Car had been acting wierd since the last fillup, especially when starting from a dead stop. Unfortunately, I put 89 grade ethanol in it, without reading the pump. (Best grade they had.) I figured that the problem might be minor vaporlock or just poor performance from the crap gas.
Well, on the way to work, the car was acting worse. Several times the car just stalled at an intersection, and I'd have to give it lots of gas to start. Starting was very hard. At lunch, the car wouldn't start. I noticed the outside of the right carb was dripping. Checked hoses, and tried to start again. Engine started to turn - then stopped abruptly. Let it set, and it finally started. I went to get gas and stop by BK for lunch. I filled it up to dilute the ethanol, which I still believed was most of the problem. In the drivethru, it stalled twice. I couldn't get it to start the second time, so I pushed my 914 through the BK drivethrough. How embarrassing. Well, I get it out of the way, and try to start it again. Same "locked" problem. Give it a few minutes, and the starter clicks once. Hmmm. Battery dead? Try to start one more time, and now the starter whirrs freely, like the gear was broken off the end. Here's my hypothesis/diagnosis: Right side carb has a needle valve stuck open. Would cause poor running problems at low RPMs. When the key is set in the run position, it starts to fill 1 or more cylinders with fuel. Starting the car, I had a partial hydrolock. I didn't ever try to push-start the car down a hill or anything. The resistance from the engine damaged the starter. Thoughts? Comments? Bets? -Rusty |

QUOTE(Lawrence @ Jun 5 2003, 03:16 PM) I pulled over for gas at a local station - most Midwest gas stations carry it. Anyways, there were two grades at the pump. 87 and 89. I didn't notice the 89 was a ethanol (10%) blend. -Rusty The 10% blend shouldn't hurt anything, unless they're pumping the bottom of the tank and it was full of water. That doesn't mean it can't be the gas because I've got some skanky stuff before myself. Our Sunoco 94 and Pioneer 93 octane are both 10% blends and I've never had a problem. Did your distributor get knocked some how? Did you tighten it last time? Also you could check you accelerator pump diaphragms, if they were the real old type the ethanol could have damaged them. Could be part of your leak. Hydrolocked? Did it rain? I don't know about the /6 webers but the 4 have a choke enrichment circuit that if the get accidentally opened can wash down the cylinder with fuel. Just some guesses. Good luck! |
