Not likely the mixture is SET too lean, but it can lean out if the carb is being starved for gas.
Being it ran that long before the problem started, was the tank getting low?
If there is a fuel restriction it will get worse as the tank gets closer to empty, especially if it is a gravity flow or the pump is weak.
There is likely a screen in the fitting at the carb. Even though the carb is new, if there is contamination in the tank it can quickly clog. There is also a screen in the tank above the fuel valve, same thing, it may be clogged.
Check the screen at the carb, take the line loose at the carb, check the flow.
Be sure the tank cap is vented. Under certain conditions the tank can develop a vacuum holding back the fuel flow.
Another thing to check, next time it begins to falter feel the temperature of the coil. If it is considerably hotter than the surrounding components, as in too hot to keep your hand on, it can be failing.
Don't sell your self short, these fuel and ignition systems are designed to be simple and field serviceable. The biggest mistake people make is throwing parts at a problem without testing first. Not only is that expensive, it can compound problems!
