Z400 carb winter tuning

[buzzy613]

alright boys and girls yeller is not liking the cold weather. she dont want to fire up so i dont think its gettin enough fuel on the pilot or starter jet, i have the fule screw at 2.5 out 165 main i think, 72.5 starter jet and i cant think of the pilot. ill pull it apart tomarrow but any body got an idea on what to richin up? itll cough through the carb when i have the coke on but no start up

squirt some fuel through the intake or starting fluid in her and makes sure she fires up. Because its possible that it could have lost spark

 

[buzzy613]

if it lost spark then why would i be asking questions about jetting? it still has spark, i killed my battery runnin the starter, pull started it fired right up and warm fires right up also i think the idle cuicit is lean because of the coughing through the carb
