Why does an engine surge? Original Message Jan 2, 2012 6:40 pm
I started up my 11.5hp Tecumseh powered Ariens and it was surging. Never did that before. I'm not sure what causes an engine to surge/hunt but here what I did so far in an attempt to correct it. I changed the spark plug, took off and cleaned the carb bowl and needle and float assembly. Cleaned the jets with carb cleaner and ran a fine wire through every hole...even the tiny one. It still surges. Any ideas on what else I should try...or re-try.
