Alright. Since I got the 19mm delly stage 6 carb on my scoot it's been a pain to sstart sometimes. I sometimes need to adjust both mixture screws to get it to start, some times I can leave it for days and it will start first time. Or i could ride it to work do my shift and have to fiddle with the mixture. its done this with all different jet sizes any advice would be great ta.
Can you extrapolate i don't see what more i can do if it cab run well for days than suddenly need tweaked
