Still trying to get my grandpa's old boat to work. I just spent $600 at the local Johnson/Evinrude shop - they replaced a bad coil, adjusted the timing, fixed a bad ignition switch, replaced some plug wires and got it running great...at the shop. Unfortunately, when I took it out in the open water it still didn't run the way it should.
The motor is a 1983 Johnson 60hp. It starts up very easy, idles beautifully and shifts like a champ. The problem is that it bogs down considerably at medium to high speeds. If I throw the shifter all the way forward I get great power for a split second, but then it bogs right down again.
I have already done a carburetor rebuild, so either it's not in the carbs or I didn't do the rebuild right. I know I put everything back together right and I know I got the float measurements correct. I had a Johnson manual and followed it to a tee...with the exception of two things. 1) I did not blow everything out with a high pressure hose; and 2) I used a makeshift screwdriver to take out the low and high speed orifices - their were some very small burrs on the high speed orifice.
Did I screw up the rebuild or could there be another solution?
Any help would be greatly appreciated.
