Tec's and Briggs were designed to run level, yeah they run into hills and don't run at level going up a hill, on a level framed bike, but that degree is a minimal, to thro a flat head that far out, just ain't right, the frame I spoke of I bought off a friend, he had it running, and when I observed it "running" I felt sorry for the flat head, BRIGGS, that was on it, I can remember hearing it say it wasn't oiling properly, the great "splash", occurrs better when the "splash stick" comes into a cool pool of oil, and is not obtained at the angle the oil is leveled to on that style of bike, sure enuff, the funeral was a month or 2 later, somebody else got what was left of the motor, I got the frame for like 20 $, it is very low on the fix it list, may not do it at all!
