Just found ya'll today...great site. We have just acquired an '82 K5 for our deer camp. It's been sitting for a few years, I spent this weekend cleaning, flushing, lubing, etc, etc..everything I could. Even replaced EVERY single vacuum line on top of the motor. It runs but not well. The block and innards were replaced with new GM about 5K miles ago, the original carb, etc were put back on. When I got it to run it was almost WFO. I sprayed the carb real good but I think it is really gunked up inside and full of debris, changed the fuel filter too. The fuel line flushed out some debris into a bucket so I know it's dirty. Is there a favorite method for siphoning a Blazer's gas tank out?...the gas is vinegar, smells like crap. I couldn't get small tube to pass all the way through the filler neck....anti-siphon device? Also, I removed the Roch. Q-jet, sealed the motor, and brought the carb home with me(the truck is 300 miles away). Is there a recommended Q-jet rebuild kit that ya'll like? I think it will run like brand new if I overhaul the carb. Sorry for any redundant newbie questions...I'm on some Land Cruiser forums that are very similar to this. Thanks for any & all suggestions!!
