Re: help sq 4 wont run

Hi would forget the Amel carb. The suction from the running engine on the Amel slide will make the throttle very stiff to operate. Tried the Amel on one of my Square 4, and finally went back to the Solex with butterfly throttle control. Keith

Re: Plunger suspension ride height adjustment

I had to make up spacers to go under the top hat cover. It was difficult to compress down to start the domed nut. I made up a simple jig using a rack clamp. Cured my problem. Keith

Re: Mk11 Big End Shells STD

I have 6 NOS shells available here if they are any use to you. For the final pair, try Colin Reed-Aspley if Bruce hasn't got any since the shells are the same for the KH as the Square four.
