I'd go with the dist. cap. first. But Pat has point. You can
check the ign. wires<br>
buy using a spray bottle with water in it. Suggest doing it at
night when you can <br>
turn off the light (or maybe have a helper standby the light switch to
turn it off and <br>
on). With the lights are out, spray water all over the ign.
wires. If the insulation<br>
is breaking down, you should see sparks jumping around in the engine
<br>
compartment.<br><br>

Engine turned over fine, sounded normal, but it wouldn't start.

</font><font size=2>So I tried it today and it started right up. So

</font><font size=2>Any ideas on how to fix this? I'd hate to be
