Hello everybody. I am new to this site.

I have a. Atco commadore B20 cylinder mower...it has the g221p Mitsubishi engine on.

recently the head gasket went....wore a hole through gasket.

i have been trying to find a replacement gasket but am struggling. Wondering if anyone can help?

if not I am looking to replace the engine completely...all I know is the shaft is a 5/8.

just struggling to find a new engine to replace it.

anyone have any suggestions on finding a engine?

any help will be good thank you.

regards sam

A photo of the mower will help . If its the age I think then I believe the Atco 114 cc gold engine will be a sraight swop but you will need the 114cc engine  3 legged clutch drive as the crank is 3/4 inch . This is not as powerful but I d guess if the grass is not too long will work ok . Have you tried the Lanwmower centre at Hailsham for a head gasket though as this would be easier?

I have a Atco Balmoral 14 inch this had a poor engine on I think the maker's name started with a "T" but anyway I changed it for a Honda Engine. I think the only modifications was to shorten the drive shaft and drill a couple of new fixing holes, but it works a treat now.
