Could someone help me please? I have a petter a11 and had to remove the valves because of low compression. They came out easy enough but I can’t get them back in. Do I need specialist tools? ⚒

You might need a valve spring compressor.

I've had plenty of success with these:    https://www.ebay.co.uk/itm/176297958035
Other similar compressors are available. What diameter are the springs?

You're welcome.
If you give us the diameter of the springs I can check that they will fit in B&S tool

I’ve been working on our Petter a11 and found that we need a replacement piston ring. Does anyone know where I can find one? Many thanks to you all, Martin and Paul.

Size (diam + thickness + width ) would be useful

Maybe try: Stationary Engine Parts, FW Thornton, Cox & Turner ?

Hello thanks for your help I will try to get the information for the piston rings. Also will have a look at where you recommend. Thanks again, Martin and Paul.
