With it idleing as best you can, spray choke cleaner around the clutch and mag seals. If it's leaking it will suck it in and rev up some. I've changed some in Kawasaki engines and I drill a hole in the seal and use a slide hammer to pop it out. Then lube the new seal and tap it in around the edges if they need replaced. Double check your carbs and make sure "all" the jets and passages are clean. I use a drill bit to clean the jets. Just twirl it in your fingers to remove the crusty crap.

Check your carb boots between the carbs and the block for holes/tears. (sucking in too much air) this might be why it will run with the choke on. Cheers.
