With the cooler weather I felt like the 1.8 four with Carb was running rough and there was hesitation applying full throttle. Time for a tune up was my first conclusion.
But before committing to a tune up I pulled the air filter off and sprayed some carb cleaner into the carb. I notice a brownish coating inside the carb and the cleaner washed it out. No need to go any further, it was a $2 fix.
