As an addition to the other thread, `blessing in disguise`. The paraffin flush was quite clear.
So I filled it with the cheapo oil for an oil flush.
When kicking her over to check for scavenge return, these clicking sounds appear. The balls seem to be engaged with the cups.
I can feel something that seems to be a double click by feeling the exhaust tappets.
My original thought was piston hitting valve/s, but how?
Now some advice please.
This last rebuild needed new barrels, head refurbished...new guides, valves...etc.
I bought standard 650 valves, but I have no idea what what camshaft is fitted. IF someone has put a high lift camshaft in, would this cause the pistons to hit the valves? Are some valve stems shorter?
BTW, no scavenge...new oil pump out for inspection. It never rains...
