@Darkbrador have you tried setting the float to allow more gas in to the bowl?

So basically the carburetor behaves like my bank account. It empties faster than it can replenish.

You could remedy that with less spending throttle, right? Why bother fixing it when you can work around the problems

"There was a local guy here with a 40 that had a similar problem. He had a small hole in the bladder of the fuel pump, and once it warmed up, it would leak, and fail to pump. Once his rig cooled back down, it would start and run again. If the sight glass is empty, you've ruled out the fuel filter, and you've checked the tank for obstructions, it sounds like the pump is the culprit to me."

@PowderHound the bowl empties really really fast, I don't believe the fuel level will change much. It's a legit parameter but the fuel pump replacement will come first.

@Darkbrador I had some similar issues with my 22r but replaced so much that it’s hard to pinpoint what it could have been. The spacer/gasket below the carb was one thing that seemed to help. Also did a new spacer on the mechanical fuel pump and new hoses when I replaced that

@Throwaway from 7-gallons per mile to approximately 11ish-miles per gallon?

That looks expensive ...

But think of the savings! As you drive literally dozens of miles a year!

@Darkbrador it's not the miles per gallon, it's the ease of use. You turn the key and start the car. The next time you get in it's the same process.

7 mpg to 11 mpg is an increase of 35%.

[Throwaway]

@theturbomrt one might actually be able to drive the fucking thing if it runs.

[Darkbrador]

@Throwaway 7 gallon per mile to 11 mile per gallon is actually a 7600% improvement.

There is no reason this thing can't run properly with a carb. It did for a long time. It will do it again soon ...

@Darkbrador Yeah it's not like they are hard to get to work, I was just offering up an alternative to 1885 technology that may be of interest. It won't happen again.
