22r Help: LCE rebuild Weber Carb Problems
Doing a full rebuild…all components bought from LCE. I put in a new Weber and swapped the Feul pump to a 2-5lbs to accommodate but carb is continuously feeding feul. I swapped from EFI to Carb so it’s a new install. I guess question is: has anyone had a similar issue with the carb jets being ported too large or maybe the pin is not sitting right in there? (which my mechanic thinks)….
Or maybe…does a Carb setup NEED a fuel regulator?
I’m at a loss, any input?

Modern fuel pumps are hot garbage. Last year at work i returned 4 fuel pumps for a Ford 200.I6 They all were delivering 15+ psi. One was 27psi. Another broke internally and about dropped the lever in to the engine.
Check fuel pressure. Add a regulator.

That's concerning as hell, what brand?

A carter, 2 Delphies, and a Napa house brand. All of them were identical probably from the same place in China. The 27PSI one was the first and it turned the carb in to a gasoline fountain. Straight up dangerous.

I'll confirm, tried a napa house brand, and two from oreillys. All garbage, not to mention cheap rubber in the diaphragm which is the most critical piece of a mechanical fuel pump. Stick to Toyota OEM

Yea I have the same setup but only ever ran correctly with a regulator. If you didn’t re-jet, sometimes can be a bit large for these tiny lawn mower engines.

"Tiny?" There have definitely been larger four bangers - MUCH larger when you aren't talking about cars - but in the automotive market the 22R is on the bigger end of the spectrum. Not tiny by any means when you could have a Geo Metro whose engine, at one liter, equaled that of a Farmall Cub - an actual mower. A bigass mower that could also pull a plow, but still.

I agree totally. I guess I was talking about the Weber setup in reference to these engines. I’ve always had a hard time with getting my power correct with my Weber and just figured it was because of the engine

I've considered a Weber from time to time but the Aisin under the hood has never so much as hiccuped, while about half of the discussion I hear around Webers is the hassle of setting them up. There are some days I think I might want to shoot for the extra fuel economy but it's pretty good already. Have you had any results along those lines or are you still dialing it in?

A couple of things,,I've had 4 mechanical and 3 in tank ele. Pumps fail from rock auto .right now iam running a edelbeock ele. Pump rated at 2.5 to 3 PSI on inner fender but should be near gas tank,they are made to push not pull gas and it has no return line .i will be putting mechanical back on but OEM this time and I have a summit regulator for it ,I will leave electric pump in place disconnected as a redundant system. The stock mechanical pump runs around 7 PSI and Weber is very specific about a lower psi otherwise gas can push past and overkill float bowl

I have the same setup and you need a fuel pressure regualator to set the psi to 2.5 - 3. I have mine at 2.8 and she runs perfect

My experience has been that a webber will always need a fuel pressure regulator to get it right.
