I have a 86 Johnson 175 on the back of a Stratos 189sf, I have just rebuilt the carburetors, put new plugs and wires on, as well as a new fuel line. She seems to idle decently but has a miss in mid to high throttle. It has even compression across all 6. I was thinking of starting with the coil packs or the fuel pump. Does anybody have any experience with this year of motor and have any advice? Thanks in advance.
 
I am going to be blunt here.------A common theme --" carburetors are rebuilt but still does not run right "--------So post your compression numbers of a test done today or tomorrow .-----Perhaps run with a timing light one cylinder at a time to see if you can pinpoint the problem cylinder !------Or look into each carburetor bore at full throttle to see / compare fuel coming up each carburetor nozzle.----Test run with the cowling off the motor.------Trouble shooting beats crank and hope parts replacement every time.
