When working on a carb the best thing to have at hand is a good service manual
Remove the air cleaner assembly and back plate, detach the fuel pipe I do it at the tank, back off the cable adjusters at the handlebar, loosen big nut at back of choke mount bracket and slip the knob down and off the bracket
Pull the carb off the manifold and detach the control cables
Remove the 4 screws that hold the float bowl in place these are very soft metal and even with a good fitting screwdriver the heads can easily become damaged best to replace with allen head screws m4 x 12mm
Jets will now be accessible
whilst in the carb may be worth replacing the float needle as the tiops often harden and give problems
on reassembly ensure that the throttle and idle cables are correctly placed and adjusted
It may seem difficult thinking about it but after a few times of having the carb off it will seem fairly easy
But at every step consult the manual
