starting problem

I repaired a snowmobile for a guy about a month ago and it sat in my garage for about a month. It started perfect when i fixed it and put it to the side and waited for him to come and pick it up.When he came to get it I went to start it and it wouldn't start.But I sprayed a little fuel in the spark plug hole and it fired up and ran well. I shut it off and it will start right up no problem now. What would cause it not to start after sitting for a while and then be alright again? It is a float style carb with a choke and it also has a fuel pump. Thanks in advance!!!!!

If the fuel is draining out of the bowl very slowly, or evaporating, it won't start until the fuel pump is able to deliver gas to the carb....mainly noticed on engines with mechanical fuel pumps. Also, if the choke valve is not seating fully it will do this, and if the intake valves don't have enough clearance it will do this. Check these things and let us know what you find!
