Re: timing ona 235
Distributor turns clockwise (same as firing order of plug wires), so turning it counter clockwise (against the rotation) advances timing.

Re: timing ona 235
To correctly time a 235.
loosen the vacuum advance bolt in the block and line up the dash stamped into the block with the 0 on the vacuum advance plate, tighten the bolt. Then loosen the vacuum advance clamp on the distributor disconnect the tube to the vacuum unit. Using a timing light bring the pointer to dead center of the BB. It is now properly timed. If you want to advance the timing loosen the block bolt and advance it there. No light needed. This is actually called an octane selector. |
