New here. I just bought an 87 Mack R688st. First, I wanted to say thanks because I was able to fix a bunch of things on the truck just off of the information I found on this forum, so it's been invaluable.
Anyway, I have a 12 speed e6 350. (I'm a new driver)
Having a bit of an issue with the truck stalling, wondering if I should be doing something different.
I turn the truck on. Build up air. Push in the brakes. Push in the clutch shift the truck to 1st direct and then the truck stalls.
My question is:
Should I be revving the truck as I'm letting off the clutch to get into 1st gear?
Do I need to rev up a certain rpm?
I.e. shift into 1st at 1200 rpm?
