[jetfest]

hey guys i just am wrapping up my ski build i added a wetpipe, jsu head, blowsion fa's i rejetted the carbs with the jets supplied and also added t adjustment screws. when i go to start the ski it cranks fine but wont fire up. when i pull the fuel return line off at the carbs i get a burst of air coming out. and when i pull the fuel in line off no gas comes spraying out so i believe theres a problem there plz help

Will it start if you pour fuel into the carb?

 

[jetfest]

yes sorry forgot to mention that

have you tried cranking while cupping the tops of the carbs for a second or 2 to see if fuel rushes into the carb bores?

 

[jetfest]

no how do i do that

 

[sflsurfrider]

take the flame arrestor off and put your hand (or a rag) on top of each carb and crank the starter briefly once or twice.

when you remove the rags, there should be fuel visible when you remove the rags.

make sure you dont have the feed and return reversed on the carbs (obviously).

there is no fuel getting there
