If you are certain it is getting adequate fuel, then it must be an ignition problem or a timing chain issue, if one is present.

I'd look carefully at accessible wiring and try substituting another coil.

Bypassing the ignition switch and related wiring can elimninate some possible causes.

Points can be inpected for oiliness, improper spacing, broken springs, or evident corrosion.

The best test for a condenser is substituting a known good one.


Sometimes mechanical wear will reduce point gaps to the point that the engine won't run.

Condensers fail by drying out or shorting.


A failing condenser can cause damage to points by allowing excess arcing.


Some distributors have internal wiring that can suffer insulation failure.


Be sure you have a fully charged battery when doing any ignition work.


Some engines have the spark plug wires gathered into a metal loom. High tension wires can short or cross-fire and cause trouble even if they look new.

Plug fouling isn't likely to stop an engine, but I'd at least check a couple of the plugs for proper gap, gneral condition, and cleanliness.


Stale fuel can cause a lot of problems. Be sure you have plenty of fresh fuel in the vehicle.
