so the a15 stock carburettor would be fine on the stock a12

my car seems to not start it cranks over, had the auto elec do the dizzi so its got spark
my mechanic said theres something making the sparkplugs foul and not wanting to spark
he also said it sounds like its not getting enough fuel with the new carbi and the fuel pump is good

A weber 32/36 is a fairly common alternative, these are available on ebay or via the classifieds.

I personally like the weber 28/36 DCD variant but that is just a preference.

If you get stuck I have some weber carburettors but the freight is so expensive from me to you.

Good luck. Chris

they ran ok no problem at all. yes a15 carbs have different jets, but they have different venturi too.

I ran a stock A15 carb on my A12. It ran well, but not perfect close to idle. So check the float level.

Bigger jets doesn't mean richer, since it is the combo of main/air that matters. Also A12 and A15 carbs have different venturi sizes, so same jets will act different.

pretty sure the a12 carby has bigger/better jetting than an a15 one.
i may or may not be correct though so wait for someone else to give their thoughts.

would a a15 carburettor work on a stock a12 motor i put it on and it doesnt seem to be pulling in enough fuel or its flooding

whats the best alternative carburettor for a stock a12 motor instead of the hitachi

also wondering where to buy
