I had a few minutes of “oh no, what have I done” after I put it all back together because it didn’t want to start. I pulled the plugs again and poured in some oil, which didn’t have the immediate effect I thought it would have. I tried not to overheat the starter and just when I was about to give up it made the faintest of starting noises. I let it rest for a couple of minutes and gave it another go and it tried a little bit more, then finally stumbled back to life. And then came the smoke, OMG the smoke! It was so bad I had to jump in and drive it around to keep from suffocating.
I’m looking forward to seeing what, if any improvement this will make.
