Not any more cold blooded than any other carbureted gasoline engine from back in the day. I have had motorcycles that were 25 years newer take as long or longer to "warm up", There's a reason that phrase "warm up" made its way into the American vocabulary in regards to the carbureted gasoline internal combustion engine. They need to "warm up", and the colder the engine and the ambient temperature is, the longer it needs to "warm up" before it will run well under load.
I have a 1973 gas 3 cylinder 4000 . In warm weather, above 40 degrees F. I can push the choke back in all the way right after it starts and then let it idle with no choke for a minute or so and it's ready to go.
When the temperature gets below 40 degrees, I need to push the choke half way in after starting and leave it there as it warms up some and then I can put the choke in all of the way, but it still needs to warm up some more after that before it's ready to be worked. The colder it is, the longer I need to leave it on half choke, and the longer it needs to warm up before I can work it.
My test is to move the throttle from idle up to 1800 rpms or so in one smooth movement of the throttle handle, and if it revs up without any stumbling or hesitation then it's ready to work. If it doesn't throttle up smoothly, I put it back down to idle and let it go another couple of minutes.
I've only run mine at temperatures as low as 30 degrees or so at the lowest, and it took a good 7 to 10 minutes or so before it was warmed up to where I could swing the throttle up from idle to 1800 rpms and have the engine smoothly rev up.
Working it hard before it has had a chance to warm up can result in a lot of partially burnt fuel, which will build up carbon deposits on the spark plugs and valves, and lead to poor running, which in turn will lead to more carbon buildup and eventually require more than routine maintenance to keep it running well, if at all.
