I have hit a problem with this GSX1100ET I am doing up, it’s been stored for the past 9 years and I thought I might as well sort it out. I have stripped the carbs, replaced the needle valves, set the float height, unblocked a few jets and put them back on.(and what a faff that was). It starts and runs great when its on choke but any throttle kills it dead. Ah Ha, must be mixture I checked No 1 sure enough it had been turned out 4 turns probably to compensate for the blocked pilot jets, The trouble is that the pilot screws on No’s 2 and 3 are solid. I cant move them either way, Has any one got any suggestions for shifting a brass screw in a ali casing without buggering it up.
