Gas stabilizer for Honda engines
As with the first post addressing your problem, I also suspect the carburetors are gummed up and need cleaning as he suggest. And, from your comments, I definitely think you need to find a qualified mechanic to fix the carbs. After the carbs are cleaned, each tank of gas needs gasoline stablizer to ensure no problems in the future. I have a 2003 Honda 50 hp engine that I purchased new in January, 2004. I typically run the engine from early March until late November. The other months of the year it is laid up and not run at all. However, regardless of whether it is being run or sitting idle, every tank of gasoline has gasoline stablizer added to it according to the stablizer manufacturers recommendations. I've not had any problems at all with the engine.
