I’m an electrician not a mechanic. Further, I know very little about combustion engines and how to work on them. I can, and do, some work on my vehicles but it’s ancillary to the engine itself. Brakes, oil change, belt change, alternators, vacuum pumps… stuff like that. Remove the old, replace with the new type stuff.
Now I did have a good friend (RIP Phil) that was always giving me tips and saying, “You can do that yourself.” His most sage advice to me regarding combustion engines was they need three basic things to run. Spark, fuel and air. He said whenever trying to diagnose a “non running” or “running rough” issue to determine which of those three is the problem.
So this year my VW bus was running really rough. I barely got it out of the back garage and to the driveway where I had more room to work. Just had an engine rebuild a couple years ago and it’s been running great up until this year.
I initially suspected rodents and wiring. Didn’t find any evidence or damage. After getting it running in the driveway (still rough and stalling) I revved it up a little and it would backfire. I had changed the air filter prior.
By my thinking this said it was getting fuel. I was pretty sure air wasn’t the problem and so it must be spark. I thought it might even be a timing issue and had almost decided to mess with that and all of the sudden it started running perfect. I had just changed the spark plugs and wires, distributor cap and the armature (not sure if that’s the term mechanics use). The gods seemed to be trying to tell me not to mess with the timing.
I had already checked the gap on my points and didn’t think it was that, but ordered a new set of points and a condenser.
Today having finally had the time I was going to change those out. I decided I would just change the condenser and see how it ran before changing the points.
It was the condenser! She’s back up and running!
Total parts were about $75 so I didn’t have the bills you guys had but it did eat up a few of my weekends to get it back to running smooth.
I also get to silently gloat because my wife told me not to mess with it because I didn’t know what I was doing and would likely cause more problems.
