Hi, I live in the UK, and have had some starting problems on my AN400Y. It has been 'sluggish' at times to turn over, and so I bought a new battery. Although this helpped a little, it was still 'sluggish' from time to time. As my journey to work is quite short, I also bought an optimate to help keep the charge up during the week. This week however she would not start, just turned over very slowly, however come the evening (temprature below zero) and a jump from a car she caught and fired first time. Somebody over here mentioned the automatic de-compressor, have any of you guy/gals any thoughts on the matter, before I get stung by the service agent. 8)
