Default 1919 Hercules 1 1/2 hp engine needs a magneto

Hello,
I recently bought this little Hercules engine at my late uncle's estate sale. I really would like to get it running. Thanks to some other folks on Smokestak I now know what kind of engine it is and that the empty bracket is where the magneto goes. This is my first engine and a real newbee at this sort of thing spam looking for information on what kind of magneto I need.

A 1 1/2 hp Hercules takes a Webster M if it has the original bracket. There was another bracket made later that would take a Webster K.

Thank you very much for the help! The bracket has 4 holes and is right next to the igniter. Does this look like original bracket?

I believe she's original.

Thank you very much. I see there are some "reconditioned" ones on eBay. Any suggestions of a reliable dealer to check with?

If the bracket is marked A303M it takes an "M" Webster. If the bracket is marked A303K30 it will have a larger bolt pattern (2"X 2") and take a "K" Webster.

You really want to buy a good working magneto. So if you buy an eBay item make sure its in working condition. With good magnet attraction.
Don't be price hungry as you might not be getting a bargain based on price.

I got the magneto but I seem to need another part that goes on the end of that square push rod. Now it pushes on the magneto "lever" (sorry I don't know the right terminology) but it rides up over the top instead of making a good connection with it to give a strong "crank" on the magneto to generate a good spark. Any further guidance would be appreciated!

There is nothing missing missing on the end of the trip rod. It just needs to be adjusted to make it work. You should grind the end of the trip rod so that it is square and has sharp corners, any rounded corners will prevent proper operation. You should get a copy of an instruction manual for your engine from one of the vendors on this site. It will tell you how to set the magneto trip.

Here on Smokstak, Harry has some magneto information and there may be some info on the Websters.

Spark timing is set by adjusting the trip pawl. Wind-up should be in the neighborhood of 45 degrees or so.

One thing that is impirtant is to make sure there's about 0.015" clearance between the hammer on the mag and the anvil on the ignitor arm. This adjustment should be made with the magneto at rest.

Someone who has more experience with Websters should jump-in here and correct me if I'm wrong. It's been a while since I set-up a Webster.

I found a user instruction manual on herculesengines.com. It is for model 1914 - 1916 but the diagrams look pretty close. As I mentioned in an earlier post it didn't seem like the magneto trip finger was being pushed by the push rod, it would just slip over the top. After a lot of frustration, and looking at the diagrams in the manual, it looked like the trip finger was on upside down, with the longer part of the finger pointing up and the shorter, more angled part pointing down. So I took a chance and took the nuts off each end, and the brass plate on the one side so that I could pull the central shaft with its small half-moon keys out. I flipped it over and put it back together. Now when I turn the fly wheel the push rod catches on the short part of the finger and rotates the shaft, but only a little bit. I loosened the nut behind the wedge and the set screw on top so I could move it a bit farther from the magneto and re tightened it. Now when I turn the fly wheel the magneto shaft turns about 30 degrees.
I suppose I messed up the timing by doing that but before it didn't seem like the magneto ginger was "cocking" enough to do much in way of making a spark.

When the square end of the push rod trips the mag the crankshaft should be about 27 degrees before top dead center for ignition.

The Webster mag should wind up about 45 degrees before tripping. Make sure the mag mount and mag base are bare metal where they touch - a low tension set up needs to bare and clean.
