Re: Carb crud

This morning I tried dissolving the stuff in E-85 (ethanol), E-10 (normal gas) and acetone. So far It doesn’t entirely dissolve in any of those. Given that the filter had been bypassed I’m wondering it some of it is just dirt (sand). The liquids turn yellow so clearly some is going into solution.

On soaking in carb cleaner, somewhere recently I read a service bulletin (or something) saying not to do that as it would remove an anti-porosity coating from the carb castings. The advice basically was just carb cleaner spray and compressed air.

What say you experts on this?
