"motor is a 1968 33hp Johnson.
"motor is a 1968 33hp Johnson. Trouble starter last year and I thought I had it fixed until today. There is a low speed needle and a High speed needle. The motor will crank and idle but will only run about half throttle when I try and open it up, if I adjust the high speed needle it will open up and run like a champ. When I idle back down it runs very rough or not at all until I re-adjust the high speed needle again and then it will idle, but then Im back to it not running correct at high speeds unless I adjust the high speed needle again. I installed a carb kit a couple of months ago but am just now getting it on the water. I have rebuilt this carb 3 or 4 times in the past 25 years with no trouble. This has me stumped as its very basic, the needle screws into an opening and you adjust it back out and go. I have done it a 100 times but never had this happen. Im wondering if the carb is just worn out. I have a spare motor that was low hours and Im thinking of yanking the carb off, rebuilding it and installing it on my motor unless someone can offer up a better suggestion. Thanks for any advice.
