I have a question about idle speed control on 'start' mode on my trimmer. The throttle isn't in any different position than in 'run' mode, so I'm not getting any additional throttle during starting. I have had my trimmer for 4-5 seasons, working solo, trimming out about 1,100 lawns per season. Last season, perhaps in May, I changed out the braided wire throttle control, running from the trigger to the carburetor. It worked fine for the rest of the season. During the off-season, I cleaned up the motor unit, not making any adjustments. This Spring, I'm not getting proper throttle during 'start' mode. I do not see any adjustment on the cable between the trigger catch mechanism and the carb. The braided wire has an attached ball that catches on a screw head, providing the force from the trigger to the carb lever. The wire continues beyond the screw head to a bolt on the starter, providing a ground. The engine speed is identical between the 'run' mode and the 'start' mode. This means I'm starting the engine at idle speed, which doesn't work very well. I'm having to manually hold the trigger while starting so that the engine has some throttle beyond idle. I've scoured the manual and I find no information. I see a Torx screw head from the top, but I find nothing in the manual about an adjustment for this screw. I've tried screwing it a half turn one way, then the other, but no difference. I have returned it to the original setting. When running, the engine runs great, good power, just as normal, and just as I would expect. I have an FC85 edger with exactly the same power head. I've set them side by side to compare, but see nothing different. However, when I have the trigger in 'start' mode, I see a small movement on the carb lever, unlike the trimmer. Anybody have this problem? If so, what is the fix? Thanks. P.S. Don't suggest the dealer -- they've done more damage to my gear than I would bother to share here.
