The other day i drove my car for the first time, properly, and did a six or so mile loop just about.
The car started popping and losing power momentarily and i just made it back onto the driveway. It was fine when cold but when it got hot the above started. This morning i turned the key and it fired up straight away so i pulled it out of the garage for a check over. I took the plugs out, they were slightly sooty and gaps are at 0.60mm on ngk bp6es iirc. When it was back together the bloody thing would not start at all. Lost my cool, nearly, and pushed it back in the garage. Tonight i tested the coil and there is a good blue spark on the test plug. so i'm thinking the coil and electric ignition module in the distributor are fine. My fuel pump is up under the tank and that is running no problems. My next check is to see if fuel is getting to the carbs, i find it odd that despite the pump running and plenty of fuel the plugs were not flooded or even wet in any cylinder. My first thought when it limped home was fuel evaporation but i'm not so sure now. More checks to follow (IMG:style_emoticons/default/headbang.gif) |

I recently had a similar issue I’ll share.
Lost my 3 port pump, so had it replaced as I didn’t have time to do it. Got the car home (about 2 miles), and in the garage. Went to go drive it and it run for a few seconds before it sputtered to a stop. Tried to restart waiting a few seconds and a quick pump to the throttle. Fired up and sputtered to a stop again. I could hear the pump run and stop once pressurized. So thinking fuel was not an issue checked the intake, spark, MPS, and CHT. All looked good. Gave up and towed it to Allen down at A&P in Portland. Turned out to be a easy fix. Turned out that the fuel line under the tank was too long and had gotten pinched. Not completely, but enough it wouldn’t keep up. Basics Air Fuel Spark It’s usually fuel related in one form or another. That’s why many went to carbs. Check the lines, filters, and if there was crud that washed though it could be jets. And yes carbs help here. |
