Fuel Airlock????

Post by Bern » Tue Apr 05, 2011 2:28 pm

I have had a couple of incidents where I lose power. If I pull over I can notice that the fuel line to the rear cylinder is dry. If I simply tap the line the fuel starts to flow again. Is this probably just a sticky float? Or is there something else I should look at. Any suggestions would be welcome before I rebuild the carbs.

Hi Bern,
If you had a sticky float the fuel line would still have fuel in it and not be dry as you indicated. You just wouldn't get fuel into the carb float bowl.
If the line is dry as you say it probably is the fuel petcock. When you tap it it jars some debris loose from the intake to the petcock inside the fuel tank.
I would take the petcock off and see if it has debris blocking it.
Let us know how it goes.
