Default magneto turns, no click?

I have a later model Fair Banks Morris, three HP. covered crankcase. I am doing a valve touch up, new gaskets and mounting blocks. A friend passed away and I now have it thanks to the years I shared with him, his daughter let me have
the engine. It has some minor fixable things. the biggest problem is the Mag. It does not engage or click to send spark.
My question is what is the best approach to fix it. send it in?
try a local repair? buy rebuilt? New? sure could use some advice.
Thanks much. Oh yes I have my Hercules running great. thanks again. Paul

Give us a model number off the tag. Think you may have misspelled the name, too. It may not have an impulse. A picture would also help.

Hi Paul,
If your engine is an FM Z style C it probably doesn't have an impulse magneto and you use a crank to spin it up to speed for starting.

I will get a picture of it in the morning. It is a type C and the mag is a Fairbanks Morris made. I took the cover off and the coils look like new, no age cracks, just clean and slick. I am no to swift on some things and did not know that some mags were impulse. It does start with a crank. does it have to turn a certain rpm to give spark?? I have the mag off so I will see if I can spin it at some point. thanks much. paul

Fairbanks Morse is the brand name of the magneto. Today there are some Morris Magnetos made for motorcycle racing engines not near the same thing.

You probably have a older FM-R1, FM-RV1, FM-J1 or FM-X1 mag. There were some that had a impulse made into the gear but I don't think yours is going to have that.

I want to thank all, for help that has been done to clear my mind on this. Here is some pictures to stop the guessing. The one of the points has a wire that does nothing and is bare. have no idea of what its doing or why. I do think if the points was cleaned and adjusted It may solve my spark problem. Now if knew the setting????? I think I will try about 18 or20 thousand. and see if that works. hopefully some will know the exact setting for this mag. Paul

Page 12 of RV service manual says .012" points setting. .012 to .015 or where you have the best blue hot spark. If got a yellowish orange spark replace the condenser. The K2433 is not available new but use a .22 mfd 600V capacitor or buy a rebuilt condenser from other mag parts vendors. They can sell you the capacitor too. New gaskets, cover gasket, brush & reproduction caps are available. Sometimes NOS points are available not sure I may have some but usually a filing will work on them. If rubbing block on points is worn bad replace the set or make your own block for them. 99.99% of the condensers in the RV are bad and leaking.

I am so lucky to be able to talk to all the helpers that have come forward to help me. it is not clear in my mind yet but I will study on it. In the last picture the bare wire showing, could that have been to the condenser??? IF not where is the condenser? can a vehicle condenser be used? The mechanics of an engine is nothing to understand but I am at a total loss when it comes to the mag part. I have replaced points and so forth in farm tractors over the years but they all wind up and release, new cond. and points and away you go.
So I am still scratching my head on this one. to those who know it is simple , I am trying to understand but its hard thanks Paul

Where that wire is you should have a insulated wire from the coil and one insulate wire from the condenser going to that terminal on points. The condenser if in there is a wide but thin flat metal one not round. Look in that parts sheet and will see the K2533 original condenser mounts under the top cover cap. Usually mounted with two screws. If you replace it with a capacitor like I mentioned you insulate one end to go to the points and other end is just grounded to the frame. Also notice the wire in parts sheet goes from coil terminal to the points. If it is missing just make one from insulated wire & ring terminal ends. Those will need to be there or replaced before you will get fire from it. A magneto makes it's own fire has a magnet in it so don't be hooking any battery voltage on it or will fry it. FM Fundamentals of Magnetos booklet is a good source to understand how magnetos work read it. Sent you a PM.
