Nice story Nick: I have one as well. Last year I decided to put my Invacar (not AC) Model 70 in the local parade during our Gladiolus Festival. I even washed it and made it look pretty. I had a hard time starting it that morning, the time was about 10:00 am and the parade didn't start until 5:00, so I had plenty of time. Sometimes if it doesn't start first attempt, it takes forever. Finally I was successfull in starting it, and once it starts, then it is normally good for the rest of the day. I took it for a run to the south-side of town ( a mile away) and it ran nice, but couldn't make over 20mph. Since I didn't have time to see why, for I had many other cars to get ready as well, and the parade only goes 1 or 2 mph anyway. Well as it happened after lunch everything was in order so I decided to take a look at the Model 70. Still couldn't pass 20. I took it back to my shop, and thought that I'de change the plug wires. Being only two, not difficult at all. I put new wires on and cleaned the plugs, they were not dirty, but cleaned them anyway. It started right up, put in forward, twisted the throttle and accelerated. Boy did it take off!! The front wheel I am sure was six inches off the ground and in about 200 yards doing 50mph. Exhillerating, especially since the handlebars are really stiff to turn, so I put pressure on the bar to brake and it did so wonderfully and in a perfectly straight line, and the open windows even closed all by themselves, sliding forward. Ran beautifully throughout the parade, with even photos in the local newspaper. Great little car. Ian.
