Well, it's not really the Hardy boys...sorry...just me.
Since I purchased my TR4, I've always felt it was a little lacking in performance. When starting out in first gear, I would let out the clutch, give it a little gas and then it would seem to load up, or bog down a little. Once I accelerated, it was fine. Not particularly quick, but decent acceleration.
I had never really driven the car much, so the other day I set out to the auto parts store in it. It was a very warm day and on the way there, it not only started bogging down, but it wouldn't idle and started dieing at red lights and stop signs.
After spending about 15 minutes in the store, I came back out and it wouldn't start.
Eventually, I got it started and it drove fine on the way home. I knew the timing was good, it had new plugs, wires and new Pertronix distributor, so I looked to the Stromberg's.
I went out to the garage with my laptop and found a few sites with exploded views of the carb. I took the top end of one apart and noticed a part not shown in any of the diagrams. It was a thin washer that was placed on the floor of the air valve piston resting at the bottom of the spring. When I removed it, I noticed it was blocking the air holes drilled in the base of the piston. I knew the holes were there for a reason, so I removed the washers from both carbs.
Now, not only does it start more easily, no choking required, but the car runs much, much better. It's much quicker and it doesn't bog down or die on me anymore.
What are these mystery washers for and why were they in the carbs?
