had a tick over of 1K yesterday, normally have 800 or lower if I want. nothing changed bar oil change and tappet set. so found it unusual, mag check ok. I pulled the choke out while running, the motor dipped then ran quite rough. I would assume it should of cut instantly if there was no air leak, so I assume there is a leak on the inlet, poss a small 1 to increase the tick over. 2 years ago I changed the rubber that had a split, the symptoms for this were quite severe.
so wondering if the rubber is on its way out again, any thoughts
