Plastic float leaks, Tech Talk

First for me...in my nearly 20 years and countless thousands of carburetors with plastic floats to see one full of fuel

A Ruixing carb on a Briggs 16.5HP Intek. It is on a brand new DR Brush Cutter and will be covered under warranty.

No doubt this has got to be from a manufacturing flaw and not age, fuel, contaminants etc. Still I was pretty amazed when I noticed it.

This engine uses two carbs, the other is a Nikki. I dug through boxes of old carbs we have and found 20 or so of the Nikki, but not one Ruixing, and of course the floats are not interchangeable.


Just needs a bigger hammer
Peace

I've seen it only on Chinese carburetors that I can recall. The MTD powermore engines mostly. Ruixing carbs come from there AFAIK.

This junk is getting cheaper and cheaper by the day. I've been seeing chinese starters breaking a lot recently too... the entire case, the machined gears, etc...

Yep I have seen alot of the Powermore engines also with the full on plastic carb, and not only on MTD. To remove the jet/emulsion tube on one of these requires a new one be installed

I am not liking the Nikki versions though either, the brass jets are held into the plastic only by orings that will barely fit over a toothpick. Once the o-rings go, the fuel is no longer metered and the engine will flood out.

One good thing about the Ruixing is it seems to be a knock off of the Walbro/Briggs which is still much better than the Nikki Idea IMO.
