Got a newer Briggs 750 DOV on Husqvarna LC18 mower, which has an automatic choke. Consistently takes 3-4 pulls to start from cold, but runs great, restarts hot ok. I've had a thorough inspection of the carb and the only thing i can find is the actual choke butterfly is such a poor fit/too small even when fully closed there are large gaps all around it. Tried what i could, gave up and ordered a brand new genuine carb hoping it would be better. Of course it's exactly the same 2-4 pulls to start cold, anyone else had experience with this? Carb does not appear adjustable in anyway to try compensate for this.
