Is the Gv-1/Stator Gator the best combination to use on a gasser?

Gv1

The Gv1 is a good governor and you can use the std GV1 sensor,just mount the sensor so it picks up a strong pulse from the flywheel magnet.I use this method on both my gassers with good results.

The GV1 sensor "pointed" to the flywheelmagnet:
Works fine.

will it read the head speed that way or do you have to cut it back some so it doesn't over rev

Thanks fellows I appreciate your help. I'll be ordering my first gasser this coming week and after getting the engine broke in, I'd like to fit a governor.

Eric, Is your sensor right up against the engine case? Is the flywheel magnet easily seen or do you just move the sensor around until you get a good, strong reading and mount it there?

"will it read the head speed that way or do you have to cut it back some so it doesn't over rev"

The GV-1 will calculate the headspeed based on the engien rpm
and the gearing you program it to

Hi Larry,
It is not that critical. I do try to "look" for the correct hight to mount the sensor.
An little air gap between the sensor and engine case is needed otherwise the sensor will rattle to pieces
Common practise is to trengthen the sensor case with epoxy, and to support the electrical wire comming out of the sensor.

The sensor readings I get are between 80 and 90%, that's on all of my gassers.

Eric.

I am not trying to hijack the thread but I am having problems with my gv1. I have a 12FG set up with my spectra and gv-1 problem is on Idle 2 I have it set for 1780 and it's running 1905 I have calibrated the fg to the gv but it doesn't seem like it.

No worries Mike,
Have you selected rotor rpm and not engine rpm in the GV1 menu?
It can't hardly go wrong, select rotor rpm and the right gear ratio you're using.

Eric.

If programing the governor with the 12FG is anything like the 12z, I feel for you. Once I figured it out it wasn't too bad, but the manual really sucked with the description/direction.

when using a Stator Gator how do you know if it's working or not?

I dropped my rpm in my fg manual it seemed to work just sucks you can't dial it in with the correct numbers.

Very easy to tell if the stator gator is working properly,
Just start the motor, look at the gov. readout, if the rpm reading is there, its working.

If your using the Vario stator gator with the switch, same as above except if the wires are backward, the rpm readings will be extremly jumpy, like this
{900, 540, 0 , 860} all that is the space of about one or two seconds.

Best to just hold the blades, run up the idle to just past quarter for just a very brief 1/2 sec, watch the readout, if it looks good with the rmps run up and back down smoothly, the stator gator is working.

And if its a brand new motor, it is best to allways run a few tanks through without using any kind of govenor first. Just take the blades off and let it idle a few tanks if you want.

Which is worse, ignorance or apathy? I don't know and I don't care!
