Cant Start w/out Starting Fluid

[Hardcore]

got this wierd problem all of a sudden with my 1990 150 yamaha 2 stroke. has always started easily. now it wont start. i have spark and the plugs are wet. if i shoot some starting fluid in it it will fire right up and keep running great as always. if i shut it off it will start back up fine within a couple hours. after that, it wont start again. any ideas on this?

Re: Cant Start w/out Starting Fluid

Check to make sure your choke is closing all of the way when you hit the switch.

Also are you pumping up the primer bulb before hitting starter?
Could be bowls are not full of fuel
