Carbs - Cold Weather Starting Options

[Bulldog9]

Would appreciate any advice on techniques for starting cold and on cold days.

I know the DRLA/IDF does not have a choke, but what is a good reliable starting technique when starting cold, particularly on cold days?

I have the hot/warm start technique down, is a part throttle turn key and engine fires and runs well. This is how I start my CV carb's motorcycles, and works well for the 912, but on a COLD start, I feel like I either flood the motor, or it doesn't get enough fuel and needs to be cranked A LOT............

It also seems to me as though the fuel drains back out of the lines and into the tank and the pump has to refill they lines. I understand this is a low pressure system and pump, but almost feels like I need a check valve.

I had a heck of a time getting it to start on Sunday, was 35 degrees, cranked quite a bit and didn't catch at all, smelled flooded, so I held pedal to the floor and cranked again, it eventually caught and started and other than having to feather the throttle till warm, ran fine....

So, other than 2 pumps, then hold throttle part open and crank, what is a good cold start technique?
