Bulk Carb Cleaner

[mscher]

I've been advised to give the 72" Merc carb, the old dunkeroo, for a thorough clean, but the only carb cleaner around here that is not a spray, is almost $30, for less than a gallon.

Any alternatives?

I have a gallon size can of Berryman's Chem-Dip. It has 96 oz. of cleaner and not 128 oz. because the can would overflow when dunking parts in the basket. The can is 5 years old and has has been used many times and is still good.

A spray can is used until it's empty and you buy another can, I have no idea how many spray cans I would have used by now, but I do know dunking is more effective than spraying.

My dunking can has cost me $6 a year so far and cost per year is dropping. In another year, $5 and a year later, it's down to $4,25.

What I'm saying is don't be put off by the 30 bucks a can. Also Walmart carries Berryman's for less than $19 and if the local store doesn't have it in stock, free delivery to the store only takes about 3 days in my area.

How long does one usually let the carb soak?

I soak overnight. Probably over doing it, but the carbs are stripped so only metal parts are dipped. The stuff is not good for rubber and plastic.

Some folks use and recommend an ultrasonic bath with a variety of solvents for carb parts....I think Harbor Freight carries some ultrasonic cleaners.....

Buy a gallon of BRP Engine Tuner. Best carb cleaner you'll find.
