Subject: Re: Few repairs and upgrades to the 79 by rklessdriver on 2011/8/16 21:45:11 It never ends with this f'n car..... Sunday we took the car on a 30 mile drive to dinner. I watch the temp gauge like a hawk and after a while of normall driving I noticed the temp was still barley above the 160*F mark. I punch it, lay into the 4 barrel a few times to see how the temp does..... stays rock steady at 160*F, however I noticed it was really noisey under the hood at RPM. I pull over and stop the engine. I grab on to the fan and yep the fan clutch has failed in the locked up position. No worries there, at least it's running cool. Once we got back I put a timing light on it. Car just seems to lay down really bad for about a second before it shifts at WOT. Seems it only had about 5* of total timing (off the scale in the negitive at idle).... Not sure what it should be at idle I use an old racer trick and pull it up to 36* total, make sure it don't buck the starter (everything is good and it starts right away). I then go to adjust the carb to idle it down and find the idle screw is bottomed out.... damn thing won't idle below 1800RPM.... I get out the brake cleaner and start checking for vaccum leaks and I find a big one on the drivers side front of the carb base plate..... Closer inspection reveals that some moron (when they removed the idle mixture screw block plugs) busted off a huge chunk out of the carb base plate.... Sorry guys but it looks like a new carb is in order before I even think about an elect fan conversion. Will |
