I love to fix these small engines but this one has got me stumped. Any ideas greatly appreciated. Its a 10 year old Weed Eater leaf blower. Just stopped cold and will not even fire. Spark good, compression over 100, new carburetor which was installed before shutdown and ran good and just to insure it wasn't stopped up I have flushed it with carb cleaner in all passages. New flywheel with key. Cylinder bolts are tight, spark arrestor is clean. Tried starting fluid in cylinder and carb but nothing will make this engine fire. I don't want to let this thing beat me.
