This car runs on natural gas. From the moment it starts, it runs rough. Put your foot on the gas (any gear or neutral) and it gets worse. Put a meter on it and drove around and noticed that (trying to remember exactly) the timing at say 900 rpm's and moving at ten mph is something like 10-12-14 degrees, but step on the gas just a little and timing jumps 20-24-28 degrees and engine starts pinging bad. Now if you put the petal to the metal from here timing falls back to 10-12-14 degrees and she takes off like a rocket! But anytime and at any speed the throttle is just off idle through 2/3 open the timing is advanced ten to fifteen degrees higher than it should be (in my opinion) and it runs bad. Any ideas or comments?
have the same problem?
