Re: 1967 Johnson 80hp backfires when I mist fuel into carb
Update:
Took the boat on the river today and ran 12 gallons of fuel and 2 cans of Seafoam thru the motor. Motor ran pretty darn well. Drop tested all 4 cylinders and they all passed.
Motor still doesn't seem to be reaching max RPM. I can't be sure though cause I don't have a tach installed....yet. My son and I got her up to 32mph today. A month ago, I maxed at 33 with just me aboard
I can't find any numbers on my current prop, so I'm not sure if it's the stock prop or not. Gonna throw on the spare prop tomorrow (10 1/4 X 10) to see if it makes any diff. It might be the same as my current prop, but it couldn't hurt to give it a try.
If I'm at WOT, I mist my carbs with premix and RPMs do go any higher(and/or it bogs), does that mean it prob getting max amount of fuel it's supposed to?
I did the link and sync per the manual, but there's always the chance I've screwed something up. I just want to make sure that I know the fuel/ignition thing is correct before I start looking at the prop.
