Seen alot of different ways to start a car with manual choke, as said on here pull it out 1/2 and dont exceed 2-3k rpm where are others ive seen say pull it outthe whole way and start it with your foot held on the gas.
What would bethe conciquences of not pulling out the choke when starting? As I'm bound to forget to do it early on!
Engine would not start, then you remember, oh yes, this was not a diesel, that is what happens to me
But if you think about how choke operates, you might realize that touching throttle works actually against the choke and if there is need to touch the throttle then choke needs to be adjusted, especially part which increases rpm with choke applied, which in practice is same as pushing bit of throttle. Choke itself is as name implies, it chokes the carb air intake, turns butterfly valve so that there is very restricted air flow into engine and with choke you just adjust how much restriction there is going to be, also it does open a bit of throttle butterfly when pushed enough far.
When you have mixture set properly, so that it is no rich side, you really need to pull it full or almost full out to get engine easily started, but immediately after starting you can push it bit back in, depending from weather is how much.
Often however carbs have leaks, throttle butterfly shaft, carb base, etc, which are compensated by mixture screw and setting throttle butterfly opening too little with choke as otherwise it would be hard to start and poor to run, but when you have everything repaired and at their optimal setting, it will need choke bit longer and bit more than typical worn and leaky carb. That is at least my experience with my 360 as I did fixed leaks on that one. 343 could use bit of adjustments, but it is not too bad, mostly one way valve is what I'm planning to add into fuel line so that it would be bit easier to start next morning.
