Hi there. I was wondering I have a greenfield 28” ride on that I have finally managed to completely overhaul. It’s was running perfectly but I have had it sitting for about a month with starting it. Went to start it today and it’s surging really badly almost like there’s a ghost inside😁I’ve attached a video so everyone can see what’s going on. Just wondering if anyone knows what’s the problem is. Thanks in advance for the help. Sorry I can’t upload a video cos of the file type. In the photos the control arm moves quite vigorously and the engine surges abruptly and starts back firing
