Honda Spree and Elite 50 Forums

I have a 84 spree with a carb problem, fuel is running out he overflow really bad, this is a newly rebuilt carb never been on my spree before ,I had this exact same problem twice before it took me going through 2 carbs and cleaning and rebuilding them to get it to stop, lasted about 18 mo. started overflowing again thats when I bought this present carb and am having same problem, is there something else that could cause this? I cant believe 3 carbs would have same issues. Mick

Maybe your petcock is stuck open allowing gas to flow too much to the carb. Gas is only suppose to flow to the carb when engine is running. Petcock is suppose to close once engine is off and no vacuum is present.

Is the petcock cleanable or rebuildable if its diaphram operated wouldnt be better to replace it?

I had this same problem. It was a tiny piece of debris interfering with the float needle. If, however, it occurs with different carbs, it may be the petcock. Have you tested it by sucking on the vacuum line?

The best way to test the petcock is to disconnect the fuel line and crank the engine over, gas should come out at a decent rate.

I pulled the fuel line I have fuel flow all the time, Mick

I should have said I have fuel flow all the time even when its not cranking just sitting still

You have a blown petcock, make sure it isnt flowing fuel down the vacuum port.

Can they be repaird or do you just replace?

Replace it.
