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 |

Lawrence,
The gear on the starter looks OK. If there are no other problems you should be able to use it again. A suggestion on your plans for a filter - avoid putting one on the suction side of the fuel pump. Pumps can create pressure well and force fuel through a filter element. Fuel pumps don't suck well and any obstruction, even water from the gas tank, can create enough resistance in the filter that the fuel pump can't overcome it. You're much more likely to starve the engine. At this point, starving the engine may be the least of your worries but the next time you're climbing the hills of Kansas you don't want to short your baby of gas.
