Was easy back then with carbs.
No looms to cut and splice. No immobiliser and sh!tty sensors.
Just big carbed engines and a manual choke lol
Easy, but they were sh!t.
The fuelling was a guess, they would need tuning monthly, wouldn't run well in winter/summer, depending on which you jetted them for etc...
But boy, oh boy, did a set of 40/45 DCOEs sould good!

I'm pleased carbs have gone.
You can now build a high revving, high compression engine on 45 ITBs that will take full throttle at 1500 RPM and pull to 9000+...try that on carbs.
