You're a fantastic teacher, discussing the basics and then showing it in practice makes this very easy to understand. I'm about to swap a very tired set of twin SU's on my 260Z for a triple weber setup, this and your next two videos are going to be invaluable. Bravo!

This dude is legit... I'm basically a kindergartner when it comes to carburetor function and this guy made a semi-complex carburetor seem simple - and it all made practical sense!!! Most car techs won't give you a drop of knowledge. This guy knocks it out of the park. Wonderful... wonderful.

@@D3Sshooter I have a pair of Weber 40 DCOE carbs on a 1960 Mercedes-Benz 190SL. The car is reluctant to start from a cold start after sitting even for a day or two. Priming it with fuel through the air intake allows it to start immediately and it runs just fine after that. I don't want to burn out my starter trying to crank from a cold start. Any suggestions on what adjustments may be needed? The fuel pump is fine and the hand primer lever gets fuel to the carbs.
@D3Sshooter3 жыл бұрын
@@troyroberts8568 , What I read seems not to be a cold start issue, but more a time/fuel issue. It almost sounds like your fuel chamber runs empty or low when the car sits for a while. There are several possible reason for that, first a fuel chamber leak and fuel escapes , but I guess you have no fuel leaks spotted, second the fuel evaporated due to heat build up and or flooding when the engine stopped. Have a look and test the car with a warm motor, stop and wait a few minutes ( 5) then start... if its hard to start you might have flooding issue... check your float level first. Third, your cold start circuit might be clogged as it starts with priming fuel through the airfilter. Does it run good after it started on idle ? In each case start with the float level check, then check the fuel pump pressure and volume..... Might be difficult with a mechanical pump as it is needed to run the engine so you need a T piece for you meter. Here is what I would do: disconnect the fuel line on the carb. connect a fuel bottle or canister to the carb and hang it up high ( higher then the carb) and let gravity do its thing by filling up the carb. Let the car sit a few days, then start it in that configuration. If its starts and the fuel level in the bottle did not change over the days then its not a carb issue but a fuel supply issue. Best then to replace the fuel pump with an electrical version. If the fuel level went down before you started , then you have an issue with the carb itself , maybe the needle valve, the float etc... and that should be checked. If it does not start, check your idle circuit . Another check is to pump the gas pedal a few times rapid before starting and while doing so have someone look inside the carb and check that fuel is squirted in.... Then start ( that should work) ... If you did not see the fuel been been squirted in then you have a fuel level issue or acceleration pump membrane issue... Does the car accelerate fine when driven ?
@troyroberts85683 жыл бұрын
@@D3Sshooter In full disclosure, I'm not the one working on the carbs. The mechanic that restored the car had cleaned the jets and done everything except put them in a parts cleaner. He said the car runs great and idles fine after starting it with some starting fluid or fuel manually put in the intake. The car will hot start after a short time, but if it sits for hours or more, it will not start at all. There are no noticeable leaks and no fuel on the garage floor indicating a leak.I'm not sure he has driven the car after starting it or is just trying to make sure it starts in all cases. When I gave the car to him, I did notice a small metal ball about the size of a BB that was very similar to the ball in your video used with the weights next to the accelerator pump. This ball was outside of the carb and sitting on top near the wing nut that holds the top cover on. I assume this ball and weight act like a check valve. If the ball was missing, would this allow fuel to backflow and empty the chamber causing it to be hard to start?

Thank you so much for explaining Weber DCOE carburetors. I have a ‘73 Triumph TR6, having reliable power problems which I suspect are due to my 50 year old Stromberg carburetors. I’m considering changing them out to Weber downdraft carburetors, +/- $1300 U.S. before labor, or Weber DCOE sidedraft carburetors, +/- $3,000 U.S., before labor. I’m in the U.S., where carburetors were fitted rather than fuel (petrol) injected for emissions reasons. No need to worry about emissions now as the car is so old the government doesn’t check for emissions anymore. I’ll tinker with the Strombergs some more before probably considering the downdraft Webers for budget reasons.

Thank you for the thorough approach to this topic. Although carburetors vary, the basic principles and functions can be identified in most, so this tutorial also served as a basic introduction to the mechanical fuel delivery system in it's own right. Webers were originally on my mind for their current supply of spares, gaskets and customizable parts, unlike my current Mikuni carburetor which hardly has any spare parts available for it in my region. I use my carbureted Honda engine daily, so user-friendliness, availability of spare parts and familiarity is essential for keeping the engine sharp. I'll go through and troubleshoot my carburetor now that I've been inspired by your video and see what I will end up using on the car on a regular basis. Edit: Also, did I by chance hear a Swiss accent? My apologies for not containing my curiosity.

The only thing that is importend for idle, is the idle jet and air correction jet for idle... and the position of the butterfly for the progression holes. so the 55F8 should be good... did you check your mixture ( colortune, AGR or CO meter) that is always a good indication if you run to lean or to rich on idle.

Back firing into the carb ? Or exhaust ? In each case its to much unburned fuel...

Just tuning my DCOE 45's on my Lotus 907 engine, it's always a difficult task. Best way to put it that there are essentially 3 carbs in one in the Webers (4 if you count the choke circuit). The idle circuit (which is a bad name) handles 0-3000rpm, the main circuit goes 3000-redline, and the accelerator pump circuit handles the heavy loading under throttle. You can get one right, say have a good smooth idle and nice accel to 3000, but then under hard accel it doesn't run well, and then doesn't run above 3000, etc. You can have 1/3, 2/3, etc. working. Proceeding to tune each one is the only way to get to a good situation, and understand how the emulsion tube works to transition.

Indeed, circuits are one thing , but the transfer inbetween is the most difficult part to get right...

I ran twin DCOE40 Webers on my Suzuki Samurai several years ago. Loved the sound of those thru open K&N filters! Gas mileage wasn’t so hot tho.....

Thanks a lot for this great and very clear video. I can see a small hole on the wing-nut (jets inspection). I guess this is to secure them with a piece of wire? Mine hasnt and I am considering drilling a hole

D3Sshooter Thanks. Noticed something today, checked the spark plugs after running, cyl 1 and 4 ok but 2 and 3 black (dry). On a 1380 A series engine with Weber 45. Mixture too rich?(weird on cyl 2 and 3!) or valve clearance? Thanks in advance and keep the great work!! Cheers
