Any1 knw how to set a 4hp johnson outboard 2 start

hi i have a 4hp johnson outboard motor an old1 and dont knw what settings to put the dials that are on it too! theres a slow and fast dial and another1! any ideas i tryd starting it but the cord for the pulley started breaking so it in the shop gettng a new1

The low one is the idle jet , the high one the main jet , the other is probably the rpm adjuster , for the high and low clockwise = less fuel, anti= more fuel ,
try screwing them in all the way then back out 2 full turns (you might want to check out a forum on johnsons ) give plenty of rpm to get going . check spark and have fresh fuel . hope this helps .

Mightn't be a bad idea to remove the screws completely, make sure that the needles are clean, and drain the float bowl while you're at it.
The "right" position for the screws is a trial and error thing from my experience - they are tricky little devils, but once running right, and once you're used to tweaking them, no problem.Not sure what "the other" is - the choke perhaps!(IIRC, that's just a little square section rod which pulls out, then there's a lever throttle below).
Good luck with replacing the cord - that can get very messy if you let the spring unwind.
Due to my lack of decent maintenance, the brass mixture needles corroded and seized in the carb housing in my small Johnson.Couldn't turn them, and couldn't free them up with heat, and as I found out, they snap off easily if you force them.I'm not sure what's recommended, but a smidgen of good grease on the threads might be a good idea.

How old! Got an original manual for one if it's the right version.
