I was under the impression that the oil pump drive turned at 1/2

the

e-shaft

rate.  When you say that the pump was run with an electric motor

at

6000

RPM

crank speed, are you turning the pump drive at 3000 rpm?  I will

be

using

your pump drive and external reservoir on my engine ( which I

just

received

from Bruce Turrentine)

This is correct, the pump does run at half crank speed, however, it
obviously has no meaning for running the engine. The only place

you can influence the flow rate is the throttle linkage.

Richard,
I think the confusion here revolves around why you chose to spin the

metering

pump at 6000 RPMs during your test when it will only rotate at 3000 RPM
during a 6000 RPM engine run.  Wouldn't it have been more realistic to

have

choosen 3000 RPM for the metering pump speed during this test??  I (we)

may

not really understand exactly how you conducted the test !!!  Can you

clarify

this for us??  I will also be using the metering pump adapter to deliver

2

cycle oil to my 20B.  I'll be ordering the metering pump adapter any

day.

Thanks,
Don Mitchell

Hi Don.

I did not spin the pump at 6000RPM! But for some one using the adapter in
the engine, it does not matter how fast the pump is actually running. all
it depends on is how much oil the pump delivers at a certain engine speed.
Sorry, if my test description did not point this out more clearly.
