tunning 253 red motor

[Nackerz]

Hey guys im having a bit of trouble tunning up my 253 any ideas?

i know timing could be out as i dont have a timing light and the carb will need tuning too....it has 2 screws on it at the bottom...

im pretty sure one screw is for idle mixture and the other screw is for under load mixture??

correct me if im wrong peoples!

Cheers for the help in advanced my fellow buddy's lol

if its a standard carb theres not much u can do apart from checking float level, make sure accelarator pump works and adjust idle mixture screws! as for ignition timing without a light all u can do is start turning dizzy anticlockwise alittle bit at a time and c how its goes! it should start to idle a bit quicker as u turn it and feel abit more responsive as u crack the the throttle.if it starts to ping abit as u drive it up ahill or at full throttle just wind the dizzy back a bit until your happy. bit of trail and error without timing light.
