I am in the process of removing the pistons on my 750cc engine ( I have been a mechanic for 65 plus years and stripped & rebuilt loads of engines car, lorry & plant but never seen a engine like the 750cc ) its my first experience of this engine, at the bottom of the piston liner there is a metal piece that only lets the conrod push through in a certain position what is this metal for, what does it do, its like a extension of the liner.

thanks rubyman

Good morning, All

"Slack Alice" Simon here.

Identity change due to problems logging on.

My computer says "connection insecure" and doesn't like me logging on.

The site doesn't like my details and the "password reset" didn't work, told me I had tried too many times.

Hence the change in identity.

Anyone else having problems?

I expect it is me.


Cheers

Simon

My horn switch has stopped working as it is quite badly corroded. I have good power connectivity either side of the switch so I know this is my problem. Does anyone have a replacement please or knows of an alternative switch that will do the job? My switch is from a Ruby/Opal/Pearl.

Thanks for your help.

Matt

Can a Zenith 24T2, e.g., ex Ferguson T20 tractor, be used without modification on an RN?

Right just taken the zenith updraught of my wifes chummy as it started to loose all power and then picked up again... I assumed it was blocked jets...


Reassembled and fuel pours out.... seems to come out around the two jet cover nuts on the bottom and the ittle screw hole just up a bit from there..... not pucking out of the float chamber.....   could this still be flooding or gasket failure round screw hole and  jet covers....


Any advice gratefully received

Pete

I have recently seen on Facebook a photo of a Ruby,  BOX 715, that once belonged to my godfather. Is the  here perhaps, or does anyone know them and could put me in touch?
Thanks...

Lovely story !

Cheers, Tony.

In a recent thread I promised to post some pictures of the engine once in the car, my son Peter helped me to drop the unit into the car today, which naturally led to some photography. 

The engine has now run up to 8200 rpm and 7 pounds of boost, which must be a shock for the 1924 crankcase.

   
   
   
   
   
   
   
   

It is good to have a willing pair of hands to help out, I do feel lucky to have a 16 year old son who takes such a proactive interest.

Regards, Mark.
