Please can you advise what timing screw adjustment most of you guys use after installing this unit, msd quote two turns out, would appreciate your recommendations and experience

Thanks in advance

 

i believe they come at zero timing from msd, you have to turn it to advance or retard. to verify timing on the msd though you need a timing pointer installed and set to a balancer with proper timing marks

 

It should be set at zero and timing adjusted by programming. MHO.

 

thanks guys, advice appreciated

 

yes i agree
