I can start the motor with the warm up lever and let it run for a while. But once I close the warm-up lever, it sputters and dies everytime. Carbs recently cleaned at repair shop. Good gas. Help !!
1st thought is that either the linkage is out of adjustment or they didn't do a very good job of cleaning those carbs or the fuel hoses are in need of replacement and the carbs are fouled again.
