Answer
Hi Jim,

Excessive fuel consumption is usually the result of worn needle jets. Other causes my be gasoline leaking from overflow tubes on carburetors, defective fuel hoses, or other.

Describe the appearance of the spark plugs.

I suspect the carbs need minor tuning to restore proper performance. I'll need to know the colors of the spark plug insulators. I suspect the air-fuel mixture is a tad rich.
