timing for propane
i have a 1994 f250 351w c6 auto on straight propane. i need to get it though an emissions test so i want to check the timing.
my question is where is the timing supposed to be on this setup .
i am also assuming that this engine uses a spout connector and that it should be disconnected in order to check and set timing.
any propane guys out there .
p.s. my keyboard cannot produce question marks or hyphens, so i am not as dumb as i appear in text .

Depends, If the dist was recurved approx 6deg over gasoline intial. If not or it is not limited in some way no more than 3 or 4
The problem is total advance. Most LP engines run best at 28-32 degrees total advance.
Good Luck

How to recurve the computer for timing. I have a F 700 that was factory propane truck
I have a 97F 700 with the 429 Ford engine in it it was an LPG truck from factory so I’m trying to figure out the timing and whether it was speed up or slow down and how I would go about re-curving it?
