Hello, I have a 2001 Yamaha Vino classic. I had carb rebuilt around 30 hours ago, then it sat without starting for around a year in Florida. Now seems like it isn;t getting enough gas to start. First crank it sounds like it might go, thereafter no gas. Is it the filter? Gs shut off valve , fuel pump petcock? There doesn't seem to be an obstruction in the gas line. Thanks!
Model: vino classic
took apart carb, took apart fuel petcock
since it sat for a year it sounds like it is time for another carb clean. the fuel that is being used today is low quality and it can gum up a carb in a month. so setting for a year the most common thing would be a carb clean.
yes they have a filter or screen in the fuel tank. it is a vacuum controlled fuel petcock

yes but how do you explaint the fuel starvation on second crank and after? Like its notgetting fuel?
could be the auto choke is letting a very small amount of fuel through in to the cylinder. did you pull the spark plug to see if oily, wet or dry?Jeff Policky41035.7724986111
what would each mean? oily = getting oil, wet gas= gas getting through or dry = obvious?
oily = getting oil, wet gas= gas getting through or dry = obvious
yes you are correct. it will be some oil on the plug but really saturated is not good. on my Yamaha 50is cc scooter (same motor) if it set a couple of weeks the unit hard to start. I can get it started if i keep at it or add a teaspoon of to the cylinder through the spark plug hole and it will run then. my scooter has a bad check valve in the oil pump and oil is not a good fuel so when i add fuel it runs then. if you will run then stop when fuel is added to the cylinder the carb is plugged from old fuel.
