Sounds like you might have too much oil in the sump or a wet sumped ( had a engine flooding )
does the oil in sump smell like petrol and runs like water if you tip some out ? if carb is not shutting of fuel flow
if so drain and refill to correct level andgive tank and carb a thourgh clean out and check / replace needle and seat in carb, check float for fuel inside float ?

then check that breather is not stuck closed and is allowing pressure build up in crankcase and forcing oil past rings into the combustion chamber

is the oil comming out of muffler ?or from somewhere else ?

check for a tight inlet or exhaust valve

have look and let me know what you find

I pulled out the pug to recharge the starter for key start, and lost the outer plastic casing to plug it back in. Can I order the casing for the exposed prongs


The 10640 model does not have an electric start that I can see. Are you sure you have to model number correct? The 10642 and 10642C models are electric start. I will use the 10642 as a parts reference.

The electrical assembly is here:

Where did you pull the wires out from? The battery box? The mower harness? The switch?
From looking at the parts available you should be able to figure out which part you need to replace.

Have a victa lawnmower 4 stroke engine when i started it recently it spits out oil and overheats pretty quickly its only 6 months old. checked oil it was full but i tried to turn it on again the same...


Check that the oil level is not too high, further than that do not do anything. As far as I can remember, Victas have a one year guarantee. Rather than try to repair it or look into it, call the dealer or take it back to him as you will invalidate your warranty if you do anything to the unit, and that is not worth it. Let the dealer worry about it.

Large rattle in the engine, No oil leaks, belts re


Take the serpentine belt off the engine and and run it without it for a couple of minutes. Did the noise go away. If it did then it's accessory related if not it's engine related. Possibly a stuck lifter. Just spit balling here. Need more info.
