Starting issues

The OEM tuning spec of 10 btdc was based on real gasoline. Todays fuel being what it is . The engine will start and run better with a base timing of 14 to 18 btdc

Redfish thanks for the info . I was told by the mechanic to pump it 3 times and it worked a couple times but it's hit and miss . I need a better percentage its for a 17 yo girl with no patients lol . I'll adjust timing and get back .
Thanks for the replies .
