Tune ups
How often (in miles) do you guys perform routine tune ups? And what all are you checking and adjusting? This being my first Model A, I sometimes feel there’s a need to be constantly tweaking on something even though the car is running really well.

I have a Model A that was last tuned up in 2001. I have replaced the spark plugs twice since than, but have not touched the timing. Car is driven around 200 miles per year. Enjoy. |

Re: Tune ups
Tough question.
It all depends. These old critters don't need too much. The points do need some attention when recently replaced. The rubbing block will wear a bit until it 'settles in' meaning the points will need adjusting for awhile. If the timing was set correctly when the points were replaced and set then just re-adjusting the points is all thats needed. Other than this these monsters are fairly bullet-proof. Oil changes every year or 1000 miles with a good detergent oil. I prefer a 15-40. Along with that is a fluid check and visual check of everything. Once in awhile the clutch and brakes may need an adjustment. |

Re: Tune ups
It's interesting how we tend to measure point gap right down to the nat's eyebrow, so to speak. Recently I was on a drive and my car just quit with no other symptoms of loss of power, except for just the last minute or two before dying where it sputtered a bit.
The problem wound up being the points. Stock style with the adjustable point contact within the point block. Stock-style but aftermarket. I had last timed the car about 9 months before and had driven quite a bit. I had the clamping screw tight so the point contact would not move (So I thought). Over that 9 month period and probably 400-500 miles later, the point contact had backed its way out of the point block to the extent that the gap widened and widened until there was no contact, thus no spark. Easy roadside fix. My point being that even though we set the points to be "dead-on" which will provide optimum operation and also allow for future wear, the Model A engine is very, very forgiving. Those engines just want to run on a wide variation of point gap. |

Re: Tune ups
Points...I have seen the modern style point plate units swapped out in just a jiffy roadside on our club tours over the years.

I use the cheapest TT10 plugs and they have done about 50,000 hard miles in my Tourer. I can still get the same economy figures out of it as I did when they were new and I cannot notice a decrease in power or anything else. IMO, in these engines a set of plugs is a lifetime proposition and as for tuning, I ask WHY?
