In that case she should be a 12v (tank inside frame), does it have a round headlamp?PhilB wrote:She's an 82 if this helps.Diesel Dave wrote:C70 would use either a downdraft or sidedraft carb.....
Early big valve jobbies used the downdraft.
It could be a late registered 6v (tank separate and bolted to the frame by it's base), in which case it's the ZZ (key in the upper left side of the leg shields, has a 12v style exhaust originally and choke in the middle of the bars) The left side engine cover is a giveaway too as it has a small points access panel secured with 2 screws.
The reason I ask is; the round headlamp 12v C70C would have a reserve pipe and 2 tap connections whereas the square headlamp doesn't - you get a feel gauge instead.
Either way the chinkie chonk 90 carb will fit and it's probably closer jetted to use on a 70 so may work straight out of the box.
I can lend you one to try? if it works you can buy it, if it doesn't then send it back to me.
