I have 4-5 I've collected over the years, and the smaller ones can be re-drilled to the larger sizes. If you are using a 009 distributor with a 30PICT carburetor on a 1600 cc DP manifold, the main jet should be X130 or X132.5 and the air correction reduced to about 100Z. Rob notes -- I have a 1500cc single port engine with it's original 30PICT/2 carburetor. I have lowered the fuel pressure down to 2.5 psi and checked the float bowl fuel height. With a leaner 140Z air correction jet in the carburetor) I got 11.6 km/l (27.5mpg US). Rob responded - If you still have a vacuum distributor - yes. The carburetor idle circuit controls how much fuel you have at idle. And fuels! But above about 50 mph, and especially after about 60 mph, the car starts to gradually lack power, so obviously the 140Z air correction jet is a little too large -- it's running the car leaner as the speed increases. Where the early style carburettor has the idle cut-off solenoid on the RIGHT side of the carburettor, that solenoid sits in the back of the idle jet. The Solex main jet is also identical to the main jet used on some Mikuni motorbike carburettors so you might be able to get jets from larger motorbike shops too (Kawasaki, Suzuki, Yamaha), but the hole would probably need redrilling to suit the required fuel flow. The Pilot Jet Valve (idle jet) would be the g55. Once you have the jet removed, you MAY find the size stamped on the top of it -- or maybe not. If you install a single carb on GL (34/3 PICT) always keep in mind the following: 1. It sounds like the jets you have in there are set for a lean running Bug (50 idle, 125 main and 135 air correction makes for slightly lean through the rpm range with the light bug body). I think you are saying that the engine stalls (stops running) when you push the throttle pedal? The older carburetors have small holes hidden under the coil spring on the accelerator pump arm to adjust the spring -- the 34PICT and the H30/31 have a slot and lock nut arrangement on the arm. With the idle cut-off valve working correctly, hot spots in the cylinders don't occur as readily, since there is no fuel available to keep the engine running once you turn off the ignition. Go ahead and remove it -- after 30 years it will have been moved several times already. This will richen the mixture and help eliminate any 009 flat spots. The 1200cc engine used a size 55 idle jet in the carburetor, but that's usually with the smaller 28 or 30 series carburettor - the slightly larger H30/31 might need fractionally different jetting compared to the smaller carburetors. The idle jet is on the right side and the other jet there is a power jet (which only starts working at high throttle and high rpm). If it seems a little rich at higher speeds (plugs sooty after a plug read) then try the 130Z air correction jet. Another question - The car runs terrible but it runs. Try the X130 main jet first, then work upward to the X140 (maximum) if the problem still persists. (You must log in or sign up to reply here. In most cases you can just leave the power jet alone. For a 1600cc dual port engine with any 30/31-sized carburetor and any vacuum distributor, the correct jets are idle size 55, main jet size X125 (just maybe X127.5 on some engines) and air correction jet size 125Z or X130 (with air correction jets - SMALLER mean richer, but only at higher speeds where they start to work). All the plugs look the same -- black and fluffy, telling me a rich condition. The optimal stiochiometric (balanced) ratio is 14.5:1 -- that is, 14.5 parts air to one part fuel. Setting the idle screws (B): Tighten the screw until it touches the carburetor lever. The proprietor of Aircooled.Net thinks the main jet is a size X130, and the idle jet is size 50.) And we will continue responding to emails through until early March 2023 because we are wholly committed to resolving any other issues that may arise from previous sales. The last three carburetors are more sensitive, and so the lack of vacuum advance on the 009 makes more of an impact.

The X127.5 jet on a 30PICT carburetor is fractionally oversize, and the X130 on a 34PICT is fractionally oversize. Checking and adjusting cold idle speed =>page 22-53 Throttle valve positioner Another - You mentioned a bigger jet -- are they available? If the valve sticks in the open position, the idle fuel circuit will remain open, so if the engine is still turning it will still draw fuel through the idle jet, resulting in running on if there is a hot spot in one or more cylinders.

Seller pays for return postage. Note: Regarding "drilling out" the main jet, please see our article on Tuning the 009 Distributor/ To explain, the main jet supplies the fuel, and it supplies too much as the rpms increase (a function of the increasing vacuum in the main venturi).

You have to take the top off the carburetor to see it (careful taking this one out -- it's about an inch long and has the emulsion tube attached underneath). Be careful that you don't tighten these nuts too much -- you may strip the stud out of the base of the carburetor. So with a vacuum distributor, using a 55 idle, X130 or X132.5 main and about a 100 - 120Z air correction jet should provide good mixture for a 1776, without affecting fuel economy to badly (fuel consumption WILL be a little higher with the larger capacity though). The angled one (points slightly towards the rear of the car) is the idle jet. If you look at the two jets you can see that the (angled) idle jet sits in a protrusion (channel) which continues downwards under the jet, towards the idle and transfer ports in the throat near the butterfly. *** Supply-chain disruptions have hampered our ability to acquire/restock items reliably, and a lack of backorder ETA information is the frustrating "new normal" for our hobby.

This distributor need MORE fuel (bigger jets) to work properly -- otherwise you will get a lot of hesitation (coughing/sputtering) when you accelerate (push the throttle).

With lean jetting you are likely to need more throttle and have slightly worse fuel economy - using the slightly richer settings I'd suggested above will give you a little more power and a cooler running engine, so hopefully fuel economy will improve a little, but don't expect too much - fuel economy with the heavy Type 2 body is never very good.
