Ready to kick this pos down the road…

The carbs were good and clean when they went on and were tested last year. The fuel killed them post winterization in January. Thankful though. I wouldn’t have found the main well plugs missing on the starboard secondaries. That could have been really bad.

Yep. That was on the one that wanted to run right, too. Go figure.
TomR had four of these on blower motors that he got in a new boat. Ended up replacing them with Holleys because he couldn’t get them running right so I bought a couple he had for sale. I think I found the issue…

Couple of things…
The carburetors were full of ethanol powder. Also, found that one of the meter blocks was missing the mail well plugs (really Barry Grant/Demon/Holley??).
We also found that the batteries were a little weak. That may have caused issues with the ignition even though it was charging at 13.5-13.9 volts at idle. The port/#1 battery was the worse of the two (with the port engine acting the weirdest).
The carburetor issue really was the biggest pain in the ass. They were a real mess.

What the Hell is "ethanol powder"...?
Thanks. Brad.

Here is some extreme examples from several boats this summer i worked on. Alot of other times, it is slighter amts, so looks like slight amt powder vs clumpy as shown below, lots of times just in the fuel bowls but get’s pulled into the metering blocks and etc. Basically, in places the fuel seems to evaporate from and leaves whatever additives don’t evaporate.










Eewwwe.....

Eewwwe.... is right.
That's a pretty extreme example but you get the idea. It was yellow and brown and sticky. Handling them, my hands felt sticky like from sugar/honey and was hard to wash off. It was an effort to get them cleaned out.
The smell though... I've smelled plenty of bad fuel before but not with an organic "rotting feet" odor. Nasty. Thankfully, this was not what was in the tank. We drained and filled and replaced filters just to be safe.

Yes, use non-ethanol fuel. Or drain ethanol and fill/run with non-ethanol before putting away. Thankfully, I have Rec 90 right around the corner now so this shouldn't be an issue. I'll also drain the carbs at the end of the season just to be safe.
