I got my old B out that i restored about 4 years ago. I have not cranked it in almost a year. The points were fouled, so no fire. Got. That corrected and it fired right up. Idles good and runs midrange ok, but it goes dead at full throttle. Is my carb plugged up?
 
Might be just a coating of varnish on the load needle. Before I adopted empty gas tank and empty carb shut downs for easy running next year I used to have to open each needle a turn and then place them back where they were. Amazing how just a simple thing like that makes them work for you well enough that the new gas flow will dissolve the varnish away in no time at all. But then I also had to do some minor tweaking of one or the other needle it seemed, until I adopted the zero fuel approach where I never need to tweak anything - she runs perfect always, just like I left her last year.

I shut the fuel off and run the carb out with choke to get the very last of it. Then I come back and siphon out the tank and burn that gas up in the car which gets fresh gas on a regular schedule. I have zero problems with rotten stinking gasoline.
 
I use my two-banger year round, but less in winter. I have made it a habit to always shut it off by fuel starvation before turning off the ignition. I also use a bit of Marvel Mystery oil in the gas all year long as it was developed for keeping Marvel carbs clean in the 30's. And it is a Marvel-Scheibler carb after all. I also use Stabil in the winter to try to keep the gas fresh. I don't know if either helps or not, but the beast always starts, so I'm going to keep doing the "ritual".
 
I use Stabil and nonethanol gas, but i will try that. I had it running dang near perfect when i put it away.

That's a beautiful tractor. I tried stabil too and still had to tweak some. I'd rather do the extra work of clearing all the gas out of it after the season is done because that's the end of all the hassles. Time spent with my tractor is the time I don't mind spending.

Hey Lee, I'm curious how do you keep the gas tank from rusting up over the winter?

Thanks
 
Take out the load needle and using an air blower on your air compressor line, blow down into where needle screws in with high pressure air. Load circuit hardly ever plugs up but may have skinned over or powder deposits. Assuming it worked before, the air should fix it.
 
I don't do a single thing about that, it appears to be a concern as non-existent as the communist under the bed. There simply is no condensation inside my empty gas tank winter or summer that I can detect. Always dry as a bone. The overhead supply tank is never full unless the delivery guy has just left, all year long it's the same story and not a drop of water to be found in there either. Horse feathers is what they used to say about a story like the full fuel tank is the only thing you can really do about condensation. I'd have to have some first is my common sense reply. As long as I don't have any, I'm tending to not worry much about it.
