mercury 3.3 trouble

I have a mercury 3.3 that will not run when in gear. I have some outboard knowledge, I've rebuilt the carb got the engine running well. It was running in gear well until today when I left the harbor and put the engine in gear and it would die when I gave it juice. I recently had the motor off the lower end to lube the gear shifter and replaced the gear oil and now this problem has ocurred. Any help!

Has it 'run well' at all since you serviced the lower unit? Will it continue to run if you choke it - even partially?

Will it "idle' in gear or does it stall immediately upon engaging the fwd gear? If it idles OK I'd guess the gearing is OK, and unfortunately this still sounds like a clogged jet situation despite having rebuilt the carb.

I agree with Faster, I had to clean my carb twice last weekend, it doesn't take but a tiny tiny speck to foul a jet or two

carb screw

I siphoned the gas out, sprayed the carb, put new gas in with marvels and took the engine out to the boat and the same deal. not throttling up in gear. I turned the carb screw all the way in and slowly backed it out until the engine was running smoothly and now it's golden. took a couple laps around the harbor. Thanks
