Can anyone say, "HOLY CRAP!!"

Well, I decided that I was gonna check the plugs on my truck as it was still running really rough on me. So I popped the hood and started pulling out the plugs, one by one, with three being clean, and not carbon coated like the rest, with all of them being totally coated in greace. While I had all the plugs out I decided to clean off the plug cables which were all black with greace, I was surprised to find out they are actually a very light grey, looks good actually... I happened to stumble across a compression meter, and hooked it up, the compressions were as follows:

Cylinder 1 - 120
Cylinder 2 - 120
Cylinder 3 - 119
Cylinder 4 - 121
Cylinder 5 - 135
Cylinder 6 - 120
Cylinder 7 - 136
Cylinder 8 - 120

My dad's old Chrysler Fury had 35 on it's best cylinder, lol! Both my father and myself were simply amazed at the compression that those cylinders had, So I finished cleaning off the cables, plugs and cable locks, put it all back together and tried to fire it up, battery was dead (I really gotta replace that, I've never been on the road with it, and this is the 4th time its died on me...) so we hooked up the charger and I decided to take a look at the distributer while I was at it, simply beautiful, no signs of wear at all, apparantly the engine in my truck had been replaced less than 50 000 km ago, so it must have been replaced at the same time. So the battery was charged enough to turn the motor over, only needs to turn once or twice to start, so I turned it, and the motor sputtered to life, then died. So I started it again and gave it some gas, just to see a big cloud of smoke come out from undernieth my truck, super flooded engine, then it died again... So I got it started a final time and started running it at a very fast idle to burn off the extra fuel from the compression test. The truck ran for about thirty seconds, then started coughing and died. Well, what the heck. I took it apart and started fiddling with the carb, no fuel was being sprayed in! I figured that I musta ran outta gas. So I grabbed a jerry can and poured it into the tank, then turned the engine over once or twice, still nothing... we played with the carb a bunch to try to figure out what was going on with the machine, it was getting gas but an hour ago, and I hadn't touched the fuel system... So we pulled off the fuel input to the carb and turned the engine over to see if any was gonna sqirt out, maybe we messed the carb up or something, no gas came out... Now we were scratching our heads, that truck has a brand new fuel pump on it... My father turns to me, and asks if I put the gas in the right tank, only one of the tanks was hooked up, as the fuel switch died a while back. So I got underneith and started following fuel lines, doh. I put the fuel in the wrong tank, lol, my father laughed at me till I told him how much gas I put in that tank, lol we then shrugged, poured a good 30 litres into the right tank (I put about 10 into the other one) then turned the engine, gas instantly starts flying out of the hose, we put it all back together and start it, it starts! Still running rough though, and clouds of smoke are still coming out the rear... So I keep it at a fast idle to make sure that it didn't stall again, and suddenly the truck starts sounding better, then better! The dead cylinders were firing! Five minutes later the truck is sitting there idling at a very fast pace, only missing a beat every couple of seconds... So we open the hood to adjust the carb to slow down the idle a bit, and after doing so I notice that one of the plug cables had been knocked off, we put it back on and started the truck again, it just rumbled smoothly, so we adjusted the carb again to get the idle right, then took it for a run up and down the driveway...

Now this is the holy crap part - Before I had to pretty much floor it for the truck to start moving at any somewhat decent pace, our V6 Blazer could easily outrun it, now I barely tapped the pedal to give it some gas and it just took off like no ones buisness! I figured ok, that was amazing, lets see what happens when you floor it... I dropped the pedal and was amazed as the tires started a spinnin' like no ones business, I quickly brought the truck back home, grinning from ear to ear, I put the truck in neutral and decided to see what it sounded like in a rev now, before it sounded impressive enough, but it just didn't have the power, so I gave it a healthy dose of gas and literally giggled with glee as the truck just roared, as the exhaust screamed out of the back, clean exhaust, no more black smoke! Lemme tell you, a 1/4 of a pedal of gas sounds one heck of a lot better than it did floored before, Dropped to the floor, the truck is able to bring on giggles of glee from a 16 year old guy and a 40 year old man, lol

Tuneups rock!!



And such ends my story of embarassment, work, and pure glee
