Hi Jakob Welcome and happy new year. I love the photos and the work you've done on your niva. You ask me about weber 32\32 DGR. Primary\secondary fuel jets.....................1.30\1.30 Primary\secondary air jets.......................1.65\1.60 Primary\secondary emulsion tubes............F66\F66 Primary\secondary idle jets..................... .60\.50 With bigger fuel jets I had higher fuel consumption (15-16 lit\100km)but not better performance, and black smudge on sparks. As you know weber carbs have F50, F6 or F66 emulsion tubes. The F66 gave me the best performance.Also plastic float is better for offroad. The fuel consumption with this setup is about 11-12 lit\100 km on road - 100km\h The last few months i have install an hho generator so i have about 15 % fuel economy. Cheers Dimitris

Hi Dimitri! Thanks for your listening! I have to order service kit (power valve is damaged) and also will buy jets like you have. 11L is ok... with big tyres and not too slow driving... For me it is a very big difference to my Solex before. Feels much better and sounds great ;D Please tell more about your HHO generator- or is there already a tread? (yet i dont get arranged with this search function...) Is there no problem for engine/ zylinderhead? And cooling System? Hi Jakob I would like to move the posts regarding the bearing and axle arm conversion to technical. Is that in order? Regards Spikes Ja, of course, do so! greets Jakob

For me it is a very big difference to my Solex before. Feels much better and sounds great ;D Hi Jakob When i bought my niva, it had a Solex 21053-1107010-62 carb and AFR module. I don't like to remember that terrible part and the problems which i had..... Some years later i had change it and i had install an AA3 2107-1107010-10....28\36. The last 4-5 years i have the Weber and i love it.....it is the best!!!! At first I had install a DGAV 32\36 but I had a problem with the auto choke......it turned off at 50 degrees and i couldn't tune it. see photos here......... s1120.beta.photobucket.com/user/dim9223/library/WeberNow with the DGR 32\32 + electronic ignition + three-pin spark plugs + hydrogen ........It's a fantastic comprehensive package!!!!! ;D ;D (I added and aceton in the petrol.....but I hadn't a better performance). ;D ;D .........when you rebuilt your weber check the primary and the secondary shaft for gaps.......etc .......after that your niva will run perfect and much better than before!!!! I think that the only problem which you will have with the carb is when you drive offroad over steep inclines up hill....because your niva with the locker diff have a great performance .....much better than mine........ Cheers Dimitris PS. please post some photos of your mods........ - new springs (special production) - new shocks (Rancho RS9000) - Ball joint Spacer in front (4,5cm) - new front wheel bearing (Iveco Daily) - steel front diff. housing (special production)- reinforced rear axle- disc brakes on rear axle (VW Golf)- 100% Diff. lock rear (ProTrack.gr) - shorter Diffs. (4.44) - Winch in rear - complete electric new - complete service to engine - sharp camshaft

Thanks Spike, very interesting to read! I had a Solex 21073-1107010 now for some years. This carb can work very good in niva, but not mine. Alltime problems and never perfect. This weber feels also now, with bad power valve and wrong sized jets better. At moment i can drive "only" about 100km/h. Offroad carb works very good so far, plastic float is ordered Also i will install a fuel pressure regulator. On street 3- 4 PSI, offroad 1,5- 2 PSI will help for good performance. I cant tell about fuel taking, only 200km driven so far... I will create a new post in photo gallery. thanks all for the warm welcome! greets Jakob

Today finally all Weber parts arrived Power valve diaphragm was badly damaged: One of this three metal nipple is little bit used. Its less than 1mm, will this be a problem? On Diaphragm you also see only one touching point. New diaphragm has no metal on this place? Is this correct? Old spring dont have much power left, new is much stronger: : Also i invested into a fuel pressure regulator: Greets Jakob

Hi Spikes and Jakob
I am not sure, but I don`t think the short lug will affect the power valve.

I am not shure, but i think the diaphragm never touch this three nipple in correct condition. This happend only because of the bad spring.
Lets see, will service today...

I did some driving in the Mountains and deep snow. Carb is running ok so far. Problem is full power. I miss about 20 PS. And in very steep and jumps float makes problems. I have same jetting like you show except primary idle jet, it is still old .52 (i did wrong ordering ) Choke dont work well too when engine cold and warm engine die with choke. Today i got the original calibration for DGR32. Here the data: primary/ secondary (1200ccm/ 1600 ccm Ladas engine) Choke fixed: 23 - 27/ 23 - 24 Auxiliary venturi: 3,5 - 3,5/ 3,5 - 3,5 Main jet: 127 - 115/ 127 - 130 Air corrector: 170 - 180/ 160/ 180 Emulsion tube: F50 - F6/ F50 - F6 Idle jet: 50 - 50/ 52 - 50 Pump jet: 45/ 45 Pump back breed: 40/ 40 Needle valve: 200/ 200 Float level (without gasket): 41mm/ 41mm Did you test this setting? Would like to hear your result. greets Jakob EDIT: here the original scan:

Finally i got the last missing jet. Now i have exact the same like Dimtri has: Primary\secondary fuel jets.....................1.30\1.30 Primary\secondary air jets.......................1.65\1.60 Primary\secondary emulsion tubes............F66\F66 Primary\secondary idle jets..................... .60\.50 Runs realy great! Feels like 20 hourspower extra ;D Everything works wonderful, many levels above Solex. Only Choke is much less effectiv. With Solex i can go up to 2000U/min, even with cold engine. With Weber i can only go up to about 1200U/min when engine starts below 0°C. It is no problem, engine never stops, even with lights on. In spring time i will test the original jetting for comparison. Fuel taking i have to keep on viewing. Now, about 40% driving in deep snow, engine takes about 12 liters. I am very happy with this carb. Also my Niva at all never before had so good condition. No vibrations, no loud bearings, smooth engine and very well braking. Oh, i love my Niva so much best greets Jakob

I have no problem with the Choke When you start the cold engine (below 0°C), how high can you bring the idle speed with choke? I can only go up to 1200-1500 U/min. And it is better not to pull full choke, more about 3/4. With solex i can easily go up to 2500U/min, it is big difference. I dont know if it a problem or normal for Weber. Other question to Weber. Next week i have to get my technical control renewed for Niva. that for i refixed the crank case breather on the air filter housing. The carb dont like that and rund very unsteady in idle. Also it is no more possible to adjust the Weber correct. Did you ever refixed the crank case breather and had same experience? greets jakob

Hi Jakob and all you there!!! Here during the winter, the temperature in the morning is typically about 5' C. But also during the coldest mornings I have not problem with the choke. As you can see I have the adapter over the carburator and the original airfilter box.During the winter I adjusts the " Temperature regulator" of the air filter box at the middle position (50% cold air- 50% hot air through the exhaust). Also the "Discharge hose" is normally in its position. With the choke pulled at 1\2 the engine speed is about 2000rpm and you can see at the photo the location of the "Choke plates" ........I hope to helped you!!! greets Dimitris

Around zero choke is enough for 1200U/min, this is ok. But at -10°C choke is not enough for lights on. The mechanic is working fine, everything look same like yours. I also have the adapter. When i pull full so that both cambers are closed, engine stops in idle when warm. And when cold also not that fine. Best result comes from half pull of choke. Weber carbs are more for warmer regions, i think i have to arrange with that. Of course i have the temperatur regulator in use. Below +5°C i use only warmed air. Why dont you dont let the crank case breather to atmospher? Problem with law? I always have it free so all water and bad oil can come out. Carburator gets dirty and engine runs worde swith this hose fixed on airfilter. It is fixed now for six days ans carb is already little bit oily and very wet inside. Also engine oil is white and slurmy. I use the car a lot for short distance. With open hose i dont have these problems. Driving in deep snow with second low red. gear. Full gas, about 3000U/min. Engine runs perfect. Then snow gets deeper and engine go down to 2500U/min with constant full gas. Than i cant go in first gear. Engine dont come up after gearchange. I have to pull the pedal three times until engine slowly starts getting up from 1000U/min i can go on driving Think this is normal for the Weber? greets Jakob
