That doesn't sound too much like simply a carb problem.

What are the reeds like? When were they replaced and what did you replace them with?

Meanwhile the start sometimes but not at others would have me looking at the pulse hole.

A common fault is to use a not-Tillotson gasket between carb and block, with the reed hole in the wrong place (or to use the old tillotson gasket but backwards so the hole is blocked)

Even with the right gasket and the hole apparently in line, I have seen partial blockages (once from a piece of tissue used to clean and protect the carb).

Then you can also put the reed block upside down so the pulse hole isn't where you thought it was.

(been there done all of those, including once getting the engine to run for testing at nearly 3/4 power with the pulse hole blocked. It ran for an hour before it suddenly stopped and would not restart.)

Finally, of course, if you have been working unsuccessfully on the engine for a while, you can fill the crankcase with fuel, so that no matter what you do, the mixture will always be wrong until the fuel is drained out of the case or used up.

Or, are you actually using the right method of starting. Lynxes and Leopards can require you to handchoke the engine on full throttle to start, with a swift removal of hand when it first fires, but then subsequently may not need a choke at all to restart.
