I just got my new member of the family this past friday - 67 M715 and I've been tinkering with it ever since. The truck starts right up and idles great, but when I put a load on it I get maybe 50ft down the road and it starts to stumble and stall. I have noticed the fuel filter has junk in it , so my guess is the engine is picking up stuff from within the tank. Has anyone drop the the tank in there truck? and how forgiving are the tank straps? I also noticed there is no spacer plate between the carb and the intake, anybody have an idea why? The only mods that were put on the truck before I bought was a 12V conversion and an electric fuel pump. Any feedback would be appreciated.
