260 mercruiser floods and stalls when i throttle down to idle when engine is warm

[favaluuch]

i have wellcraft with a 260 mercruiser engine. the engine runs well and the boat planes off without issue. When i throttle down after running for while, the engine stalls and appears to flood the carb. i have to wait 5 minutes or so then crank it over several times before it will start. once it starts it runs well again. any suggestions? carb adjustment? throttle cable.
