Thanks in advance for your expert advice!
I’m current running a single ill performing Weber 32/36 progressive carb on my 73 1.7. Before I rip and replace it, is there anything else I should be considering? Any thoughts on dual carbs? |

The problem with a single carb is that the fuel does not stay suspended (mixed with air) in the long length of the intake runners
Remember the carbs job is to mix the fuel into mist mixed with air The long intake causes the droplets to pool and drip out of the air mix The fuel lnjection system only carried air without fuel in those intakes Twin carbs with shorter intakes will always mix better…. Physics |

And there's a ton of knowledge and support now for those systems, such that ripping it off and replacing with a single carb just isn't reasonable any more. But that said...yeah, duals are much betterer than the single for overall driveability, especially in varying ambient conditions. - GA |
