When cleaning the passages out , just straight drill correct ? Saw old pictures of wires going through passages , can't get my wires to pass through the same way , or were there 4 wires used in example ? Sorry for the dumb question but want to rebuild it right . Thanks .
I will assume that the NH carb is the subject here.
If the photo below is what is referenced here, then essentially you are correct.
1. Approximately Perpendicular to the mounting face.
2. Angled towards the stem.
3. Angled towards the stem.
4. Perpendicular to the stem.
BE EXTREMELY CAREFUL TO NOT BREAK THE DRILL BIT INSIDE THE PASSAGE.
Thanks bob !! I've drilled them out with a No.36 bit , was confused by 1 and 3 , they both have blue on them so I was thinking they were one wire , lol!! Thank you again.
Yes, there are sharp angles inside, so no wire will go all the way through any passage. Uncle Stan recommends cleaning passages with a piece of brass-wound guitar string. It's hard enough to knock loose any dirt, and soft enough not to damage anything. Instead of plugging the holes with brass rod after cleaning, you can thread them with an 8-32 bottoming tap and plug them with set screws so there will be no drilling next time.
Thank you Mr. Jelf .
