Re: Rough idle and takeoff 250 inline
Of course!
Jump right in the deep end of the pool. Go right to 12. What’s your idle vacuum? Last edited by geezer#99; 10-04-2024 at 10:12 PM. |

Re: Rough idle and takeoff 250 inline
The only danger in advsncing the timing is going to far & causing detonation. As Geezer#99 said go to 12 & test drive it while listening for detonation on acceleration. If you experience no detonation then your good. Then enjoy the increase in power and trouble free driving.
