Question on Ignition Timing

Posted by SteveP516 On 2010/11/25 15:02:23

Hey Guys,
I need a little help regarding the ignition timing on my '40 110.

The manual describes "with the fuel compensator set at zero spark should occur in No. 1 as per the data...."

Can someone shed some light on the fuel compensator?
Is this the graduated scale on the side of the distributor?
Any help would be appreciated.
Thanks,
