I always suspected an air leak when it was on my truck. The rebuild kit included a bunch of O rings and 2 seals for the butterfly shaft. Tbh I wasn't convinced they were very effective at all but fitted them anyway. It's an annoying issue as it doesn't really make sense, probably going to end up...

One for the carb guru's. I changed the Weber carb on my S3 109 for a new unit a couple of years ago as I could never get to the bottom of the problems with it. Afterwards I put a rebuild kit onto the old carb & put it into storage. So last week the carb on my wife's 88 starting playing up with...

So spent more time on it yesterday, the carb has certainly made things a lot better and advancing the ignition almost cured it. Went back to my first instinct and started swapping plugs out again. Yep, traced the last bit of misfire back to a failing spark plug. Swapped the lot to be sure but...

So todays tinkering has shown that it runs better with aprox 10' of advance at tickover. Most of the misfire is gone but it is still there. Mechanical and vac advance both appear to be working. Is it possible that I have the wrong comb on the front of the timing cover or that it was bolted on...

Not sure where that leaves it then. Carb, dizzy, coil, plugs & leads are all known good. Timing is spot on as are tappets. Couldn't find any issues with fuel supply, running out of possibles??

Already changed to a new pump and no difference other than the fuel filter is full now.

Well I think we could have a candidate, just tried the compression tester and getting 150 on 1, 2 & 3 but cylinder 4 is down to 120. Squirt of oil got it up to 130 but still a good bit down on the others. Before I pull the head off are there any other tests I can do to check valve seats?

Plugs are a little on the rich side after changing the carb but were perfect before, just need to get the mixture dialled in a bit better. I'm using the plugs from Accuspark that have the triple arm around the central post so gap is set but would seem they give a nice fat spark. I haven't...

Yes I've been trying to do a bit of fault tracing by swapping things. The ignition was done a little while ago but I've swapped coil, dizzy & plug leads this weekend to no effect. Going to do a compression test and see about rerouting the fuel hose on Monday & see what we get. Cheers

Haven't done a compression test no but I'll add that to the list. Fuel supply appears good the new pump seems to be belting it out but yes the pipe to the carb does run across the rocker box, simple to change so I'll add a longer hose.

Hopefully one of you guys can point me right here. My s3 2.25 petrol has developed a low to mid range misfire with wide-ish throttle openings, imaging you slow down for a junction, nothing coming so 2nd gear and keep going, well it misses like crazy till the revs are back up and it smooths out...

Hey all, So I bought a capstan for my S3 last year and it came with a great long length of 1" manilla rope that I didn't give a lot of thought to and just assumed that's what they're used with. Turns out not so much, it works perfectly fine as long as your paying attention but I really would...

Thanks Blackburn, I've done a screen shot of the 2v levers that I'm after just to clarify, looks like you've extended yours on 1 of the pics, I assume that gives finer control?

Ok thanks for looking, hex that's exactly what I've got as well.

Hi Doobie, did you get chance to have a look for those hand throttle bits? Cheers Jon
