Run a generator with a motor Answered

I have a 1.5kva gas engine generator but the engine part broke down. I opened it up to see if it can be fixed but the cam and the piston were shredded to pieces. I tried to run the generator part to see if it still works by hooking it up to an angle grinder via pulleys and a belt. It did work but the grinder only lasted half an hour. What better ways can i run this generator off of? What motor can i use to take the place of that broken engine? The engine speed is 3600 rpm.

Old lawnmover motor, smal motorbike engine....
all you need is enough torque to make the generator spin and maybe a pulley system to match the required RPM.
Most generators also have a speed control to keep the RPMs even and steady throughout load changes, makes sense to incorporate this as well.

an old lawnmower engine might be a little tricky as most are a vertical shaft engine as opposed to a horizontal shaft, however you're correct with the speed control. its fairly easy to find an engine with an automatic governing system on it that maintains rpm and you can find some b&s engines for quite cheap and most would only need a carb clean and an adjustment. however should the output shaft of the engine be a different size you would obviously need an adapter of sorts to go between, other than that an engine should be fairly easy to drop in and just work.

Cylinder mower engines which are popular in Aus and the UK are horizontal shaft motors.
