Just yesterday I passed a lady cradling her infant in her arms. Nothing wrong with that but she was driving a big SUV at the time. Which got me thinking that I need to tune up this MG in case I need to get out of her way in a hurry one day. This MG has got zero acceleration. Sure, you can get up to 70 mph no problem, but it takes a while.
I have got the ZS set up nicely, I believe. The spark plugs are a clean, very light chocolate brown. The dashpot oil is always up to the mark. Usually get about 23 mpg. So I think I will take a look at the ignition side of things. I've got the Pertronix with the Lucas Sports coil, so I think I'll experiment with the spark plug gap (upping it from 25 to 35 thou) but I have a feeling that is a waste of time.
Meanwhile, has anybody got any thoughts on the ignition timing - I've set it to the book with a timing light but I'm thinking it may need fine tuning. Is it just a matter of experimenting or is there a better way. For instance, let me quote from the Moss Motors TR3 catalog:
"Setting the ignition timing after a tune-up is simply done by adjusting the distributor for maximum R.P.M. and then retarding the timing to give a drop of 100 R.P.M in engine speed."
Anyways, my MG runs great. starts first time, etc, but when you put the hoof down, nothing happens except a leisurely increase in speed. I mean, at least my Toyota makes a big screaming noise when I do that.
