1968 C30 DumpTruck Engine Probs! Help!
Hi, its Chevytruckjerry again, after a little hiatus. I had to sell my project '68 C10 earlier this year, so I hadnt been on in a while. Now, I have a new project, a 1968 C30 DumpTruck.
Call me certified crazy, but I'm going to make this my daily driver for a while. I do 18 miles a day total to work and back. Its just one of those things where I havent finished a project or anything cool in a long time and I want something "different" to drive to work everyday. lol Anyway, it belongs to the boss of a friend of mine, they used it for hauling garbage (works at a cemetary). They told me it ran great, then all of a sudden one day started running like crap and backfiring, pretty soon it wouldnt' run long enough to move it. So the boss is getting rid of it. I just need to get it running and get it the hell out of there! It has the 250 inline 6, coupled to a 4 speed (not sure which one, im hopin a muncie 465). It has a Rochester MonoJet, looks like the same carb that should have been offered on that year truck and engine, but has a remanufactured tag on it dated sometime in 2001 so its probably not THE original. So far when I tried it, it would only run with the choke all the way out, even when it had been idling for a while. Needed to give it touches of the throttle to keep it running, too, and it ran like crap. They said it backfired, so I would have thought they meant out the carb, but every now and then it exploded out the tailpipe, so I was figuring not all the fuel was getting burned. That day I tried it, it just seemed to get worse and worse. Pretty soon it was all I could do to get it started to run for just a few seconds. The points were pretty worn, so I changed the points, condenser and coil. I also loosened the distrubutor and moved it arounnd while cranking. Tried it, and it was worse. This time it would crank and crank with only a Huff every now and then. I checked for spark, im getting spark. Checked for fuel supply, fuel pump supplies plenty of fuel. Moved the throttle lever and you can see fuel squirts in there. So i pulled the carb thinking i need to rebuild it, when I did that i noticed the bottom of the intake passage right under the carb has a puddle of gas in it. Can the carb be so gunked up its not atomizing the fuel correctly. I ordered a carb kit already. What do you guys think? I appreciate any input, and cant wait to get pictures of my baby on here soon. Thanks, Jerry. |
