1998 200 Johnson Venom Keeps Stalling

I have a 1998 Johnson Venom on a 1998 Ranger R91(19'9")

I have been having problems with it stalling out on me for 2 years now. It's hard to start in the mornings(I basically have to keep chocking it until it finally will stay idleing without stalling) and when I go to give it gas it will stall out before I get on plane. Sometimes I can put the throttle all the way forward without getting on plane then it will stall out.

I have taken it 2 places. The first tried to adjust the carburators becuase he said it sounds like it's missing every now and then. That did not help at all.

The second guy recently replaced the jets in the carburators to a bigger size. He said that the engine is getting plenty of oil and not enough gas. The boat does run better but is still hard to start in the mornings and still stalls out every now and then especially when I'm putting the it back on the trailer.

Does anyone have some suggestions as to what I need to do or look for to try to solve this problem?

I have an 87 200 on a 87 ranger that does the same thing, I have to pump the bulb every time before i start it. I can tell you more of what its not then I can what it is. I have replaced the fuel pump, rebuilt the carbs, put on new fuel lines, new primer bulb. water seperator, pickup tube in tank, reset all carb linkage,spark plugs. they say now that the spark advance my be off. If you find out what your problem is , please e-mail me at stantheman44@aol.com. PS I been working on johnsons for many years but this one has me stumped.Anyway I hope I saved you some time and expence. Stan.
