I have now driven a couple of times with me new MST and from the first day had lots of fun but on day two had some probs. Thing is, for it to start the idling needs to be really high if I set it down it stalls. If I drive it on the high revs I have lots of white smoke boweling form oulet this means it is set too rich but if I lean it out in the slightest it does not want to start. The first day I went for a drive I changed to a no. 5 glowplug rcomended by my local. It says on the back a pack "No 5 Cold - for Nitro Fuel from 10 to 15 cc." It has a really thick ellement. The second day, when I had the problems, it was a bit colder day. My dealer said that might make a diferance in starts. [sm=drowning.gif]
