Ignition

What is the difference between ISO and FA ignitions?

[Bullfrog]

You've got me.

Maybe ISO stands for ignition struggles often, and FA stands for Failed Again?

ISO a measurement method for gaseous & fuel consumption. A measurement for gaseous emissions during inspection. ??

Also ISO is a setting on cameras as in ASA film speed. OK, ya got me too!

ISO is International Standards Organization.

FA is something else.

[taber hodaka]

So it would be the international standard measurement for gaseous emissions and fuel consumption during inspection tests.

OK, Lets get serious, these two ID,s are on two Diff. Hodaka Magneto,s. what is the info stamped for. Bruce

[Bullfrog]

Since there wasn't enough information for the original questioner to be more specific . . . AND there isn't enough information for the rest of us to offer anything but what you've seen . . . I'd submit that the responses have been (mostly) serious.

I am familiar with ISO as "International Standards Organization" and the photography reference which was mentioned.

Ok now I know what you are referencing Bruce. Hodaka was not to the ISO standards in the beginning. Later on they converted to ISO nuts, bolts, frame, carburetor ect. At the time it was a pain but long forgotten. Hope this helps-----------

Now the next question, do you have to match a ISO marked, magneto with an ISO marked, inner coils, point, condenser plate, or can they be mixed. Is there a relationship between the so marked items. Does one ISO item goe with only a ISO marked item. Hope you can answer. Also if the Magneto marked with an ISO can it be used for either two light and ign., coil plate or will it also work with the plates that have three of the coils on them or a plate with only one Ign., coil, and one blank connector. thanks guys, Bruce

That was my original question but some how it didn't get posted. Hope someone has the answer.

Bruce it is a nut and bolt item. The change was engine number 22486, the mag assembly went to ISO thread's so it is a nuts & bolts thing. As said 90 and early screws are different for the coils in the mag, condenser screw, felt lube pad screw, contact breaker screw and the backing screw's. the thread pitch is different. I nobody has ever had a problem there probably isn't one. I have on occasion. Hope this helps -----------Clarence PS It has nothing to do with the condenser it's self, per say

OK then . . . now I understand the question behind it all. The discussion brings out two issues.

1. You can't mix "two stator coil" system parts with "three stator coil" system parts. The early Hodies up through the B+ and the toaster tank Super Rat had "two coil" stators. Then the Wombat came along with the "three coil" stator system. These are different systems and mixing of parts shouldn't be done. Of course, just to keep the waters muddy - there are parts which are the same in both systems, like the felt and felt holder and the high tension coil under the tank.

2. The change to ISO (International Standards Organization) happened early in the "two coil" magneto system era - and, as already mentioned, was essentially a change in the standards of the fasteners. Like Clarence, I can't say for sure there aren't other factors which changed at the "ISO" change . . . but I don't think so. So, put the "ISO" item and the "FA" item side-by-side on the bench to check for differences before use.

The carburetor and pilot jets are also in this category. The ISO change was with engine P 22486 the early ace 100. The seat pan also went ISO. Clarence

Thank you gentlemen, I think we have answered the persons question from the first post. I know what happened and I know we all have done it. Over the years we have worked on many a Hodie, and filled a box of extra parts, but now all those many years go by and we dig the box of spares out to work on a project, and we have forgotten which item went with which item, to make a correct set, to use on the current project. The ol mind plays tricks on us all as we age. Now everything has been cleared up and we now can move forward. Again thank you for all the help, You guys are great. Bruce Young
