Hey guys kinda new to this but I will describe the problem the best I can.
It is a 2009 ruckus with all stock parts that sat for around 4-6 months and then this problem started occurring when we brought it back to life.
It has a really hard time starting when cold, but once it is warmed up it runs like a top. Even once I get it running to warm and shut it down, if I fire it up while it is still semi warm, it starts and runs easy.
When starting cold, it'll turn over with electric and kickstart (both work) and run for a couple of seconds and then die. When I start it again I have to barely hold down the throttle for about 3-5 minutes before it'll turn over and start really going.
I have replaced the gas, fuel filter, air filter, fuel pump, and battery, re-jetted the carb with new (stock) jets but I did not take the whole carb apart, and I just recently checked the spark plug (it was good) and valve shims but both the intake and exhaust shims were at the correct spacing, and lastly I even increased the idle screw on top of the carb to see if it would help but it did not. I am completely at a loss and have read just about every forum here to try and find the problem but to no avail.
Anyone have any ideas left?
All I have left to think of is stuff that I'm afraid to do- such as take apart the entire carb and check the choke, or adjust the air/fuel mixture screw.
Thanks in advance for any help.
