Cool, how did it work and were you able to sync your carbs so they now run well?

Awesome! Are the small center holes large enough to allow air into the carbs to function correctly while you are making adjustments? Also, where do I get a drill bit like that? And in conclusion, what will it cost me to build my own?

sorry my mistake

the synchro can not work as it is in the picture,

after trying it i realised that the vacuum meters can not read anything, the holes were ok for the engine running, but too large for the vaccum meters to have any suction

but the good news, is that i can use the vacuum meters and the rest of it without the bowls

the final installation is this one, use only the vacuum meters and the tubes and connect to the hoses that come out from the carbs, as in the picture:

they work great, see here after synchronising:

components:

vacuum meters scale (0 to -1 bar), max error +- 1,6%, adapting materials, silicone hose diam. 4mm (exact one for the carb hoses)

the total cost will be less than 60 euro, but i do not know where you can find them, nowadays is getting more and more difficult, nice that i have a supplier nearby with plenty of these things, :mrgreen:

i recomend you this thread to follow the procedure:
