In the first post, I stated my focus, which has been accomplished. Your comment above is out of sync with this reality. Various issues on this topic have been presented. .I also stated in this thread, Sidebar: FWIW, a brief overview on Weber's DGV Carbs See my first post in this thread, and...

I have time in the carb-saddle with GM/AMC/etc rebuilding...back when rebuild kits were cheap. In carbs' heyday, there were lots of carb rebuild shops in a decent sized city. And guess what, all carbs had to be rebuilt, sooner or later. And if the internet was around then, I'm sure those...

Trivial Sidebar: SU Carbs Main Jets It is a fact, not sufficiently well known, that constant-depression carburettors (like SU’s) are more accommodating, especially for low and medium-speed acceleration, when all is not well with the engine. This is because, in spite of the driver’s heavy foot...

Just lightly digging on this topic, but on a different issue in item 1. 1. BMW Mine did the same thing in terms of leaking, it was a combination of fuel pressure and not having a phenolic plate under the carb, so the fuel began to boil. 2. I do not own a Weber currently, but if I...

Second poster on this British forum gives a decent explanation What causes heat soak, and is it a bad thing? "Heat soak is to be expected...Mostly, on older cars, folks just put up with it. " Years ago, I pulled a loaded trailer with a dually pickup using a carbureted 454 GM on a hot summer...

Was fuel pressure checked? NOTE: Requires fuel pressure be regulated to 2.5-3psi.

If you are using the stock dizzy with the Weber carb, you either have the wrong carb or the wrong dizzy. It’s that simple. The advance profile of the stock dizzy is designed for the stock SU carb not a Weber..............I’d advise talking to Joe Curto, the SU specialist in NY,.. >heat soak...

Oh, another Ford product? Fix or Repair Daily? Cheaper to operate than a GTO? Gas Tires & Oil? >like vibration which Volvo engines (especially the push rod engines)< I notice Anti-Vibration Mounts available, but not for DGV/DGAS carbs. Is it possible Weber has improved their carb? I'm not...

I might suggest using a blended mix using E85, but "Currently, there are no public E85 gas stations in the State of Alaska." Venturi can't be changed, but making a point here about different sized venturis: so, when other changes are made to this carburetor, there are tradeoffs. If fuel...

Best I could find...I assume Bosch (not Volvo) setup these vehicles. I did say, "Based upon LH and EZ diagrams," which means those diagrams presented here. I do know ignition switch contactors can get hot, which can decrease output voltage. With an ignition switch replaced (or inserted into...

. I do have LH 2.4 service manual, but it may not be relevant. Diagram: Bosch Fuel Injection EZ 116K Ignition system, B230F Based upon LH and EZ diagrams, the ignition switch powers each box on different circuits. LH 2.4 may have one or more safety circuits built into it, and lower battery...

Sidebar - Years ago, my 1984-245's alternator shot craps...at some lower battery voltage, engine shut down. A new ignition switch could be inserted into electrical plug, and manually turned, fwiw.

Apparently, this video I cited was not watched. Ruling out an ignition switch issue is prudent....

In carb heydays, I recall GM had at least one jet size listed for a higher elevation. Holley explains what to do for higher elevations. With Weber's carbs, more fine tuning options exist. When jetted for sea level, as elevation increases, the mixture gets richer, but if jetted for say Denver...

YMMV, last diagram I saw, quite a few amps runs thru ignition switch. Back probing has been used by shade tree mechanics, and can give false results. There still can be current flowing thru the switch. Oh, the mechanic does the hot wiring, for testing.

If ignition switch's plug could be pulled off and hot wired, this would rule out ignition switch.

These are 2-barrel, progressive, down-draft carburetors that are designed for 1200cc - 2300cc sized engines. 32/36 DGV sold in US, and 32/34 DGV sold in Europe were designed mainly for fuel economy, and 38 DGAS or 38 DGES for better “throttle response at a slight penalty in fuel economy.” In...
