Model A Bucking with Acceleration
- Thread starter TMB
- Start date
JayJay - That is correct. I had no issues with bucking before this head gasket replacement project. Bucking improved once I used Les Andrews timing method so it implicates the distributor set up someplace.
Rotor does not wiggle and gaps all 0.025 with feeler gauge. Famous black wire is modern and in good shape with all insulators intact. I did not recheck the point gap on the replacement set so will recheck.
The prior set of points were misaligned as you can see in the photos. The point arm rubbed a groove in the block (red arrow) and was sticking open when I initially tried to start the car after successfully replacing the head gasket. These points were working before the project and the car was running fine. Replacement set are now aligned and not scraping the point block. Now waiting on a new set of original points and condensor to be safe and restart the timing sequence again.

My 30 coupe that I bought about 1962 had all original Ford parts in the distributor. I drove that coupe all over California. The same parts were installed in 1967 when I sold the car. I never had to mess with the distributor or change out the points or condensor. Good quality stuff.
Update 2025: I have had good luck with V8 points and condensors in my distributor. Although one condensor failed which fried the points. I have the updated upper plate with the rubbing brass connector to the bottom plate. I carry 3 spare sets of points and condensors. The points match up perfectly and the brand that I buy has a good quality rubbing block. The cam is polished and lubricated.

Re: Model A Bucking with Acceleration ( re-gapping POINTs several times infirst 500 )
1. My experience in the past 60 years is that in the past 15 years is that many repro point "rubbing blocks" wear VERY rapidly. that is in under 150 miles.
2. If someone asks you to check the point gap on a set of points which you replaced recently Do Not think that re-gapping is not needed (just because points are new!)
It is best to check the gap especially if they have less than 500 miles on them and you have NOT re-gapped them several times!
3. After re-gapping points for 2 or 3 times, the rubbing block will "work harden" and no longer require re-gapping.
4. After about 500 miles re-gapping 2 or 3 times, re-gapping will no longer be needed.
5. Polishing the distributor points cam and lubing with points lube (NOT Vasoline) will cut down the number of times that you must re-gap points!
