Without hi tech equipment a good way to tell if the main mixture is about right is with the choke open it should hesitate & bog when the engine is cold. Than run good after it warms up. To set the idle mixture turn the idle mixture screw in slowly till the engine starts to slow down. Then back it out till it runs good about 1/2 turn. Reading the plugs is also good. If the porcelan is black it shure is rich. If there is a little soot on the shell it,s a little rich.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
