Webber carb

Mmm. A hand throttle would be handy, I'll have to ferret around for a IIa one.

Fuel tank shedding it's inner lining of rust, I suspect. I've just changed a fuel tank on one of mine as I had problems with fuel starvation. Mind you, not before I'd changed the fuel lines, swapped a carb and fitted another fuel pump. But it kept blocking up the pickup tube, and I got sick and tired of attempting to clean the tank out, after having to remove the tank for the third time, I replaced it with a new one. That damn filler hose on a SWB Series is a bitch.

Glad to hear you say that! I suspect a badly-fitted filler/breather on my 2a. PO fitted a new tank quite recently, but if I fill it up to the brim of the filler tube it p*sses fuel all over. 9/10 full, no problem. If the filler tube is a bitch to fit, that would explain why it wasn't done very well.

Any suggestions or hints for when I take it apart and put it right? Is the cover behind the bulkhead meant to screwed *and* riveted in place?

TIA

Just screwed in on mine. However, the replacement hose obtainable is not the correct one for the vehicle, I believe it is for a 90 instead. Whilst similar, it does not have the same curves, and I had to enlarge the holes in the bulkhead and the rear tub, to avoid chafing and cutting the new hose. Also, the new hose is a better material, but the rubber is twice as thick as the old one.

It's possible that yours may have been changed and chafed, which would make it leak.

Word of advice - it is 100 times easier to fit the hose if you unrivet the fuel filler from the back tub, and remove it. Fit the hose in and then fit the filler neck back into the top of the hose. Attempting to do it without removing the filler is damn near impossible

Funnily enough, it's a piece of piss on the 109", as the filler is all on one side of the bulkhead.

I thought you might say that - oh well, out with the rivet gun again.

Thanks for the advice.

Rich

Well, you can try it without, but you might save yourself time by unriveting it in the first place.....

Alex

Oh, I always take rivets off with a rivet gun. It takes longer than with a drill, but it's much noisier and more satisfying.

Had a proper look at it over the weekend - the screws holding the pickup pipe and the blanking plate on the tank were finger tight only, and the fuel was pouring out over the top of the tank when I filled up. I've screwed them back in fairly tight, with a good coating of hylomar on the cork gaskets, and it seems to be OK. Thanks for the help.

I agree entirely with the Weber rough running comments (after a cold start). Fine in summer but as we hit the colder weather I get the stalling/rough running for the first few miles - a swine when you hit a traffic jam as soon as you leave the office.

I also agree with the comments about SWB fuel filler hose - the hose shape didn't seem right and I had to enlarge the bulkhead and disconnect various bits to make it work .. even then the hose seems uncomfortably taut ...I am sure that's why the old one started cracking under strain!

doesn't need a warm air input does it? might be icing.
