Odd starting problem UPDATE - FIXED
Within the last week my 84 Cj7 (258, MC 2100, TFI ignition) has started to act up when attempting to start. Now it is a daily occurance and is predictable.
When I go to start it, the starter spins, and everthing 'sounds' like it is going to catch. I see gas pumping down into the carb when I activate the throttle. But it does not catch. I find that when I hold the gas pedal to the floor after a bit of pumping, about the fourth or fifth try it will start. A bit of white smoke out the tailpipe and then everything runs perfect. Once running it idles clean, runs strong, etc. I tuned it up about two months ago in prep for emissions, plugs, cap, rotor (TFI stuff), cleaned the K&N filter, verified timing and vacuum. So I am confused. It does not seem electrical in that I can hear the starter spin. I see gas, it gets air (it does the same thing with the air cleaner off). I can recreate the situation at will. Shut down the engine, wait a couple of minutes and then again I will have to mash the accerator to the floor, crank four or five times, and then bingo it starts. It does it morning, noon, and night, not a temp issue I presume. So what am I missing here? I don't think it is bad fuel. I am trying to get to the basics (air+fuel+spark = start).
All advice, comments, questions, and witty insults appreciated.
