For carbs I use a heated dawn dish soap solution in an ultrasonic cleaner. Most cleaners should work better with heat. You might try it with pine-sol. The heat idea is not new but should be considered if you are using water based cleaner.

I don't use heat with combustible cleaners.

My first time using a non combustible, didn't think of heating it. I usually use Berrymans, wouldn't dream of heating it any. I do use hot water to rinse. I keep lookin at the ultrasonics at HF...
The pinesol actually made the shop smell good, unlike the other carb cleaners.

The HF unit has a parts tray which people don't seem to like.

Amazon sells what looks like an identical unit but with a basket. Kendal Industrial Grade 160 Watts 2.5 Liters Digital Heated Ultrasonic Cleaner for $5 more but then you can't use the HF & off codes.

I have abused the snot out of mine. The kendal may have a longer warranty.

That's a definite perk, glad others can use it. I always wanted to try it with an ultrasonic tank but haven't bought one yet.

Was just out using my 100 to move some brush piles. It's the first time it's been run more than a few minutes in the past 5-10 years. Every now and then the float valve (rubber tipped) either gets stuck or gets a piece of grit in it effectively holding it shut. This kills fuel supply and then the engine.

I was going to disassemble the carb and go with the traditional carb cleaner bath. But now I'm thinking I'll just pine sol the whole fuel system, tank and all. Anyone successfully use pine sol on a truly problematic carb?

The problem with that will be that all the crap in the tank will get loosened up and run through the carb, I'd clean all the components individually.

I bet your wife was impressed,,,with the toilet.

I read on a motorcycle forum a while back, they use lemon juice concentrate and hot water with good results. Might give that a try as well.
