Im about to bore out a 276 carb to 1& 1/16 for my Ariel .........question is ,can I simply bore out the jet block/slide guide assy as one piece ? ....or do I have to unsolder the lower part ,so that the short tube on the jetblock is unchanged ?...........Unsoldering/resoldering could be tricky so as not to block or obstruct any of the passages or jets...............I see lots of horribly bodged Amals about,seemingly enlarged with coarse sandpaper wrapped around a stick,but they are never attached to engines ..............which Id assume is because they dont work anymore.

I think you’re venturing into unknown territory here. There are too many unknowns for any of us to give a confident answer. You don’t say why you feel it necessary to bore out a carb rather than, for example, just fit a bigger one. More information please.

Ariel is a 1950 VG which came fitted with a 1&1/16 Amal 276.........I have lots of bits of smaller 276s ,and boring a worn 15/16 carb seems to be the best way .........the carb is also needing the body sleeved ,and the slide and guide also sleeved or built up, all due to wear ..........might as well do the lot in one go.
