RE: Overfiring?

[renarac@domain.elided (Owen Minor - Egghead Software Tacoma)]

Well, how about a fuel supply problem. Have you replaced the fuel filter on the BOTTOM of the fuel pump. It might have the integral fuel filter. If you do, just unclip or unscrew the holding strap and look in that little bowl that's on the bottom of the fuel pump. If you have that style, the can is about 2.5" dia by 3" tall. Inside will be FRAM filter #G-3. Have you used a seperate gas can as a fuel tank to eliminate the possibility of a clogged fuel tank or fuel line?
Replace you coil? They're just common coils and should be no more than $12 at a parts house. Considering that they mount right on the engine, they don't lead an easy life.
Replaced your condenser? $2 max.
Did you get GP, BlueStreak,Philco, BorgWarner or original IH points? Some no-name brands are pretty flakey and could have cheezy springs.
Look in your distributor. Clean the contacts on the woven wire ground strap.
Check continuity and resistance on your ballast resistor? I don't know the spec. Anyone?
Could anyone you don't get along with have dropped a ping-pong ball in your gastank? Doing that will give these symptoms...(GRIN..I'd NEVER do that to someone...muahahaha!)

Honestly, check for fuel obstructions first.Especially since it's new to you and you don't know how often filters were changed and if the fuel tank was kept fairly full to avoid condensation in the tank.
