I have renewed all fuel lines on my Virginia 542 hedge cutter including the bubble and I have it going but it will not tick over like it did previously. I've tried turning the 2 screws H&L but to no avail. Could you
.advise me the correct way to adjust them. The idle screw has not been adjusted. It will only start on full throttle and keep going in high revs. If I ease throttle back it cuts out about half revs.
