    The Alro cover allows you to advance the timing up to 7 degrees and 3 degrees retard

    Ryan what kind of performance gains can I expect with that cover? I have and ESP piston ported 26, Proline reed and a WT-257 carb.

    General principle: retarding the timing allows for more top end, advancing the timing allows for better torque. This product is for the true 'fine-tuner'; modifying the timing a few degrees will give a moderate performance gain.

    Would I have to run a higher or lower octaine gas? I run 89 now.

    you should be fine with the 89. your only adjusting the firing timeing, not the compression.
