What's ya'll Opinion of "Berryman B-12 CHEMTOOL"?

[7394]

Yelp, I've found that if an engine is running rough because of a partially blocked carb, a little of this stuff
mixed in with the gas running a while, the engine in a lot of cases will level right out and run smooth. If the engine won't even crank, then the thing to do is clean the carb by hand. INMO it's just another tool in the
box. Guess that why they call it Chemtool

Won't even crank, battery would be my 1st check..

My oil is better than StarTech's oil.

Chemtool is one of a few products that work as described .

Approx 1975 a fellow had a ford 240 ? engine that had been driven at grandpa's speed and seldom reached operating temperature .
If not for chemtool I'd probably still be trying to get the lifters out . It dissolves varnish too .
