I kept the motor and drained the oil after it was hot Mf .If I throw the motor out in scrap I'd still keep the coil, starter and carby.
Yes the Sanlli wheels fit well on a Victa 18 Norm , one below I put some on many years ago ,from memory you just slightly drill them out.
I've had 10 to 20 Lawn Beetle mowers with the plastic base and always cut the base up and put it in the bin and at least 10 motors I've put on Victa PT rear discharge bases .
I don't remember ever picking up the 10 to 20 free Lawn beetle mowers and them not having a good filter with the cover ,this Lawn beetle I took the filter and cover off to spray some fuel into the carby to start the mower as there was oil in the combustion chamber.
I only look for mowers from places where the median house price is about 1. 2 million and up and they don't bother taking parts off.
If you want lots of free good mowers Norm, I'd go along the coast from Seaford to Mentone on hard rubbish days.
