[QUOTE="Pappy, post: 273999, member: 3278"] Unless your boat/load is very heavy I would think your numbers are low. For your idle issue try adjusting your low speed needle. Since you mentioned it was shaky I would start leaning it until it smoots out and tweak it as needed from that point. On the high speed issue - that is right around the time that OMC started producing carbs with a fixed high speed jet in place of an adjustable needle. If you still have the needle then do the same thing and adjust to the highest RPM obtainable then back the needle back out around 1/8 turn for safety. If you have the fixed high speed jet there is always a chance that it is the wrong jet, is missing altogether, or some shade tree that thinks drilling out a jet will produce more power in a two stroke...... did that to the jet. Unless you have set of number drills there will be no way to tell except by replacing the jet and trying it. At any rate that would be a good time to purchase an OEM kit for the carb, thoroughly clean it and install the new kit. [/QUOTE]
