Walbro Meter Gauge

       Remove this ad - become a site supporter!
Does anyone know where I can get a Walbro fuel meter lever gauge.

I have tried everything I have been told and everyhing I have read to get my midrange and low midrange to stop burbleing and miss firing.
My high needle is 1-7/8 out and my low is 2-1/8 out. If I try to lean the low needle any further the engine dies from lack of fuel when i advance the throttle quickly or even moderately quickly.
I even tried richening the high needle as I lean the low needle. Transition still starves for fuel.

From everything I have read, it points to the needle valve lever not being set correctly.
So I want to pick up the Walbro gauge ( part # 500-13-1 ) and check the lever setting.

Anyone know where I can find one in and around the GTA ???

Re: Walbro Meter Gauge

It's a natural characteristic for them to gurgle and stutter in midrange. It's because they're unloaded. If they had an accelerator pump on them like a car motor, they also wouldn't do it. I have a very old carb off a 1950s McColough chainsaw on a modified 60cc Homelite saw motor that had an accelerator pump on it and it is the only one I've ever had that ran smooth through the whole speed range.
Tried for my kamikazi pilots licence. Flunked the test.
