Hi Young, here are some pics of my TAC 80 so you can see, hopefully, where everything goes:
[Linked Image from i266.photobucket.com] Fuel Line to front of carby.
[Linked Image from i266.photobucket.com] Decompressor to rear carby body where you had the white broken bit.
[Linked Image from i266.photobucket.com] From under the engine cowling to side of carby.
[Linked Image from i266.photobucket.com]Eyelet to under first cowling bolt.
I have decided to remove my cowling and take these pics so you can see exactly where they go, so there is no confusion.
[Linked Image from i266.photobucket.com] Decompressor to where your broken tubing was.
[Linked Image from i266.photobucket.com] Vacuum tube from its attachment on cowling to side of carby
I hope these pics are of help. wink
cheers2
