hidden_hunter Posted October 9, 2014 Share Posted October 9, 2014 The pickup seems fine at low speed in the first two gears in our '26 standard six but above 15mph in third gear there doesn't really seem to be any real power at all (I know obviously they're not fast cars but I'd expect something). I've checked that the brakes aren't dragging Is there anything obvious I should be checking or adjustments? Link to comment Share on other sites More sharing options...
Leif Holmberg Posted October 10, 2014 Share Posted October 10, 2014 A friend of mine had the same problem and that was the spark plug cover.The wires wasn`t insulated good enoug.Or to long spark plugs if they are covered with the cover plate.And be sure to clean the dist cap inside.Leif in Sweden.

I'm guessing that's why there are so many cars that seem to be missing the the cover.. My distributor (both the unit and the cap) is fairly worn (I'm always looking out for a 26 disto and/or rotor to come up) so that might not be helping the performance. It's not in terrible condition but is showing its ageThe car is all original mechanically, so still running the original vacuum tank and marvel carb - it just doesn't seem to have as much oomph as it should Link to comment Share on other sites More sharing options...
Leif Holmberg Posted October 10, 2014 Share Posted October 10, 2014 Why not try to find a newer dist cap and rotor that will fit on your Buick.I have changed those parts on my 4 cyl.Buicks 1923-1924 and used VW parts on one of them and Volvo parts on the other.Leif in Sweden.

Mark Shaw Posted October 10, 2014 Share Posted October 10, 2014 I suggest you first check to see if the timing is retarded. Try advancing the distributor a bit. Link to comment Share on other sites More sharing options...
