Gee thanks, Rodeobob!
Yep the one on the left is the same as mine - nice to see your other mowers too.

When I pulled the head off the other day, I also pulled the cover plate off that accesses the vlave stems and springs. The guides seemed to be pretty firm - at least there was no slop in the stems. The valve heads were pretty coked up, but I persevered with a hard plastec scaper and got most of the gunk off the seats and faces. I may need to put some grinding paste on the seats and cut the faces/seats in. Just want to get it running first if I can - of course I may need to do the valves for that to happen!

I will be off to do a round of the Bendigo tips and mower shops over the weekend to see if I can pick up a cheap Magnetron type coil. Will also get some time at the weekend to start the renovation thread and put the pics up that I have taken.

Thanks again for the photo of your mowers.
