2001 summit hard to start

[dyllyn]

i have a 2001 summit highmark 800 im having a very hard time starting it....the last time i went snowmobiling i had to manually put gas in the cylinders to get it to fire up...as soon as the machine warms up it starts just fine....just the initial start is the problem....it definatley seems fuel related becuz soon as i add fuel to air box or cylinders i can get it to fire up......ive tried full choke 20 pulls half choke 20 pulls no choke twenty pulls....it seems to have no fuel from the get go....also the machine seems to run perfect once it finally starts and runs all day with no issues......any ideas where to start......any help would be appreciated thanx......

Verify that the choke is working properly

Had it happen to one the other day. The choke circuit could have a problem, in our case it was because the throttle was stuck on 25% and the throttle must be closed for the choke to work.
