Mr. Cummins and the person that invented the Weedeater share a since of humor. The Weed eater or string trimmer is a labor saving device that can have dyer consequences. Especially if you own a dog that likes to leave you a present in the tall grass next to the fence. Mr. Cummins or more correctly the engineer that designed how to mount the VE fuel injector pump shares the same sadistic humor. It took me almost two hours to change the timing on my truck the first time. It would have taken days if it weren't for the wonderfully nice and helpful participants in this forum. I looked at the mounting bolts and really thought there is no way in God's green earth that anyone could put a wrench on them, let alone turn them. Monty's pictures and others advice plus the generous application of a torch to a couple of old wrenches led me through. I will admit that the second adjustment took all of ten minutes and the third less than that. After the first adjustment I of course went for road test. I had a lot less power than before but no knock. I had only moved the pump about 1/8th inch from the original setting which, was 3/16 past the factory mark. I went back to the original setting and still no power. I will admit the use of a small brass hammer to motivate the initial adjustment along with the constant pressure of a web ratchet strap. I figured that I did something terribly wrong to the throttle position sensor or somehow damaged the Fuel pin or the diaphram. Upon disassembly I noticed the throttle wasn't looking exactly right and lo and behold there was a fuel line stopping its total travel. I bent the offending line out of the way and I returned the timing back to the advanced position and cranked down a quarter turn on the spring adjusment under the diaphram and threw away the shims. The truck almost scares me now! Basically it looks as if the engine has not ever been to full throttle since I have owned it. That is why the transmission seemed to not want to go into overdrive unless I lifted and let it shift. Someone prior to the last three owners had a reman fuel inj. pump installed and I think that could have been the reason for the fuel line interference. With the installation of the 3200 gov. spring, which should be here Wed. I will be looking for some of those Rice Rockets to smoke off. Guess I will have to find more efficient turbo next. Does it ever end? Can't wait to get with some more of the VA chapter seven so I can spend more money and tweak this thing in.

 

I was just going to put a 12 cm turbine housing on and turn up the pump a little. You're DOOOOMED!

 

Did I say that? I didn't do it, no body saw me, ya can't prove nutten.
