One more "someone told me" makes a difference? Since I'm not into ice racing, I think I'll go ahead with my original plan.
Denny, you may be correct that Speedway has pushed manufacturer to solve issues. My personal experience has been that if they run correctly out of the box it will most likely be ok. But if they don't they pretty much can't be fixed because it is a casting or machining problem. SherryBerg is the biggest manufacturer in China for most of the knock offs of carbs, distributors, fuel pumps and such. I had an engine builder build a big bore VW motor for a 21 window I built and he used SherryBerg weber knock offs. I spent hours trying to get those carbs to work correctly. Genuine weber jets would not screw in properly among a multitude of problems. Never did get them right but it was customers choice. I just stay as far as I can away from that stuff because it just causes me grief. And at our age we don't need it.
I say go for it. You have the knowledge to tinker and tune. If it works, or at least is workable, you would, I believe, give an accurate account. I await your findings.
Old saying "One good test is worth a thousand opinions ". Let's see what the result is on this current purchase, and then can either validate or refute the opinions. I do agree the UK 97 is a nice quality part. Also agree some past problems with the Chinese knockoffs. Sent from my SM-A102U using The H.A.M.B. mobile app
For the most part many of the overseas manufacturing facilities only reverse engineer items that are supply to them. With that being said, if you send them a poor design you are going to receive a poor product.
I am going to put "my money where my mouth is", but it will be at least a month before I know anything. I have another week or so here in Florida, and when I get back to Minnesota, I will be immediately changing residences there. I will order the carb when I get back and expect to be settled in by the first week in May, so I will have at it then. I have a fresh 258" 8BA on my test stand that I have been using to test other carburetion setups, so I do have everything I need. The test stand already has an A/F meter and sensor, so that should help. If one runs good, I'll have to buy another and run them on the Navarro "Universal" dual manifold that I plan on running on the ultimate version on this engine. Then I'm done; I don't do triples.
LUCKY TOOK 4 OF THEM, RIGHT OUT OF THE BOX, AND RAN THE SHIT OUT OF THEM AT BONNEVILLE. UK STROMBERGS, OR NOTHING! CHECK OUT HIS VIDEOS ON YOUTUBE....I'M GETTING 2 FOR MY COUPE.
" 36cab " I am sure there was an article posted in Custom Car magazine about these 97's. Will see if I can find it. Just found it.
Yup, Brading, Speedway doesn't sell Stromberg brand carbs. They sell their own copies, called 9super7. Not sure if you can access Speedway's website all the way over there in the UK, but it would show on those pages that the carbs are not real Strombergs.
Hands up, I made a mistake. I took it that the picture posted by nochop in #13 was of the Speedway ones which it was not. Have had a look on the Speedway site and can see the difference in the pictures. Cheers Guys.
There is no such thing as a 'Speedway 97', their product is a 9 Super 7. Of course it is passing off and they are relying on the similarities/confusion/ignorance for sales success. Not to mention cheap price.
So if Speedway sent them a worn out beaten up mangled by every owner since 1936 Stromberg 97 , they would get back a replica of a worn out beaten up mangled by every owner since 1936, Stromberg 97, but made out of shitty materials and machined by people who have no idea what the item they are working on is supposed to do. BUT it comes in a nice clean (but stinky) cardboard box , with Chinglish instructions and safety warnings. Here is what Tim McAmis has to say
Pretty much, but remember it is our own manufacturing owners that slip the work overseas to save a couple of bucks. I agree with Tim.
I do a lot with chinese suppliers thru work. Your comments above - it actually works in reverse. Over time the chinese manufacturer will start outsourcing portions of the assembly to other suppliers, generally in western china. The stable manufacturing process can go to shit as this happens. Consider 10 yrs supplying to speedway making everything in house, then they can sell in open market, no need to meet speedways quality requirement anymore, so they outsource half the components with a close but not the same specification to lower their cost point or bump their profit. It may be the same company that supplies speedway, but is likely not the same specs. I see this frequently, tryout parts are great, first 6 months of production great, all of a sudden, drastic differences. Reject the parts and find out they " moved production to our partner company" its a straight violation of PPAP.
Age, health problems, and other projects got in the way. By the time I looked at it again, they were no longer available. Sorry. "The road to Hell is paved with good intentions."
