I picked up a 65 hp moter and combined my lower unit with the motor i picked up. I had it out for 3 hours and it rand great but lost power in the last hour. I had a bulb poroblem that turned out being a brand new defective fitting on the tank end. I took the carbs apart and they looked real clean but the floats looked old and the needleds didn't have the clip that the new ones have. So I put my new floats and bowls in the carbs. The boat started at the dock and ran well. Then I had a hard starting problems. I noticed the floats I took out were adjusted slightly lower than even and the ones I put in were even. The motor has plenty of power when it does start but starting is tough. My question is can I simply adjust the low speed needles they are out about 3/4 turn or do need to put the other floats or adjust the new floats down a little. Do the low speed jets have any bearing on hard starting flooding issues? Turns out my throttle cable got loose on the shifter and this whole new problem I created. Not sure about float level and low speed adjustments. Sorry guys i tried to search before posting but my query for 65 hp carburetor came up blank. Thanks for the help.

Thanks. How did you find those? I typed search carburetors 65 hp evinrude and got nothing. I( took the carbs apart today and set the floats a little lower in the front the way they were before I put the new ones in. I was wondering if I could set those screws in my driveway with muffs or if reeves means in a test tank or under load. Seems like he comes out 1 1/2 turn and then goes in 1/8 at a time till the motor almost dies out and eases back about 1/4 for optimal range. I hope the float adjustment was causing my plugs to foul up. I'll take it out next week and see. Thank you

Hi, <br /><br />I just kept entering dif. search terms till I found what I looking for, couldn't find anything for you motor but I figured those wer pretty close.<br /><br />It doesn't have to be done under load, so muffs or tank's probably good, doesn't really have to be out of neutral.<br /><br />Glad I could help,<br />Mike :p
