Hey y'all,

Thanks for any help in advance.

I bought a 1999 Sprint F/S 207 w/ a 1998 225 Johnson Venom a couple of months ago. Shortly after I bought it I started having trouble taking off. The Motor would bog down when I was trying to take off quickly ie pulling a tube/skier. I would have to give a little throttle back off, then some more throttle then back off then I could go full throttle. Also, associtated w/ this was a rough idle after the engine warmed up then was turned off for a few minutes. The problem has continued to get worse to the point the motor floods and won't even start. First start it will bust right off idle up then idle down, down, down until it quits. If I can keep it running long enough to get it up to full throttle is runs like a bat out of H**l.

I pulled the induction manifold and noticed fuel was running all over the place. The induction manifold is just coated w/ gas and oil on the inside. I've put new plugs in it; but I still need to adjust the carbs.

Motor is a 1998 225 Johnson Venom. Model# J225STLECS Serial: G 04510224
Carbs were made in Mexico 3/26/1998 #439510 <- this # is from a sticker on the carb.. turns out it's different on 3 of the carbs.


What are the adjustment settings on the floats. Can they become saturated? How much should they weigh? Mine weigh .2 oz.

Also where should the indicator be placed for the automatic/electric choke? The indicator on the valve stem will point from 12 o'clock to 6 o'clock in a clockwise motion.

Any other ideas on what is causing this flooding would be appreciated.

Thanks again. <br /><br />
