Trouble starting Yamaha f40bet carb version
Hi I am having trouble starting my yamaha f40bet it's the carb version
The engine has trouble starting it turns over without firing for ages.
I turn her over for 5 seconds at a time then leaving her for a while and repeat.
After 5 or ten minutes of this she will start to fire then after a while longer she will run but rough.
Once warmed up she runs fine and will run fine all day but come back tomorrow and I'm back to square one.
I always use fresh fuel and run the carbs dry when done.
I checked the plugs they are fine but changed them anyway.
All 3 plugs are sparking fine.
Any ideas what I should look at next?
