Hi All. I was working towards getting on the road formally this spring and seem to have caused a problem while digging around the engine bay.
It's a 74 1.8 with a single Weber progressive and an 009 distributor (I know nobody likes that setup ...) and Pertronix Ignitor. We have had it running (adjusted valves and timed it) and even put a few miles on it over the last few weeks. Today, out of interest and while trying to find out my Pertronix model number, I took the cap off the dizzy, pulled the rotor and magnetic sleeve and took out the Pertronix. There was no part number (ugh). I put it all back together (it has been running, albeit not well). When starting, I got a bright flash above the engine (!) and the car tried to run but it will not idle and backfires like crazy. So much so that I am not comfortable trying to start it again. (IMG:style_emoticons/default/confused24.gif) I did check all the wires and plugs and all seems OK. I think the Pertronix is still working (it does fire). Could removing and replacing that part mess with timing or hurt the unit itself? I cannot see why but it is running like the timing is waaayyyy off. Does anyone here have any ideas on what I might have done to cause it to not run well. How about ideas of what I might do to get back on track? My only thought is to go back to points, static time it to start and go from there ... I really appreciate the help! |

So it took a while but I finally figured out that two things had happed to cause the non-starting.
1) did not tighten the distributor after timing so it turned itself out 2) when fiddling with the Pertronix, one of the magnets from the "doughnut" on the dizzy shaft popped out (the piece separated). So found the missing magnet and got that squared away and re-timed and things sound pretty good. FYI the Pertonix is a Ignitor I (1?). The config for the 009 distributor has a fixed sensor so no adjustments possible or necessary. Thanks for the help on this. |
