I have an HRR-216 2TDA mower that I am trying to get started for the first time after winter. It started once, ran for one path down the lawn then died. After that I tried in vein but I could not get the mower started.

Here's what I have tried so far. I replaced the spark plug and changed the oil, no start. I checked the fuel path, fuel is flowing from the tank into the carb. I pulled off the carb, replaced the gaskets, cleaned out the carb with carb cleaner and checked the pin and float, no problems there. I pulled off the flywheel and checked the key, no problems there. The tank was dry when I pulled it out of storage, but I used three month old gas I had gotten for my snow blower. No luck. I've drained the fuel completely and replaced it with fresh fuel, no luck. I've tried putting a little gas into the spark plug hole replacing the spark plug. When I try to turn it over it just backfires out of the carb.

I just bought this thing (used) last year and it worked great all year. I drained the fuel and stored it in my shed, although cold, still protected from the elements. I've called every Honda service center here in town and they all have backlogs of 30 to 60 days. Does anyone have any idea what my problem might be? Something that I might fix before my lawn requires a goat?

Thanks in advance for the help.

Probably a fuel supply problem. I'd bet some tiny jet or passageway deep in the carburetor is gunked up with slimly old fuel.

With a list price of $15.08, I'd just replace the entire carburetor and be done with it. Also put on new gaskets, and confirm you get them in the right positions and locations. Here's a parts list for your model:

The carb was working fine. The problem ended up being the spark plug. Although AutoZone told me the Bosch plug I bought was equivalent to the NGK plug listen in the owners manual, it did not work. I guess the gap was too large for that Bosch plug to fire in that engine. As soon as we closed the gap it started to work. That along with my uncertainty of the heat range had me replacing it with the original spark plug. I'll replace that when my local dealer has some in stock.

Thanks again.

First thing you do when you buy a plug is GAP it

(( racing is the only sport that you need two balls ))

I gapped it at the recommended .028 - .031. That didn't work with the Bosch plug, we had to GAP it at about .015 to get it to fire. That's why I replaced it with the old plug.
