rototiller got wet, won't start

I have an old Sears "Roto Spader", which is a front-tine rototiller. It has a Briggs and Stratton 4HP engine (Model #100902, Type 0149-01). It has worked faithfully for me for more than 20 yrs, but I left it out and it got rained on. Now, if won't start. Gas is being delivered to the spark plug, but there is no spark going to the spark plug when I crank it. Suggestions on what the problem may be and how to fix it?

Check for spark with a new plug. I that doesn't help, it could either be at the points or the kill wire. Find the kill wire - it should be attached to something that moves with the throttle in kill position. Disconnect it at that point and see if you get spark. If still nothing, pull the flywheel and check the points. They may need a little filing or shaping up to get a spark through them.

Spark Plug Ok, check points next

I have verified that the spark plug is OK. Next, I will follow your suggesiton and pull the flywheel and check the points. In looking at drawings of this engine, and having used it many times, I'm not sure that this engine has a kill wire, but I will look for it. Thanks for the suggestions.

I found the kill wire, and pulled it off the throttle block - didn't seem to be the problem. Now, I am trying to find someone with a flywheel puller so I can remove it and check the points and condenser.

You really don't need a puller for those. Just put some firm pressure between the flywheel and crank case with a wedge of wood and tap the side of the flywheel with a hammer. They will usually pop off.

Pulling the flywheel

Thanks for the suggestion. I never have pulled one of these before nor have I seen it done. My son is coming up this weekend, so we will try to pull it and check out the stuff underneath.
