Tecumseh 2 stroke hi performance fuel system

[Frank ZX]

First post. I have a Tecumseh Hsk850 from a snow blower. I have it mounted on a old mobility scooter.
I've made a homemade expansion chamber and I have a Tillison HL360 carb on the way. I'll be using a 3qt aluminum fuel tank mounted up front. It will be roughly level with the carb. My question is do I need a fuel pump or a outboard type primer bulb for it to pull fuel?
If I need a pulse fuel pump, where do I get a pulse from? Intake manifold or crankcase?

IMO, (and maybe someone more qualified will overrule me), but, 2 strokes are pretty good at sucking...(wait!!! that didn't come out right!).... But, they draw in fuel by the negative pressure caused by the piston traveling downward. Now, so do 4 strokes,...to a point, but much more differently than 2 strokes.

Let me elaborate on my crazy theory....I think because of the location of the reed valves, 2 strokes have a much larger vacuum to start with than the 4 strokes tiny valve opening with just the compression space to start off.

I think this is one reason 2 strokes can scream. Of course, this is pure conjecture, but, I'm not an idiot... (well, depending on who you ask!)

The Tillotson HL360 has an in-built fuel pump , so you shouldnt need anything else .

And the pulse is usually drawn from the crankcase .
