Hi Murf.
Mine is the red Fire LX that has been at the AGM the last few years. I too use it as my daily commuting car. Answer to the range on a tank of fuel, I work on 350 miles commuting and 450 on a run but you may do better because my engine is a bit worn and isn't getting up to temperature properly these days either.
As to starting, I do two strokes of the throttle pedal, fairly full choke then turn the key. If you are bogging down pulling away from junctions then you are just putting the choke in too soon. Use the temperature guage to judge when to push the choke in and just experiment to find the right point for your car. Also I push the choke in in stages as the engine comes up to temperature.
I have a small cache of Fire LX spares and will always be delighted to give help in any way I can. I am not very regular on the forum but you can get me on my e-mail,
f.tierney@btinternet.comPlease consider bringing your Y10 to the AGM to save the committee the embarrasment of having to give me the Y10 concourse prize again!
