The needle valve in the carburetor is allowing gas to seep into the crank case while it's just sitting there and as soon as you pull the start cord, all the gas gets sucked into the piston/cylinder.
You need to have your carburetor rebuilt.1997 ski doo formula z If i do not throttle it immediatlly after the first pull it floods out ?
hi there,,, Mr Knowitall is correct. you need to rebuild your carb.
Whats happening is the float is stiking down thus allowing the float bowl to flood... Its an easy job. Go to the local boat store and get a carb rebuild kit. You will get the needle and all the gaskets for the carb.
You take it off carefully take it apart... clean the bowl, the jets ( the needles with carb cleaner. Check the float to make sure it isnt gas logged .. that is full of gasoline so it wont float. then check the needle. which is held in by the float. suirt carb cleaner through all the needle seats and then if you can clean with compressed air... ( one of those used to clean a computer will do. then reassemble and put it back on the engine make sure you have replaced the gaskets with the ones that come with the carb kit... You can leave it to soak over night in the carb cleaner if you want to before you put it back together and back on...
you will have to reset the needles to get it to idle but its not difficult.. buy the workshop manual for your motor and you will find it a breeze...
If you want to tru a quick fix that might work... squirt WD40 into the carb start the motor and see if that works... also .. take off the fuel line and squirt wd40 into the carb that way....
You could squirt carb cleaner into the carb before you take it off and run to see if it removes the needle blockage. Some mechanics dont recomend this as the carb cleaner will strip the oil off the cylinder walls.
I have done this but befor i started the engine I quirted premix into the cylinders and into the carb too.
Good luck...
