Fuel leak 69 Tripower
Hi All.
I have a fuel leak from the carby area into the valley but i can't see it when the engine is running and at operating temp.
Some background, last weekend I trailered the car to get a wheel alignment. The car was dificult to start but could have been me tickling the gas pedal a bit much. It finally started and was idleing well and went on the trailer fine. When i got to the workshop the car ran out of fuel (my bad) and the tech put some of his gas in the car, basic gas 91 RON i think. He squirted some starter fluid down the centre carb and it started and drove ok while i put it on the wheel aligner hoist.
Once it was completed i drove it out of the workshop, took it down the road to check the steering wheel alignment and put it back on the trailer. It was when i had parked it on the trailer I noticed a strong fuel smell but thought it was maybe the carb playing up a bit as the car has sat in the garage for some years and this was the first drive. Once i got it back home i noticed the smell again so I drove it up the driveway and into the garage. My wife said she could see petrol coming from the front of the car and on the driveway while i was turning into the garage. My driveway is steep and a right turn at the top to park in the garage.
I checked the the engine and noticed the valley low points where all full of gas but i couldn't see where it was coming from. I cleaned it down and got back to it a couple of days later. It started ok and idled well with the chock on, but no visable leak. the engine started to idle slower once the choke came off so i gave it a slow rev and it evened out. I then checked the idle mixture and the drivers side (still left hand drive) didn't faulter like it had on previous adjustments, screwed it all the way in and nothing. The passengers side did reduce in revs and almost stalled, so i adjusted to the correct position. Still no leak visable. I don't think its anything but the guy left the fuel cap loose when he put the gas in.
Then, I went out to the garage again today to check and there was fuel on the passengers side valley (please see pics), i have no idea where its coming from. The only thing i can see is its wet above the base plate.
I'm sorry for the diatribe but wanted to mention eveything that happened just in case something jumps out to those smarter than me. I'm thinking I need to strip down the carbs and clean everything. There has been no backfiring or running rough up until the W/A. I had just finished tuning the carbs and timing in line with Lars's papers and it was running well. One more thing, while the car was off the road i had the tank chemically cleaned and replaced the sender.
Any help would be very much appreciated as I now want to go for along drive and enjoy my car.
Cheers
