Berryman Chem-Dip

[i386]

Well, I let my motorcycle sit up too long with gas in it. It would only run with the choke on and not very well. I went to AutoZone and picked up a can of Berryman Chem-Dip. It comes it a 1 gallon paint can and has a strainer basket inside. I paid $20 for it but was thinking it used to cost a lot more than that.

I drained the gas, pulled the tank, and pulled the carbs (2 of them). Both slow jets were completely clogged. Both main jets were partially clogged. Both emulsion tubes had junk in them too. Both float bowls were varnished and had sediment in them. Both needle and seat valves were clear. I soaked all the aforementioned parts in the Chem-Dip for about 30 mins., rinsed them with water, and blew them dry with compressed air. The .004" slow jets required a second cleaning.

After that I put it all back together and topped it off with some fresh gas I bought earlier today. After the fuel lines were primed it fired right up with no choke required. Good throttle response, no more popping. Took her for a test ride and it ran like a new bike. It took about 2 hours to get it done. Great stuff, highly recommended. If you need to clean a carb, this is the stuff you want. Just remember to pick up some nitrile gloves and wear eye protection as it is some nasty stuff.

This Winter I will remember this day and winterize properly this time.

Interesting I just noticed it yesterday at the zone for $20, I also think it use to be alot more.
I dont have any running problems but was wondering if it cleans the outside metal housing at all like when a carb is new ? I think that pretty new carb look might be plating but am not sure ?

I used to use NAPA carb cleaner and once left a small screwdriver in the basket....... I got back the clean shaft and blade .....no more plastic!!

I think the cans of canned air are a great item to use when blowing out the tiny passages in small carbs too.

I can only speak for the carbs I've worked with, which is only a few on small engines. None of those appeared to be plated. They appear to be cast aluminum with some machining afterward. I feel pretty confident had I soaked the whole carbs they would have looked brand new on the outside.

The spray carb cleaners work decently to clean grease and dust from the outside. If you want to clean your whole carb with Chem-Dip you'll need to take it off the engine and remove all plastic and rubber parts first.

Re: Berryman Chem-Dip

Do NOT let the carbs soak for too long ( like if you forget them ).

All you will have left is mush.

Re: Berryman Chem-Dip

+1 for not soaking carbs.
99% of carbs are pot metal that are glazed over. If allowed to sit for to long, carb cleaner can and will eat the glaze up.

I soak carbs in hot sudsy water with some degreaser in it (cheap purple power). On bad ones I repeat the process, and on the last dip i'll just use hot water (to get all the soap out). Then i'll use carb clean spray + some compressed air in all the passages. After i'm done i'll flow test the carb by hand with the compressed air.

Make absolute sure you remove the plastic and rubber orings and such first!!!!!! That chem dip crap stinks bad too.

Re: Berryman Chem-Dip

Berryman Chem Dip does clean, but its not the best... our shop used it for a couple years, but it does more harm than good in most cases. Like stated previously, its a glaze eater.

A good, safe cleaner for carbs is Yamaha brand Carb Cleaner. Its sold in a quart bottle at most Yammi dealerships. Use it straight as a soak (Yamaha recommend cutting it with gas, but we found using it straight is much more effective) and you'll be surprised how clean it gets a carb. Also, it doesn't eat plastic or rubber! It even smells good.

Re: Berryman Chem-Dip

It's interesting, I was reading my shop manual for my 1988 johnson 90hp and it says in several places "Do Not soak the carb in carb cleaner"

I didn't know why but i do now.

I'll try the hot soapy water first.
