Customer Question

My Husqvarna ride on 13hp motor keeps on backfiring like it has latent ignition problems. can you assist me with how to deal with this problem as it runs well for a brief period then farts and carries on. It is my my most used mower as it gets through gates where my larger mowers don't.

Engine make and model?

Sounds like a valve problem, valve is sticking, and when it does, the combustion back through valve causes the backfiring. Remove rocker cover and check valve operation.
