KB 3.5cc gold help
Hey guys Iam having a lot of trouble with one of my kb 3.5cc gold ss engines. I know that the hs needle on the stock gold carb should be 2.5-4.5 turns out but my boat keeps acting really lean and I am around 6 turns out and it is still acting lean. I started at 3.5 and continually richened up but it does not seem to be changing. Also the idle is really higheven though the carb is maybe1/16 to 3/32 open.Also,I tried to kill it by covering up the carb with my finger and it would not die.Dont know ifall theinfo is relevant, just thought idprovide as much info as possible.Does anyone have any ideas on what to do?
Current Setup
Engine-Stock
Plug- Os A5
Prop-Prather 215 or 220
Fuel-SIG 55/19 boat
