Re Fitting Stroms after Stag Weber

[Mike J]

I am refitting my Stroms to the Stag .After ditching the Stag Weber system .( after a lot of cost and faffing around) Have a couple of Pipes that dont seem to make sense, not surprising . Have included a couple of photos. Just wondering if any one has got a photo of how it should actually go together .
Also engine seems to run at high revs when breather is connected. Any ideas. I know its Sunday afternoon . If any one can help I will be very grateful.

First thing is to ditch that clear plastic hose. It has no place anywhere near a car fuel system. My car had some fitted when I bought it. When I went to remove it, it snapped. It had turned brittle under the effect of under bonnet heat and petrol. Buy quality ethanol-proof fuel hose from a reputable supplier (not eBay). You need 8mm hose from the rear to front plastic hose to the fuel filter and from the fuel filter to the T-piece, then 6mm from the T-piece to each carb.

I know it needs to go. Job for tomorrow. The car had it when I bought it 15 yrs ago , I have fitted proper stuff elsewhere. Just wanted to make sure the old Stroms were still running OK. And would you believe they are!!!!!!. Today. Just cant work out where that blooming pipe goes, My workshop manual seems to be missing that page. Will look at Rimmers.Thanks for the advice.

The engine should run "better" with the crankcase breather sysetm on and the oil filler cap in place - tickover should be set in that condition. The check that the breather system is working OK is that the engine tickover should slow and/or run badly when you take the oil filler cap off.

I think (not toally sure) that your mystery pipe is the fuel overflow , which should run forwards, not backwards. And be in decent pipe, lol.

There is a post in the tech section that whilst it doesn’t show a picture has a description of all possible hose connections on the strommies and where they go . The only caveat is that the vents that are open at idle go to a pipe to the floor on Uk cars, there is obviously no carbon canister.

Running brilliantly at up to 2.5 K Will take it for a blast tomorrow. No more oil pouring out from every join in the carcass of the engine block. Sorry I forgot the fuel overflow goes to ground. Thank you everyone.

Great news. You can't beat the original parts that are designed for the car by experts.

Not even by fitting EFi , header tank and electric fan ?

EFI is great but it seems that it would not be any good for an engine like Mike's.

does this help, the overflow from the offside carb goes under the carb float chamber, will try and take another photo

Good that you're happy with re-fitting Strombergs and hopefully all will be well. It does beg the question though - why you changed to the Weber 38 dgms via Stagweber before and what will you do/have you done to be happy again with the Strommies? In defence of the weber conversion: I had a lot of trouble getting my old Strombergs to run smoothly and stay in tune together. I opted for the Weber and also opted for the additional breather/catch tank for the obvious reason that it is needed and, IMO, should be part of the standard kit. Anyways, I find the weber works very well. A true test would have to be same engine fitted with really good Strombergs versus Weber with breather kit. Probably not too much in it!

Right as always Roger You can't beat proper multipoint EFI as the fuel, ignition and many other parameters are tuneable across the whole operating range, something that carbs cannot do. However some carbs do it better than others. Shame that EFI wasn't about in the 70's.

Thanks John, but I am not always right as SWMBO constantly reminds me . Not sure how reliable the electronics would be in would be in a 50 year old EFI system, let alone how difficult it would be to get parts to repair. Think I'll stick to stuff I can fix with a big hammer

This car came to me with a set of Stroms, but when I come to put it all back together after reassembling the engine, I just couldn't be bothered with all the pipes and cables and tweaks that are needed to get them to work, assuming they would work.

So I fitted a Weber, in next to no time, fired up and now it runs like a dream, with no oil leaks either just as expected, so no need for a catch tank or breather kit.

Respect to the diehards though, you are true heroes!

What mpg do you get on a run? I recently did an 800-mile trip to the Lake District. This comprised of 70mph+ on the motorways where possible, 200 miles around the Lakes (hills, narrow lanes, small towns), stop-start around Birmingham both ways, and over an hour of stop-start on the M5 around Bristol in 30 degrees on the way home. Averaged 30mpg on Strombergs using supermarket E10, no additives.
