Husqvarna LT112 Ride-On Lawn Mower Briggs & Stratton 12hp Engine

  
This is a project I've been working on for 12 months or so and no longer have the time to commit to it. Will try and describe as best I can but will accept questions and do my best to respond. I have swapped the engine on this from the original 10hp which I also still have. Currently fitted is a Briggs and Stratton 12hp which will start and run but has misfires/backfires. It has had a new battery, new solenoid, new throttle cable and new carburettor. The exhaust I have tried to get to fit the engine but the engine cover will no longer fit over it, some fabrication maybe required. The choke isn't working properly and the gearbox may need some investigation. I have also sprayed the frame and engine cover in black instead of the original faded orange.

Has a small amount of petrol and oil in it. Has never had a cutting deck as it was going to be used for towing equipment at my local cricket club.
