Hi, I bought a 1979 K5 Blazer (see pic), which is in great general shape, and is working on LPG, but... it starts great and goes strong on L and 1st, but once you shift into 2nd and 3rd, the engine will simply dismay, unless you are going downhill... Another issue is that I was given a door key, but it does not work... other than that, I'm inlove with "The Thing" and willing to have him fixed. Any ideas?... I have already tried regulating LPG pass, which improved only a little, but now mileage has decreased... My next guess would be clutch...
