M35 Questions
How time flies....
This site has taught me a lot in the past year. This thread was started when I stumbled across my first multifuel. After quite a bit of hand wringing, I decided to purchase this truck.
I had always wanted to resolve this thread, but kept forgetting. Now seems like as good a time as any.
When I bought my '67 deuce, "C" turbo, it would barely get into second gear (not enough power). I managed to get into third once, going downhill. So, I did the basics. Read the manuals, searched and read all I could find on this site, and chatted on the chat rooms on occasion.
Changed all three fuel filters, took the in-tank pump assembly out of the tank to check the condition of the intake screen, and carefully went over the entire length of fuel line from the tank to the IP. A new air filter was installed as well. After all of this, it was still the same. Well, I did notice a small improvement, but it would not get above 20mph.
So, I purchased a pyro, researched all about them right here on SS, and decided to mount it pre-turbo. Removed the turbo (literally a 10 minute ordeal), drilled and tapped two holes in the manifold (one on either side of the divider) and plugged one.
I then cut the safety wires through the bolts retaining the cover over the fuel adjustment screw, and removed the cover. AH.... now I found it! The fuel rate adjustment screw has two nuts (jamb nut arrangement), both of which were loose! The nuts must have slowly backed off over time to the point it was when I purchased it. (The previous owner believed it needed a new IP)
I then gradually (read: 1/4 turn at a time) adjusted the fuel rate and drove the truck. It took 2-1/4 full turns of the nuts to get where I am now. It will run at 700*-800* on a flat run, while seeing 1050* on a long run up a big hill. It has never gone over 1050*.
David, I could not stand the bright green paint that the previous owner brushed on, so I bought some spray cans and a six pack of beer. While it is not very good to look at, it is an improvement.
I drive this truck every day, and couldn't be happier with it. A BIG "Thank-You" to all of the SS members who helped me through some really simple questions, that were anything but simple to me at the time. We all had to start somewhere.
This site is the greatest thing to happen to the late model Deuce (M35) aspect of the MV hobby.
