turning up pump does it help starting

[6x6junkie]

hey guy gals when you turn up the pump will it help with starting the mulitifuel deuce

Yes, but "poor" fuel is not the problem and turning it up is little cure if yours is a bad starting engine. Even cold it should come to life after just a few turns cranking. Check for operative lift pump, correct timing and also condition of starter and batteries.

.... turning it (fuel) up is little cure if yours is a bad starting engine. Even cold it should come to life after just a few turns cranking.

I have to disagree. If the fuel is turned too low it will affect starting. My truck was always a good runner, a little underpowered, and often hard to start. I cranked up the fuel 1/3 turn (two flats of the adjusting nut) and it was like a new truck. More power and started in a flash. Eventually I installed a pyro and found my EGTs were still well below recommended max. My fuel rate must have been turned way down to start with.

i don't see how it could, the pump goes to full fuel when not turning so that starting gets max amount. there are many factors in play like injectors, ip head worn, timing, cranking speed which is very important, fuel supply not leaking down, etc.

An in shape deuce is known for being a FAST and dependable starter, If its slow there is a need for PM. ...Randy

15 years ago that was my case too, with my first (Toele) rebuilt LDS 427-2 Multifuel powering an old M35. When cold it always took relatively long, fast cranking (over 5 seconds) to start firing. At that time I didn't know much about those engines, even thought it was normal for them...!
One day I decided to "play" a little bit with the timing, to try different settings, just little by little at a time. Can't tell exactly what and how many degrees it was but from the very next day on that MF was a pleasure to start, literally jumping to life. It has been that way ever since! And I would say that THAT is normal for our Multifuels!

We bought a 5 ton tractor that would not start and idle right. We turned up the fuel and the problem went away.
