Advance ignition timing on CS-590
Made in USA
Not for use on CS-620
        GENUINE GEARHEAD PART--ALL OTHER SELLERS ARE COUNTERFEIT.  TRAVERSE CREEK INC IS THE ONLY AUTHORIZED DEALER FOR THE GEARHEAD BRAND OF PARTS.
    • GET THE IGNITION TIMING ADVANCE THAT THE 620 COIL OFFERS
    • NOT FOR USE WITH CS-620 COIL
    • Get the performance of the popular CS-620 coil upgrade without the expense. This offset key gives the saw an additional 6 degrees of timing advance. With the factory 590 coil, this mod gives the saw very similar timing numbers to the 620 coil in the actual powerband of the saw.  This does not eliminate the rev limiter of the 590 coil but this normally isn’t a problem since rpms will normally be 12000 or less in the cut (rev limit is 13500 rpms).
