Hi, I recently picked up what I believe to be a Scott Bonnar model 33 lawnmower off the side of the road during a council rubbish collecfion.

I have absolutely zero mechanical knowledge currently but would like to restore it back to its former glory before using it to cut my lawn. Based on reading some posts here I believe it to be a mark 2 model as it has a belt and chain configuration.

The original engine I believe has been replaced with a briggs and stratton 475 series 148cc. It also has a Rover speed control switch. I will try to upload some pictures.

Although I haven't tried starting it yet, apart from the odd dents and scratches the mower seems to be in good condition for its age, except for a random bit of wire sticking out from the front of the engine.

My question is, what's the wire sticking out from the engine and where should I start in a restoration process from a complete novice prospective, I assume rust and dent removal would be the first steps before trying the mechanical side of things.



Kind regards
Mike

Hi Mike33,

That wire as shown in the parts list below it is the stop wire but you don't need to connect it as the throttle control on the motor has the stop connector there.
