Car starts easily. The gears are brand new. the tires are 26". The exhaust is new. The tach is cheap, it could be out. No back fire, sputtering or strange noises, it just "lays over", I am thinking it is valve float but not sure. Carb could be an issue will check it out as well this weekend.
With valve float, I would expect some irregular 'noises' as cylinders misfill and misfire. (At least that is what I have heard in the very, very few times I managed to float anything; it gets kinda ragged sounding.)
