These are black plastic bowls. i have been soaking the jets in a carb cleaner i got from o reillys in a one gallon can. While i have them apart, what is the float drop measurement?

Below is a clean jet next to a dirty one.

So whats the best way to clean plastic carb bowls? :head:

You can soak them in SEAFOAM for about 20 minutes and see how much comes off. DO NOT use carb dip as it will eat the plastic. I personally use EVINRUDE engine tuner in the ultrasonic dip tank.

i've always used a 50 / 50 mix of mineral spirits and lacquer thinner. i use that on the whole carb assembly including the plastic parts too. then blow it all clean with the air compressor.

WD-40 seems to work good on plastic too.

There is a marine program at George Stone where i am taking welding. I am going to let them do carb kits on all the carbs and clean the bowls so hopefully there will be no more issues. After they do carb kits, they will put my outboard on the dyno and see what it puts out.

Update
 

Found out i had low voltage on two plug wires, had carbs cleaned, a few electrical gremlins with the ignition, and the shaft mounts and steering shaft are shot. Motor had 92-94psi compression on all but one cylinder which had 82. If nothing else breaks when trying to repair it, it would cost over $1000 just for parts.

So i am having another motor installed this coming week, a 1986 Yamaha 150 25" shaft. I will build a jack plate, out of some 4x4 1/4" wall square steel tubing i have, so it will work on my 20" transom. Now i just need a remote control.

Jason I strongly suggest that you source some aluminum angle for your jackplate..... rust streaks are a real pain in debut.

X2 And if you go near salt water at all metal rusts SOOOO fast...:head:
