Had a fuel deliver issue caused by the chinesium fuel line kinking and the fuel filter clunk exploding inside the tank. Found a hunk of good 'ol black fuel line and a new clunk (different style), and it fired up straight away. Tuned the mixture screws, there are both high and low, and it's running great. I set the high end to right where it switches from four stroke to two. Using VP 40:1 fuel. The clutch thing doesn't seem right. I'm going to see if there are any real-deal Homelite parts kicking around on eBay. That will be the last think this old relic needs.
