Really CLEANING a carb.

Recommended Posts

slantram

I've read of many ways to clean a carb. Here's what I do and it works very well 99.9% of the time. Disassemble completely-place in an empty coffee can-pour in enough Strypeeze Paint and VARNISH remover to cover the carb and let it soak for a couple of hours or overnight. Remove and rinse with HOT water then spray with carb cleaner in all the small orifices and blow off with compressed air. Even if this is one of those carbs that is green and stinks to high heaven it will come out looking BRAND NEW.   slantram

Looking a the MSDS it looks like that solvent would work well, as long as it is not the gel........

 

I use an acetone, Methyle Ethyle Keytone, & laquer thinner overnight in an ultrasonic vibrator (the cheap ones from harbor freight), then rinse in krud kutter & hot water.  Then switch over to a hydocloric acid and warm water until it starts to slightly darken the aluminum.  The reason for this is I want all orgainic stuff tucked inside all the passages to be eaten alive.  You need an acid to do this.

Some paint and varnish removers contain bases that quickly attack and dissolve aluminum. (OUTSIDE.....put aluminum in a plastic container of Drano or caustic solution and stand back). Don't breath the fumes either!

Any Ammonium Hydroxide, Potassium Hydroxide or drain cleaner, (sodium hydroxide), will destroy an aluminum carburetor along with any base pH solutions that I see in varnish removers.

Your Strypeeze Paint & Varnish remover doesn't contain any bases BUT it does contain 25% to 30% dichloromethane. Dichloromethane will react with aluminum at pure strengths and less so diluted but it will attack it to some point. The other solvents in it include toluene, acetone and some methyl alcohol which are fine.

 

I don't know about the acid dip long enough to change color either. Even a weak muratic acid will pit the hell out of aluminum.  :eusa-think:

 

Point is to be careful with what you clean these old carbs with. My NAPA one gallon paint can of carb cleaner works well for me and it states it is for all metals.

I've heard some folks use full strength lemon juice and have good results.

I use a can of Berryman Chem Dip. Its specifically made for carburetors and even comes with a tray to put it all in and dunk it. It doesnt hurt anything and Ive never had a carb it couldnt clean to brand new. Why would you use something that wasn't meant to clean correctly for what you have? Thats like saying its good to use 60 grit sandpaper to clean bugs off your cars paint or windshield....sure it works but its not the proper method

I use the heads off of my still as carb cleaner, (spirit distillation). Works very well.

Just called the ATF to try and confirm the Milford CT carb cleaning methods! :ychain:

That's a good idea!

I use rattle snake urine when I have it.  Works great.  I use carburetor cleaner from Advance Auto when I run out of the good stuff.

      Morning -  Looking for a carb.  There are plenty of carbs on the 'net, but 99% do not fit because of the choke configuration.
       
      Background info:  Engine - K321S, 14 Horse Kohler.
      Choke control cable is routed to come from BELOW the carb.  To close the choke, pull on the choke knob, the choke shaft rotates counter clockwise, and the finger tab sits at the 10 o'clock position.
      To open the choke, push on the choke knob, the choke shaft rotates clockwise, and the tab sits at the 1 o'clock position.
       
      Where can I get his carb?  Thanks in advance.

      When I purchased my WH (67 T877) it had the incorrect oil bath filter on it (it bent the front of the grill out) I took it off and placed a regular filter using just the oil bath cover. My question is...is it ok to run these Kohlers without the oil bath filters? I know they are better filters, but Im curious if the modern filters are sufficient.

      Hi Guys,
      I’m cleaning the Onan P220 carb on my 520H. It’s a Nikki 146-0479 carb. I was wondering if the main jet needs An o ring and if so which type and size? There was no o ring when I took it apart. 
      Thanks!

      Hello, I have a D 200. It has been running great, I was having a hard time starting it and I replace the filter and fuel pump. Adjusted the carb, and now under heavy load she will bog down and stall. If you are just driving seams fine, but if you tow a trailer with the mower, I boggs and stalls? Carb Issue or Fuel Pump?
       
      Thoughts?
       Thank you

      Looking for the correct carburetor number for a Tecumseh H60-75063B on my 654. This is the correct engine & model number, but I can't determine the carb number so I can buy an aftermarket carb.
      Thank you!
