Hi I'm a first timer. Have a Lawn Hornet that has started to cut out. Started Alright this morning. ran for approx 5-6mins then just "died". Primed Bulb fired up,when I depressed "trigger" unit ran sluggishly then cutout. Let it stand for approx 1hr(finished off mowing) Primed etc same thing happened Started,Depressed Trigger ran sluggish then "died'. I'm not mechanically minded but gotta start somewhere. Any suggestions .....?
