Re: Artificial Intelligence to Design Lightweight Parts

This is cool. Great use of AI.

As other has commented: hit the return- tab, and the part comes out at the other end of the cable.

Re: Note on Weber carbs by Mr. Passini

Alot of good input here. Never thought of doing changes to oritentation of the carbs for them to line up; check placement of studs (redo studholes or use offset studs...) and have precicion spacers (nylon or other hard non-conducting material instead of the two layers of cardboard gaskets currently ...

Re: Note on Weber carbs by Mr. Passini

I bought his little green book in the late 70's, while working on my '76 Fiat 131. I remember he said your plugs should be the color of Cadbury's milk chocolate. Another gem, "Suck it and see" (to find out if something will work). Anyone who ever had a Cadbury bar, know he's correct on that stateme...

Re: Note on Weber carbs by Mr. Passini

Great input. If any other reson to open them up, it must be well hidden. As I undertamd, AFR would go leaner by opening the bypass as this air would not draw a corresponding amount of fuel. As you state, Bill, Passini too say a small tweak of the idle mixture screw after opening the bypass may be ne...

Passine say (page 57 of 1993 edition of»weber carburettors»: ‘When the two carburettors appear to be belanced, with the mixture appeating to be about right, then each each air bleed screw should be opened half a turn,...’ Well- I’ve never done this, ...

Re: Sizing IR Carbs

You have probably seen the graphs/ tables with choke or bore size vs rom band for given cylinder volume?

There are some flow data out there too, but given sll the tuning done with webers, probably good enough ro follow paths already walked?

Re: Sbf oil pump for 8000 rpm

Walter; hi! Anything I can do to a Melling 10687 to make it do it’s job at 8000+ rpm?
Any pics or links to the grooves you described earlier would be great, too.

The best I could do tight now as the spacers and bolts are to short to put it another 1/2’’ reareards.

Re: Vacuum pump install; engine plate

That was my thought too... I think; Plate not too wide..... Cut a piece of the bottom out- putting pump low, leaving as much of the plate as possible. Will have to check clearance for filter and tubing, but I think you got me in the right direction... BTW: Not much info on this pump to be found. See...

Vacuum pump install; engine plate

Yes;invested in a CVR vacuum pump; fitting kit and a Moroso Mandrel drive not long ago. First time out doing something like this; and first time doing a race only engine as well. Guessed there was no harm getting some In HG out of the crankcase…. Installing on a SBF 302 with front engine plate. I'd ...

Re: Spark plugs- ground strap”tech”?

Maybe the sharp edges of the holes make it easier for a spark to jump to, compared to a smooth surface. I seem to recall David Vizard some years ago advocating this mod for that reason. Giving higher probability of the plug fireing correctly. Maybe can go to a bigger gap than without the sharp edge...

Re: Spark plugs- ground strap”tech”?

Haha The best thing I have done is grind the strap away from the center electrode to the gap you want. Yo... what difference from bending the strap to get correct gap? The strap would be to the side of the center electrode not over it. Sorry, misread what you said ... "away"... Seen any difference ...
