I'm having some trouble starting and keeping it at idle until it gets very warmed up. The last time was last night, I'm in the Phoenix area, around 1100 feet elevation, air temp between 60 and 70, not much humidity, and the last time it ran was about a week and a half ago.
First of all, it doesn't seem like the choke does much of anything, no matter what position it's in. I looked down at the carb before starting, and the choke cable is moving that black "rocker switch", but It doesn't seem like it's enriching when it's on.
To start and keep it running, I have to give it gas and rev it between 2k and 3k to keep it going, or else it dies. I need to keep doing this for a few minutes at least. Eventually once it warms up it will idle ok on it's own, as long as the idle is above 1700 or so.
I've seen the fuel needle adjustment on this site and have done a similar adjustment on my kawasaki's carb (Keihn CVK 34), but on my kawi's carb, there is a separate pilot jet that feeds the carb during idle, and the fuel needle doesn't come into play when it's idling. Is the GY200-5 carb different, and the main jet is also used for idling?
I guess I'm asking whether I should go ahead and do the fuel needle clip adjustment first, or start with other things like figuring out the choke, idle speed, air/fuel mixture, etc.
Thanks.
