Tempo handy. 56 or 57 I think. It has a saches motor. 2 speed. Not sure it has any restrictor. Or brakes...
sorry............... That little engine was over engineered anyway, so it should cope with it. Measure the current normal compression psi, before machining the head. Then do the machine work, fit it and measure the compression psi again to get the new figure. Then you should be able to calculate the increase in compression as a percentage of the overall. You could play it safe at first and machine 0.5mm off the head to see what figure that gives, then you can calculate what it would probably be with the full 3mm off it.
Had a baking day. Christmas cake, gingerbread house and Yorkshire puds. Boiling the potatoes ready to roast tomorrow.
Been going through the wiring of the tomos, looks like its got a reg/rec and not just a regulator. Which means I can run 12v DC. Good stuff.
Cdi has crapped out on me I think.... "Ran when parked"... hahaaaa Buggery. However. Its 90 per cent done now. Just needs fluids and fettling. And a spark.
Had a nice run on the cub today. Needs a service bad. Also needs a sprocket carrier bearing.... Still not worked out why the tomos wont spark. Must be the cdi.
Took the bmw to Bergen for a heart scan. My heart is fine (as usual, eat vegan, don't die). The bmw has been only trouble...
