Compression test?
#12
Thanks Bob

Tappets are good and valves are closing  / opening ok from a visual inspection, new springs. I've sprayed cold start into her and have achieved a fairly mighty backfire.
I dont want to try to much advance initially till I know where things are, but if I advance her I get a push back in the cranking.

Ill bench test the valves as has sat a while.

Pull the spark plugs out and put a teaspoon of petrol into the cylinders put the plugs back in and have a go at starting.
If it runs then stops you have no fuel getting in, you might find it will start and pull fuel through and keep running.

Thanks Dickie,

Will try this but will un mixed liquid petrol combust ? and wont the fuel be exhausted after first crank revolution?

Worth a try to eliminate issue i guess.

Steven


PS Still interested in what the expected reading would be for a cold compression test ?
