G'day Alan and Mf
I don't think the motor is worth buying at that price unless you had a mower needing parts and the parts rarely
come up for sale ,as you say Alan the top mount for the cowl is broken and that is part of the top crank case
so you would have to weld or replace the crank case at extra cost.
Doesn't look like Victa is much in demand in England ,you would buy a complete Victa cheaper or pay a
little more than what the motor is selling for to get a complete mower.
The Victa motor has had 37 Views probably 20 from here so not a lot of interest.
Gumtree UK may be worth using and Setting alerts for your searches for victa and never miss a new ad in your area.
