You gotta know your machine

The '41 9N and I have been together for 26 years. I do the routine maintenance, tune ups, oil changes, grease jobs, and can change out bolt on parts but am not qualified to tear them apart but it's been running really good for several years or more. Tonight went to cut the grass and it made it 3/4 the way around and started sputtering and died. I let it sit a couple of minutes and it started right back up but did the same thing and finally quit for good on the front lawn. It felt and sounded like fuel starvation to me so I began the tests to eliminate things.

Checked spark, good hot spark, check. Clean and dry plugs which meant no gas getting to them, check. Cleaned the bowl screen and it was filthy and but good flow out of bowl, check. Cleaned the elbow at the carb and it was pretty clean and good flow, check. Opened the bowl drain plug and no flow to speak of which indicated to me the fuel wasn't getting through the carb. I took it off and tore it apart. Float looked good and worked with blowing through the inlet. Hit the body with carb cleaner until I got good spray through the orfices. Sprayed them backwards too. Bolted the carb back on and it fired up immediately and ran hard and I was able to cut the lawn tonight.

That was a new one on me but it worked out. You gotta know your machine.
 
Redogge,

I've read what you did twice and I still can't figure out what you meant by "a new one on me". (?)

I'm dying to know. :)
 
Sorry, can't edit . . .

nearest I can figure is clogged passage ways, "filthy bowl screen"
or both . . . you had never encountered before. (?) :)
 
My 8N does that sometimes. I think the float/needle seat gets stuck. If no flow out bottom plug, I tap on the body with a small hammer and it starts flowing again. Prolly rebuild it someday.
