Hey Buddy, send me your e-mail or cell and I'll send you some photos. I've re-built those darn carbs many times and provided another member the same exact photos.... That choke linkage can be a REAL PAIN. the key ist that dinky little spring that bends if the wind blows too hard.... Let me know buddy. I have a 78K also and if you need any help... just ask
You're in the right place. There's also a member, flybox and harisuluv (re-builds these professionally) and they are a huge wealth of knowledge on getting these PD's nice and clean.
