Hi NormK,
I followed your advice and found that the kill switch was the problem preventing my Victa from starting. I found that the rubber plug that goes into the side of the carby through the rubber boot was jamming inside when the cam was moved with the throttle cable.
As you said the the kill switch mechanism has been poorly designed and problematic so I decided to by-pass the kill switch mechanism by connecting a Narva micro push button switch connected to the two wires that normally go into the side of the carby.
After installation, my Victa started first go and has started without any problems since. Fingers crossed 🀞it will continue to start with every mow to come!
Bye bye the poorly designed old kill switch mechanism.🀬
Thank you again for your advice.
