Downdraft Webers rattle apart on volvo pushrods
Hello Guest, welcome to the initial stages of our new platform!

Millions upon millions of people driving billions of miles for decades with downdraft DG family Webers disagree with your single, isolated opinion.
Maybe you didn't do it right.
I use star Tron in vehicles that sit for the winter. You guys have no idea how crappy California gas is. We get the worst gas in the country.

Hiperformance rebuilt my hif6's. Local SU master is gone. Your guy Steve said he's not very good with them. Only thing that's going to cost is having custom brackets built for the SU linkage. I had a bracket built last year but it was attached to the rear head bolt and I don't want to do that again. Weber offers a lot more options when it comes to linkage.
The biggest problem is that people are just scared of SU carbs. I'm not sure why, they are one of the simplest to understand and are quite easy to adjust.
I mean, I get it, carbs with manual chokes are just this way. Some are worse.
I ran HF6 SUs, HIF SU, Stromberg Carbs (as delivered in '70), and the DGEV 38 carb. The DGEV gave me more trouble and poorer performance of any of them. The worn out HF6 carbs were the best. In fact, I chose the HF6 carbs with leaky throttle shafts over the DGEV.

BTW, SU carbs were used on the Datsun 240Z and are still serviced and repaired for them. Try a web search for Datsun SUs, and you will find a bunch of results. https://sucarb.co.uk/ is also a good source of information.
My cars with SU or Strombergs never had any starting issues. They didn' thave any running issues because you aren't supposed to drive them with the choke on. So you have to warm up the car enough so you can drive without the choke. A small amount of choke was ok if it was really cold but the general rule of thumb was to warm up till you don't need the choke.
I used to run webers on my porsches and VWs all year round. No chokes on them or warmup enrichment. Just have to warm up enough till it drove.
The SU hif6's are definitely a performance upgrade compared to the Weber. Unfortunately I'm experiencing a fair amount of heat soak with SU's. Found a DGAS Weber in my carb pile but I think I'm going back to the 36/38 progressive. Performance is not the #1 goal when it comes to the PV Jeep but fuel consumption is when were often 100 miles from civilization.
