The 1.7L car I’m working on had a single carb set up on it when I got it, which I removed to clean engine, replace some seals and paint the tin. I was a little surprised that the intake runners had none of the phenolic blocks at the head area. There were only thin aluminum gaskets there - 4, one at each port. I want to verify that the stock “blocks” removal is correct and that the individual thin aluminum gaskets are the best option. There’s probably not any difference but I was considering these ones below, thoughts?
Also I have a partially complete 1.7 D-jet system, maybe I should bite the bullet and get it up and going instead.. but I figure the single carb will probably get the car running sooner and keep me motivated to mess with that later. Here’s the gaskets, they’ll work, right? https://a.co/d/04zbW7Cv . |

With single carb you actually want heat to get into the runners to the carb.
Those long runners tend to allow fuel to condense and drop out of the atomized mix. The warmer the runners the better they help keep the fuel atomized & in the air stream. Complete opposite of dual IDF’s or Dell’s. |

The part about warmer runners helping with atomization sounds logical - So, not much chance of causing a situation where the fuel boils and causes hard starts etc, from the carb sitting closer to the hot engine? . |
