hi,

since I got my GQ, the idle speed has been a bit high. It generally stays around 1100rpm and only occassionally drops to 800rpm. The engine speed 'knob' is pushed all the way in and there's plenty of slack in the cable. I've tried adjusting the screw under the throttle cam, but unscrewing it all the way makes no difference. I haven't really noticed a pattern of when it drops to 800rpm, but it's possibly when the engine is much hotter (ie. driving in traffic in high temps). I don't know if it's related, but my temperature guage only goes up to a 1/4, unless I'm standing in traffic at 30C+.
Is there another way to adjust the idle speed? The engine is a TB42E. The idle speed is the same whether running on gas or petrol.
Thanks for any suggestions.
