Hi there I am looking for a number of 250 size jets to suit weber 48SP. They were made by D&G Valve Mfg Co. Vernon st stoneham Mass If anyone knows where I may obtain these I'd be appreciative

Thanks Andrew

I have a pair for 40 DCOEs if you want them.

Andrew, the family business that used to manufacture grose jets closed some years ago. I will check my shelves to see if I have anything left, but I have sold them out some years ago.
You may want to look at alternatives. I really liked grose jets as well. Too bad, I gather the father passed away and the lawyers told the two sons to get out of the business...the litigious risk was too high.

Best, Tom

Hi there Tom. Thank you for your response ! Certainly a great product , one wonders if the two sons would consider selling the blanks/moulds etc. Would appreciate alternatives but to find some Grose originals would be great ! Check out YouTube. Andrew ralt rt4 winton. You can hear the engine being flooded by the old gross jets failing

Cheers Andrew

We put grose jets on our FCR41 flat slide carbs for our carbureted zx10. So much better than the original float valves that stuck all the time, and we could eliminate the fuel pressure regulator too. Well worth changing them out. Good to see they're still available.

The ones in the E-Bay link are conventional needle valves. The do have a ball on the end but they are needles.
The Grose-Jets use only a ball and fuel exits through six radial holes.

Dan came through with 2 he had since that 2013 post. I can't find my keys on some days.
I'd love to find more Grose-jets. Plenty of them suited for Ford Model A's and SU's on e-bay but none for Webers.
Maserati site in Oregon has them in size 200 for DCNF carbs
