Hi, seem to be having a bit of trouble changing the coil in a Villiers 197cc 6e engine, it just refuses to let go from the ears. Are there any grub screws or the like or am i just a wimp and not putting enough brute strength behind it. If there are grub screws i should have gone to specsavers. Someone come to my rescue.

The factory did not fit grub screws as you suspect. As standard the ears are just a hand push fit but they can have a hefty build up of muck and corrosion which makes them stiff to pull off.
Having said that as this push fit can become a little sloppy after replacing the coil I then fit a grub screw on each ear. This ensures a good connection. It's possible someone may have done this already.
Ages ago I bought a few packets of 3mm grub screws plus the relevant tapping drill and tap from a model shop specialising in radio controlled racing cars. They weren't expensive.
Have fun.

Thanks 33d6 new coil now in place. Turns out i was a wimp.

The other standard trick with Villiers coils is to discard the Bakelite HT lead connector thing that connects the HT lead to the coil and solder the HT lead directly on to the coil. That removes another trouble spot.
The bakelite connector was necessary back in the days when HT leads had rubber and cotton fabric insulation because that sort of insulation failed so quickly but with modern non rotting plastic insulation it's not the problem it once was.
Cheers,
