OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Victa Two Stroke Engines Bad Knocking Noise

This mower has had a bad knocking noise and today died, it would seem the head gasket may be blown. i may just put a different motor on it


seems to be leaking from the head

Probably just a worn gudgeon pin.
You cant just re-engine that so easily. It runs a longer crank than your regular 18" two stroke.

Thanks for the reply bigted. i have 2 of these mowers and the other one has a cracked frame where it meets the handle so i may canibalise it. how hard is it to fix the gudgeon pin problem? thanks

Fairly simple, remove the head, take starter off, remove bolt that holds conrod on and replace the piston, rings and rod as a whole unit. That'd be the easiest way assuming you have a good used piston there.

thanks mate i didnt really want to part the working motor from a working mower i have a few spare motors. thanks for the reply mate. i like the mulching capabilities of these mowers

Chinese made crap.

I'd just strip it down for parts mate. Win some, lose some. I'm sure you can sort something out though. Maybe mount a spare powertorque upside down and turn it into a helicopter. A REAL hover mower ... Paint it camo and mount a couple of machine guns on the handles. Keep the stray cats away from your yard. Just need to make it all remote control ...

If anyone could / would do it it'd be you.

its only the internals need to be swapped over mate . just take a good look in there be sure the bore isnt beyond it too or you will be swapping cranks over . might be your first full rebuild !!
not too tough a job just look and take it slowly as always

thanks for the input dave but i recon ihatewetsocks has something. i was going to swap the motors over
so i will do that first rebuild later than sooner man
well i am halfway through my next project.
anyone have any really big fan blades?

That oily buildup is completely normal and i suspect unrelated to your knocking. Have you checked blade disc/boss? Running lean and pinging? Personally other than scuffed pistons/bores not much goes wrong internally with these motors.
