2 Different Solex 26 VFIS Carbs. Which 1 for an 11e?

[drpete]

Here are 2 different carburetors, both model 26 VFIS. The one on the left has its numbers on the lower body half. It also has a serial #727746
The one on the right has its number marking on the upper body half, and it has no serial # that I can find.
I'm trying to find out what year(s) each of these was used and which one I should use on my '51 11e.

i have one working on a motor here . i bought this one as a spare on the samba . i bought a rebuild kit on ebay and re worked it myself . it looks better than the one on the motor so i mounted it on a board and displayed it with a air filter up top for a while here in the house ..... the wife wasent as impressed as i was LOL

The 26VFIS throat diameter is always good to check, I have seen so many industrial carbs in cars, and they don't work well. The correct stamp is 21.5 when industrial is 20. It's possible to enlarge, also jets could be wrong. Main jet for car is 120.

quote - Both have another (different logo) seen in my first images...near the pivot point for the choke on the side of the upper half... Not sure who or what company that represents...

here's the answer from another thread

[my3bugs]

is there somewhere i could get a 120 jet ? this carb came with a few spare jets but not 120 . came with a 180 and 170 and a 945 and a 950 on the side of the carb .....


and i am not seeing a 21.5 stamp anywhere ???

[my3bugs]

ok i found the 21.5 stamp inside on the venturi

[my3bugs]

OK another member helped me ID the main jet , its the small one at the bottom of the bowl . i couldnt read it very good so took it half way apart n got it out . mine looks to be stamped 1.0 ??? not 120 ...... are these jets available anywhere ?

my air correction jet is 180 but i have an extra 170 ??? someone told me the 170 is correct ?

and on the outer side of the carb i have something marked 945 , and an extra one marked 950 . dont know whats correct as original ???

any help , tips or information is appreciated ??? im rather a carb dummy but i try to do my own work .....

trying to show ya pic of the main jet looks like 1.0 or 7.0 to me ? says solex on the other side . if you double click the pic it enlarges .

i have it soaking in some cleaner now .

This 1.0 is not the main jet which is located on the large side bolt with 14 mm wrench head.

ok i have a lot to sink in here . thanks for sharing this info and part links Guys !!!

Mika i took off that 14 mm bolt and indeed it has a 0120 marked jet inside there .

i swapped the 170 air correction jet for the 180 i had .

for the pilot jet i installed the g45 but have a spare marked g50 .


still trying to understand a few of these parts like
pilot jet air bleed 1.2 i THINK that is what i have marked 1.0
spraying well interior 5,3
emulsion tube 0

i do have a scale i can weigh the float with to confirm that .


i liked this chart just cuz its in English

[my3bugs]

we havent heard back from the OP the last day or so . in part if he is watching where im at it should help him as well as neither of his look complete . mine is also a 51 im working with .

looks like he might have enough parts to complete one of em .


found a website that has a few parts available wile looking for good a schematic

[my3bugs]

with each new piece i am able identify and confirm its the correct part number n such im feeling more n more confident this carb may be usable sooner than later . one of the things in the list is the float weight of 12.5 G .... so i set it on a scale but soon saw its marked 12.5 on top of the float , my scale kept bouncing between 12 and 13 grams , close as this scale gets .

the only part that isn't JIVEING is the jet pilot air bleed , mine is marked 1.0 and its supposed to be 1.2 not sure what this means , 1.0 to 1.2 sounds like a small file could do that , open it up but im likely to just leave it as it for now . and ask questions rather than mess it up


and NOW if you look real close even the float has one of the " Rokal " logo stamps in the top of it .

[my3bugs]

i rebuilt this carb maybe a year back now but i didnt have any of this valuable information folks have shared here .... i keep going back over what i had done and now im questioning the needle n seat that came in the rebuild kit . its just generic no markings on it . the parts list shows i should have a Solex 1.2 or 1.5

well the one i replaced is a Solex 1.5 . would this needle n seat still be good here to use ? or go with the replacment or can i actually find a NEW Solex 1.5 needle n seat today ???

i sure like seeing it marked solex .
