So I pulled out the mower to cut grass and would fired up then died so pulled again fired and died! Out of fuel, so fill it up and took a while to get going but it is surging massively had this before had it serviced and it still surged a little bit now it’s really surging! What can cause this air in system maybe dirt in carb?!

Cheers

Tried to add a vid but will try take a shorter 1 and add!!
