Re: Making a Harbor Freight engine look vintage/antique?
Have you seen Mrsfans briggs bikes? He tilts his engines about 45 deg, and has had years of use with no oil related problems.
I think you could tilt the Clone engines successfuly if you took the effort to figure out how to keep the oil level thesame distance from the crankshaft as it is in the stock positon. As long as the dipper hits the oil, yer good.
If you dont wanna fuss with a special manifold, you could use a diphram carb like on the old Tecumseh 2-strokes.
