I didn’t think I was supposed to have a recoil, because someone put a rope on it already. I had a feeling that the whole fuel system would need to be rebuilt. Is there anyone who makes the gasket kits or do I make those myself? Where do I find the impellers, points, and condensers? Just to confirm, this is a single cylinder, right?

It’s a twin-cylinder motor. Here’s one I did…paid $10 for it:

I know it sounds overwhelming, but these motors are easy to work on. I’m not a mechanic either, and the first motor I did was one just like this.

Also, what spark plugs should I use? Is there an autolite or other number? What are the points and plugs gapped to?

Ok, just got back from the store, and, I bought it. Its a Johnson HD-25, 2.5 horsepower. By most standards, I over paid, but Im happy with it. It has superb compression, though, so that makes me happy and comfortable with the price.
I think I am going to rename this thread either "1949 Johnson HD-25 Revitalization: A beginners perspective" or "1949 Johnson HD-25 Overhaul: A beginners perspective and guide for the total fool". When I get home from my vacation, the real fun will begin, with my trying to see whats wrong and how to fix it.
For now, James

I’ll give you a good helpful hint…….get a digital camera and take photos as you tear down the motor. I do this especially on lower units and anything I need to put back like I found it. I lay the parts out in the order I remove them and take a photo in case I forget. I also have several of those magnetic trays to keep little parts in so when I get in a rhythm taking things apart I don’t lose anything.

Ive heard this from many people, and plan on following the process exactly. I don’t have any magnetic trays, but I work on ford 8n’s (tractors) and when I change the points, I usually get a new distributor cover and use those for cups.
