Question Time
would it be possible to modify a HC-E 1.3L 4cyl Dizzy using a CB60 Dizzy as parts, ie, vacuum advance module, theoretically giving a HC-E dizzy the required timing retarding for boosting like the CB60 has?
would it be that simple ( wishing 
)
Possible yes, distributor or vac advance boost retarded solenoid needs to be machined to fit

Can an earlier HC series dizzy with vac advance be used?

Yeah thats the one but the CB60 vac unit doesn’t fit in the early HC distributor housing, the measurements are out a few mm. You could drill it out if you feel keen but I would recommend paying someone with a lathe to do the job.

Am I crazy? Or does the g200 HC-E dizzy not fit into earlier HC-E heads. The g200 dizzy doesn’t seam to have a vacuum advance. I tried to put one into my g100 HC-E and it felt like it would not fit.
no you aren’t crazy, i looked while at the wreckers today and no vac advance module at all, on a 94 g200 hc-e 
looks like it’s back to the drawing board lolz
Early applause and G102 have the vac advance distributor.

I physically couldn’t insert the later model distributor into the older model head. Maybe it was keyed to only work with late model cam? I should investigate this further because it’s kinda odd. I thought all the heads and cams were mostly the same.

Measure the opening and the dizzy body first
