tecumseh carburetor

I have a toro snowblower with a tecumseh engine and having a carb problem. Had trouble with surging and couldn't get it adjusted so I rebuilt the carb and set the float level with the carb body and started the engine and adjusted the mixture screws as they say and it runs fine but I can't get it to start as they say it should. I prime the engine 3 times and have the choke fully closed and it won't start.If I open the choke a little and don't prime the engine at all I can get it started but I'm wondering why I can't get it back to tecumseh's way of starting it. I have to imediately open the choke all the way as soon as it starts. This carb has the power adjustment screw under the bowl and also a idle mixture screw and idle speed screw. Can you give me any ideas?

Hard-Starting Snowblower


Re-set the float heighth to Tecumseh specs, which is NOT LEVEL
with the carb body. This actually is REDUCING the amount of fuel
the float is allowing the needle/seat to let pass through. The
CORRECT setting is just below level, or CLOSER to the carb body
than farther away. If you have a 11/64 drill bit in your tool box,
lay it across the face of the carb opposite side from the float
hinge pin. Bend the tang on the float touching the top of the
needle to where the outer edge of the float just touches the
drill bit. This will be correct float position. See if that doesn't
improve starting for you.
