what carbs are the best for the set up and how do you tell the difference between merc carbs!

The stock ones work well.I have never had much improvement over merc carbs.You will need a merc manual to determine if what you have are the oem carbs.They will be listed in chart form in the carb section.The 2.4 came with probably 80 jet in cyl # 1,3,4 and 6 and 82 jets in 2 and 5 cyl.Maybe one jet larger in all which will be two sizes to start. hf...
