Cold start problem B&S 24HP Simlicity Regent ride-on mower

OK you got it, it's an air leak on the right-hand side of the carb manifold. Engine starts staggering on tick over when manifold flooded with CRC.

Was leaning towards an air leak this morning when reading another thread and have done the same with my motorcycle carb manifolds previously but for some reason I never thought to apply the same to my lawnmower. Thanks a lot. Cleared up a mystery.

Glad that it is sorted.
Very important for you to monitor the exhaust valve lash for the next season as you have been running lean and may hove softened a head.
