Tony Its a Q99 not correct for this model but probably still worked Should ideally be the later R55, During that period a Q77 or and Q88 were correct I would need to take the valve apart and see if the stem on the Q88 would screw into the fuel knob used to clean the generator tip
Thank you, @adelcoro. I thought it was a Q99, and therefore not the original fitting, but wanted to be sure. ?T88. Cheers Tony
