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? |

Pulled my plugs. 1, 3, and 4 looked good: tan-brownish. 2 was black and sooty.
#2 was also running more than 100 degrees cooler than the next coolest cylinder. I suspect it wasn't firing at all. Possible plug failure? That still doesn't explain why 3 and 4 went lean and are running hotter than normal. Possibly two seperate issues happened at the same time. I've got a 12mm adaptor for my compression tester on the way. I'll post compression results as soon as I know. |
