Hello
MickyDI think I have located a decent parts list for your Pope engine: -
https://www.outdoorking-forum.com.au/forum/u...203-the-deluxe-pope-c1972.html#Post89461An image of your throttle set-up might help members understand the issue.
Essentially, you are not getting good throttle response.
If you can manipulate the throttle butterfly with your fingers,
and get good response, would indicate some linkage problem.
Hope this helps.----------------------------
