Hey guys, Courtney here. I haven't posted since my last update on getting my orange Pumpkin Z home. Everything was great, until seemingly overnight, the car started to give me problems again... Last time I messed with it and fixed it, I had adjusted the timing to further advance it, and that seemed to fix the issue. After a fresh rebuild on the dual Webers, I thought for sure that I would have a good chance at getting the setup to work. Now I'm finding that it's not that simple. I took the car out around town the other day, and it started bogging. I now can't drive it over 2k rpms, because it bogs that badly, and honestly, it's a little scary. It even backfired from the carbs once, which was an issue we had before, but thought we had fixed when we adjusted the timing. (The timing is currently fully advanced.) At this point, I'm looking for any advice I can get. I've been told that dual Webers on Z cars can be the most difficult setup, and that running the stock SU carbs is the best way to go. But I've also heard that if you dial in your Webers correctly, they can be great. I'm really conflicted, and since I have no history on these carbs other than the fact that I rebuilt them, I'm not sure what to do. Ideally I would like to keep them, but I won't be able to decide until this mystery issue is fixed. If any of you know 510s, you probably know who Troy Ermish is. I'm thinking that I might just take the car to him, since he's local and builds race 510s running dual Webers all day long. Any advice or ideas would be appreciated! Thanks guys.
