quick carb question
« on: 05 October 2019, 03:21:18 PM »
Just refurbed carbs..new mixture screws in a couple o rings etc, and now resetting the mixture screws to 2 1/2 turns (003 model)..after setting to 2 1/2


turns,  carb number 1  has no part of the screw showing in the mouth of the carb but 2,3,and 4(tps side carb)have about 1mm sticking through


Should they all be protruding above the rim of the mouth of each carb, or is it normal that carb 1 screw is flush with the mouth of the carb ?


cheers

Did the replacement come with seal washer and spring?If so check all the original bits came all out before installing the replacement.Would not be the first time a seal or washer was left in by mistake.
Depending on the quality of the new ones you could get the ends different sizes.
If you are sure nothing was left in, remove them all and check the lengths of the thin part are all the same.

pretty sure all seals and washers are out, but I'll take em apart and check the thin bit  :) :)

Deffo no doubling up with o rings /washers etc..swapped the mixture screws around and still no protrusion on carb 1 into mouth of carb no matter which


mixture screw I used


..got 14 thou guitar


 string (closest size to the height of other 3 screws.) and set carb 1 to that , so they are all roughly equal in the protrusion department !!


Hope it works now !!

Do you mean pilot screws?  These sit in front of the float bowl underneath?
