With choke on there is little if any change in idle speed, but it certainly enriches the fuel intake because I can smell it.
Yesterday it was almost like the choke was stuck on a little, you know that "holding back" kind of feeling. Is that possible?
Anyways, yes I think it's time to get the tank off and take off the carbs. These carbs are joined as one unit and need to be split?
Clean out bowls, floats, jets etc?
Not done this sort of thing in a long time. Last time was my old Ford with a twin webber carb way back in the 80s!!!
1. Take a ton of pictures
2. Take out vacuum cylinders from both carbs.
3. Take off bowls, remove floats and jets
4. Remove all hoses except the one going to the bridge between the carbs
5. Unscrew all the brackets and loosen the screws holding the bar between the chokes on each carb
6. Pull apart the two carbs... carefully
7. Remove the two bridges between the carbs
8. Take off the two covers for hoses on each carb (don’t know what’s this is called or does but there’s one on each carb on the outer side)
9. Remove idle screws (make sure to get the spring and rubber seat aswell)
10. Remove cable bracket
11. Remove the choke from each carb
12. Unscrew the disc on the butterfly on each carb
13. Rotate the butterflies to open and pull the disc out on each carb
14. Pull out the bracket for the disc on each carb
15 You should now be ready to soak your carbs... the forum recommends Berrymans Chemdip for 24 hrs each carb.
16. Id recommend also cleaning the accelerator pump (the weird looking thing on one of the bowls)
Chime in if I missed anything...
