Lawnmower Carbs in Ultrasonic Cleaners?

[mikerecike]

Am guessing the metal carbs would be fine - any experience/wisdom re: US cleaning the briggs plastic tank top carbs in US cleaner?

 

cheers

Never had reason to us clean them as they are so easy to clean

i can not see any problem as long as you use the right chemical

You should be OK, it is only very thin metals you have to be careful with such as the escapment springs on clocks or thin foil.

 

Plastic probably won't clean up as well as metal but there is no good reason you can't use a US cleaner on plastic parts.

I,ve never needed to US them, a couple of blasts of air in the right places and it should be clean.

The biggest problem with the plastic carbs is distortion, so if I were to US clean them I would not put the heat on or let the vibes heat it up.

I always replace the diaphragm on service, but usually leave the old gasket in place rather than fit the new one, because it has moulded to the carb body and seals against air ingress a bit better.

If it runs rougher after refitting than it did before, take the carb off again and add a second gasket (the new one you did not use) between the diphragm and the old gasket. That normally cures it, if not fit a new carb, they are under £20. I keep a couple in stock all the time.
