1997 200hp Yamaha 2 stroke stalls right after startup

My 1997 200hp Yamaha 2 stroke stalls right after startup. I really have not used it this year and started it memorial day weekend and it ran but a little rough figured it was the winterizing. Now just over a month I start it and it will not stay running for more than 2 seconds. start it high low speed same. I'm guessing it's the fuel again this ethanol is such crap. I put lots of stabil and starton .
Update: will stay running if manual choke on

choke says you need to clean carbs

Yea that's what I was thinking. I had the carbs totally rebuilt 2 years ago, $2000, would have sold boat if the guy gave me anything close to that as an estimate. Probably have like 10hrs on them. I sprayed some carb cleaner in while running. Any short cut to cleaning them besides removal and totally disassembly?

Nope ...

takes about 1.5 hours to do the job.
2 hours if you stop for coffee.
labor is typically 150 or so plus any gaskets.
typically the only gasket required is the fuel bowl gasket.
typically as the ONLY part of the carb that stores fuel is the bowl there is no point in removing the pilot air jets nor the bowl vent jets.

I would think you got shafted on the $2000 unless they had to drain and clean tanks, dispose of fuel, plus clean carbs and replace lines and pumps
