your car doesn't have an alda try a good diesel purge and then see where your at.

Don't loosen the valves, adjust them correctly.
The only speed improvement options are 1- Get into proper tune 2- Sell it and buy a turbo 300D. |

My 78 NA 300D improved with Marvel Mystery Oil in the fuel in a couple of tanks(8oz per 20gal). Readjusting valves will be next. Also I found there was a sweet spot in the throttle between 1/2 and full that got the best acceleration without over revving the engine.

a little power service wouldn't hurt either. Don't use more than recommended as it doesn't improve things much after you go past that mark.
