spark timing at idle is about 7 I guess, but you need to see if it advances to maybe 25 if that is what your service manual calls for
just disconnected the pointer on the cdi at linkage and moved it by hand while motor was idling to see both were in spec, on my 1999 C40
I guess your 70 is like...
I would make sure the spark timing is in spec and that it advances in spec also, by using a timing light.
If a cylinder is not burning the fuel properly there will be some fuel/oil mix going out thru the exhaust.
very hard to make sure spark is happening on all plugs when there is loss of power...
I wonder if being tilted up allowed the oil pump pick up to suck air.
also does anyone know if the oil pressure sensor is a switch or maybe something that sends a variable signal telling how high the pressure is.
could be mapped to RPM and pressure being within a certain range
this motor has...
measure voltage on the battery terminals posts themselves and on the cable connectors on both ends of each cable.
maybe that will point to a bad connection
I would think you need to find out what the problem is.
something it leaking.
my guess is check valves on the oil system
as far as running the fuel out of a multiple Cylinder motor with multiple carbs means that some cylinders will be running lean or without oil and fuel because the lower...
my guess is the contacts inside the relay are burnt and not making good contact, but it could the brushes or other things in the T&T motor/pump binding up.
since the relay is clicking it seems the controls work
,I was talking about jumping the main power wires to the T&T motor
But you do need to disconnect those wires from the T&T relay since in the none energized state they go to ground.
this is for My 1999 40, but I quess it would the close to yours
I Not much help, but having a DVA and a manual would be the best way to troubleshoot.
the manual will tell you what the specs are for all of the inputs and outputs of CDI
I have no idea, since I never owned a 4 stroke Yam
but I would think it would not be the same as a suzuki as far as specs but I could be wrong.
kills switch should take out all spark not just some
there should be stuff to charge up things and others to tell it when to fire the plugs
