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? |

Stupid question, but have you pulled the valve covers and inspected that bank yet?
Go ahead and do the compression test - we need quantitative data to give you more advice at this point. As said, it doesn't need to be warm. Ideally, to get a fuller picture of the health of an engine, we'd like to do it with the engine warm. In this case, it's a "go/no go" test, so cold will be just fine. |

The answer is "no" unless you ask... Group: Members Posts: 1,184 Joined: 21-November 15 From: White Plains New York Member No.: 19,387 Region Association: North East States |
