Hi, Got a bit of a problem with my piaggio Zip field bike, I haven't bothered to run it for a few months, so today I cleaned the plug, stuck fresh fuel in, ect, then tried to start it, no luck. Right, So I checked for a spark: Yep, nice strong blue spark, but the spark plugs dry?
So I grab a can of easy start, spray in to the inlet, and it fires up, runs for a moment, then cuts out. So it appears the problem lies with the fuel side of things, I cleaned the carb, and tried again, but still to no avail.
What do you think? why isn't fuel getting to the spark plug ?
Thanks for taking the time to read this, Jamie.

Blocked or kinked fuel lines, blocked fuel filter?

Hi

Is there any form of fuel pump on it?

All the best

Keith

Hi Jamie.
I had the same problem and it turned out the fuel tap was turned off. Sad

Is there a vacuum hose going to the tap that might be off or broke.

Paddy.

Hi, I thought this, so took a bit of fuel line, and an old tank and had it sat next to the bike "remotely", so that I could rule out fuel filters, and the fuel tap, the float bowl is filling nicely, and I also checked that the flow hight is right with a clear bit of piping (got to love carbs that have a drain screw and pipe attachment)
There is no Fuel pump Keith , no. Sad


Thanks, Jamie. Thumbs Up

Hi

Is there any compression? Unless the jets are thoroughly blocked then that is the only likely thing I can think of.

All the best

Keith

Yep, a lot of compression, blows my finger off the plug hole.
It's very odd, might try cleaning the carb (again)

Hi,
Take your carb off and make sure your reeds are all okay. Not bent or splitt.
They could be deciding not to let fuel into your engine.
