China 390 carb main jet check blown

[davidwyby]

Filter failed, got full of dry oak debris. Sprayed it out with carb cleaner, still didn’t run right, pulled the Welch, sprayed more and noticed the rubber disc protruding into the bore. Punched it out…fixable ? Or replace?

Thanks

I’ve replaced the whole nozzle with one from a different carb that was the same physical size. Never replaced just the check valve

The rubber disc can be reinstalled or replaced. However I would second Kevin and replace the nozzle. They are available just need to get the correct OD.
