Weber - gas coming out of 1 throat

[SENC]

Excellent!

What a saga which I've only just come across, having serious problem with my wife's Xedos' ECU.

I guess your Weber supplier owes you a refund for faulty goods, it doesn't inspire confidence and I wonder how many other people are having this needle problem simply because of the time they've had the Webers; I fitted my 151s in 1999 and they've seen 80,000 miles so I think I'll take a look at my needle valves. I'll do it this winter when I take the head off to replace my Cometic head gasket which has a water leak on No. 3 cylinder, fortunately only into the head and not reaching the oil, causing misfiring straight after starting and low compression. The damage may be where it has to be cut away around the oil drainage rubber tube.

Your oil leaks on 1 and 4 were obvious from the photo of the plugs in you first post. The real irony is that you changed the Stromberg head for a Weber one. Yet Miles Wilkins published his personal experience of the Stromberg producing more power with his late series SE cams than most Big-Valve Sprints; the factory checked out his 0-60 times after it was run-in and they were the fastest they'd ever seen.

Yes, one irony is that this would have cost me a lot less if I had just bought another set of Webers and trashed the original set. Assuming the 2nd set had good parts, which I guess is quite the assumption.

What oil leak? There was a coolant leak, solved with surfacing the head. There was an external oil leak, solved by welding up the crack in the front cover. I'm not aware of any internal oil leaks, but as you say, it's been a long saga and I'm probably getting forgetful. I think what you saw in the first picture was the way over rich state given the needles.

You did make me go back and read my first post - the real irony is that Red Line asked me to check the needles - which I did, but I just couldn't tell they were bad, since I had nothing to compare them to and the fault was pretty subtle.

Yes, I know the Strombergs were fine - I was more doing this more out of 'why not' than 'why'. I do have more power now, but that's because I've got a fresh lower end and much better compression.

"What oil leak?" Your post June 18:

"Maybe the bigger issue is the oil on top of the pistons and seeping in front of #1 and back of #4" suggests an oil leak somewhere. No sweat, just my reading of your report

BTW, I've only used a chain hoist to fit the head since having to juggle with the recently fitted 4-2-1 exhaust while fitting it. Actually that was back in 2016 when I was only 73 and weighed 130 lb but I still just lift the head off, or did two years ago.
