Walbro WT Needle seized in!

[mikerecike]

Never seen this before. No fuel getting through - opened up and needle stuck fast - head came off as I tried to pick it out. Have I got anything to lose poking through from other side? WT 99 52.From Jonsered gr50 strimmer. Thanks folks

You may damage the seat and the carb will leak, i would leave it soaking in carb cleaner.

I would give it a go at a poke Mike. The needle has had it anyway cause the heads off. Pushing it from the other side should not damage the seat of the inlet drilling, and I bet it will not take much to shift it anyway. But as ADW says, a good soak first may help, or better still boil it up in the US, the heat may shift it.

Another thing you could try after soaking in WD-40 or carb cleaner is to assemble the carb on the pump side...take off the needle arm and connect a pressure pump to the fuel line nipple. You are doing what you would do to test the pop off pressure of the needle and it may move the needle out with about the same pressure you would use in the test. 20-25 psi is safe pressure to try i think.

Not too sure what that may do to the pump diaphram?

Pop the gauze filter out, put a bit of fuel pipe around the end of your airline, wind the compressor up and blast the little fecker out:thumbup:

 

Something has to give!

I figure the pressure/vac pump is controllable as you can ramp up to where you want to stop plus i would be putting a fresh carb kit in there anyhow.

Thanks all - much appreciated - was quoted £45 for a new carb so am gonna give this poking / blowing a go.

Or you could drill a small hole in the defunct needle then screw in a small self tapping screw which can then be pulled with pliers without damaging surrounding areas.

You may find that simply drilling the needle is enough to free it [emoji106]
