[QUOTE="tjcassar, post: 16559, member: 1916"] Hi, After John explained in detail the design features of the twin start pump, I now understand how it works. Your point as to how to recognize the effects of the twin start prompts me to confirm that mine is a single start pump. I am rather surprised how slow the pump returns oil from the sump. I would say that the rate of flow is less than say a 500 single like an Ariel Red hunter. I can try to measure the rate of flow on tick over maybe some data exists as to how much this should be with the engine warm!! But then, different oils give different results. I would say mine gives a blob of oil every two seconds on tick over engine cold. So, with a single start pump and no wires in the little holes. Now the question is, should I put the 20thou wire or not?? The hole is obviously larger than 20thou, mine probably is around 30thou. I know this as I have removed one bolt off the exhaust rocker and managed to place a 20thou piece of wire easily inside. Does this say anything?? Thank you for your support. Tony [/QUOTE]
