tach on gp
i got the tach hooked up but it has 3 different settings.
01 is plug fires twice per revolution
02 is plug fires once per revolution
03 is ever other revolution
what should it be on?
i had it on 02 but it seems like the rpms were way high when idleing....

Set your idle on the trailer at 3000 will come down to about 1300 in the water.

so setting the tach to once per revolution is good? There is no funky ignition?

Fires once per revolution
What does it read in the water and what does it read on the trailer
