I have suffered a recent loss of power, which given the meager amount to begin with, is catastrophic. Ok. I’m over stating it a bit. (Background info: I work at an altitude of 4500 ft, but I live at 6000 ft) Going up my mountain highway after work, I could previously hold 4th gear to a particular sign next to the highway. Now I have to downshift quite a bit earlier. On steeper parts in 3rd gear I could normally hold to 3500 rpm the entire way. Now it bogs down to <3000 rpm in some of the steeper areas.
I installed a new electrical fuel pump which eliminated the vapor lock issues I had over the summer. I installed a new carb kit. I am getting horrendously terrible gas mileage. The plugs always look just slightly rich. New spark plugs/wires/distributor cap/rotor/points. Here is my full British car tune up procedure (sort of like a full Scottish breakfast…without the blood pudding). Please let me know what I am missing.
1. Re-torque cylinder head bolts
2. Adjust valves
3. IRAN (inspect and replace as necessary) plugs, clean, re-gap and reinstall.
4. IRAN distributor cap, points, rotor, condenser
5. Set point gap, start truck and warm to normal running temperature, measure dwell angle, readjust points as necessary
6. Set up timing light. Remove vacuum advance line at carb. Check timing holding thumb over vacuum fitting on carb. Adjust at distributor to spec
7. With tach/dwell meter still attached, adjust idle to 1000rpm (Weber 34ICH). Adjust mixture for best running.
8. Recheck dwell angle and timing.
9. Button it up, test drive and note that I have still lost power.
Other ideas?
