What gap should points be set at?

What gap should points be set at?

The Haynes manual recommends a point gap of . 016-. 020 inches for engines used in the P1800.

What can I use to gap points?

Rewards can only be used toward purchases of merchandise made in-store or online at Old Navy, Gap, Gap Factory store, Banana Republic, Banana Republic Factory store, or Athleta in the U.S. (including Puerto Rico) and Canada.

What happens if ignition points are too close?

As they close, current from the ignition switch flows through the contacts into the coil’s primary windings and then off to ground. All that current flowing across the points doesn’t like to stop suddenly, and can initiate a small arc, which eventually erodes the tungsten contacts.

How do I know if my points are working?

Test for continuity between the block and the stationary point attached to the distributor plate. Rotate the engine until the points are closed. Use the multi-meter to test for a good connection between the points. A slight gap when the points are supposed to be closed will keep your machine from running.

What causes a VW engine to backfire?

An intake manifold leak can also make mixture so lean that it backfires, but then should also have a terrible idle. A bad condenser can also weaken the spark and cause backfire.

What happens if point gap is too big?

Too wide a point gap decreases the dwell angle. This does not give the coil sufficient time to charge, resulting in a weak spark. It also slightly retards the timing. In short, either too wide or narrow a point gap will cause a misfire under load.

Can a bad condenser cause weak spark?

Weak spark is often the result of a bad condenser (and it’s a cheap part to replace). If you see higher resistance here, then you need to clean and check the connections and the circuit path to ground through the points. Also check resistance between the distributor body and the engine block.
