sounds like the one way clutch bearning is going out you need to take bike to a shop to fix

If it sat for a year without Sta-bil in the gas it is probably gummed up and you will have to remove the carb and clean the gunk out of the inside of it and check out all the passageways to make sure they are clean and open

You need to set the valves.

yamaha 50 vino scooter, it sat for a year, i got a new battery, and give it a shot of starting fluid, it starts but gradually dies, whether i give any throttle or not

I found a maual online at:

let it dry out and kick it over a few times with the plug out. it should start fine when dry.

Might be the wrong jetting, or possibly spark plug gap is not correct.

back fire through carb when you let off gas have to run with choke on

if its getting hot try checking the coil, And if not then try running some carb cleaner in it or rebuild the carb, but there could be a few more reasons why its doing that but try that first. hope i was of help to you/

it may be flooding out that is why it wont start try to shut the fuel off and try to see if it will try to start if not try taking the spark plug out and putting a little bit a very little bit of gas in the plug hole and then put the plug back in it and try to start it

put a thin layer of grease in the bearing race/concave part where they go. If they have a retainer pop each ball back into the retainer, test fit all before grease goes in. Make sure that it all fits smoothly, and snug not too tight. If the balls themself are out of the retainer they will pop back in fairly easy and the retainer can also be bent back into place to keep the ball bearings in place.

lean gas mixture. or the valve timing is off, but probably both. A lean mix will run really hot and allow for secondary combustion in the pipes (backfire) when the valves let even a bit of uncombusted gas through. My guess is that the bike hasn't had the carbs cleaned out thoroughly in a while. Run a half can of Sea Foam with your full tank of gas to help clean out the carbs, but really you should take them apart and dip them to clean everything out. Also you could adjust your pilot screw settings to make it run a bit more rich, but then you are just compensating for the dirty carbs. That's just my guess.

If there is any gas flowing out of a Mountain Bike you have serious problems.

In reality you have a Motorcycle, not a Mountain Bike.

It's almost surely a stuck float valve. Try banging on the float bowl with a rubber mallet, but not too hard. You should really take off the bowls and clean them out, then replace the float valve pins and check the floats for any holes or for sticking action. Sometimes the floats will stick open due to rust gunk or old gas gummed up in there. I use Sea Foam fuel additive to help keep the carb clean. You could try running a half bottle of that through a bit, but I'd start by getting that bugger unstuck first.

Carbs need to come off and pilot jets need clean!

the spark plug gap is the gap at the end of the spark plug between the eletriode at the end of the white bit to space this you need a tool called a fealer gauge you can get this at a tool shop hope i have been some help

hi mate disconnect the cut out switch and try kicking it over if still no spark check connections are pushed together propally there buggers sometimes and push the plug to the cdi in also consider replacing spark plug and try the coil on a different bike and see if it works goood luck
