This is a continuation from another thread, but to summarize my car very suddenly started driving like crap yesterday. In the middle of a drive it started popping and sputtering, and became pretty much undriveable. AFR was suddenly in the high teens.
At first I thought it was to do with fuel delivery. That turned out not to be the case. What I noticed today after I managed to get it to actually idle is that during warm up, cylinders 1 and 2 seem to be acting normal. But 3 and 4 heat up extremely quickly, and heat up past their normal idle temps and would probably continue to heat up well into the danger zone if I let them. I'm running DRLA 40's, and I'm still getting to know these carbs. The idle jets are clean. All I can think is that there's possibly a vacuum leak, maybe a seal or gasket failed suddenly while I was driving. They were rebuilt about 5 years ago though. Time for a rebuild? Anyone who knows Dells well know of anything I should check before I start tearing them apart? And does the rebuild kit from CB include everything I'll need? |

Leave the 'paper' on the phenolic spacer. If the intake to carb gaskets have been on and off a few times replace them. Tighten the carbs down like wheel lugs. Go around a couple of times snugging them up gradually and don't over tighten them avoiding building in a leak. The Venturi in ? might read vastly dif when comparing it to the others with your synchro tool. The CB manual is your friend.
