Hello,
I had the same problem as you a long time ago.
For me it was just that the temperature was not high enough. For an alpha Stirling you need a very high temperature, more than 400 ° C.
You can help this engine run and put a iron wool in the base of the hot syringe. This helps the gas to take the hot temperature. You should also use a flame.
This video can help you, there is a very complete pdf to download in the description

I think the copper tubing (typically this type engine uses plastic tubing) might be a problem. Copper conducts heat almost instantaneously. The plastic conducts heat, not at all.
