Large Flojet Welch Plug Fix

Recommended Posts

John_in_Oxford

So, I'm mowing along today, and at some point, looked down at the carb, only to see the welch plug was gone.I know the "by-the-book" method - it failed. I know the RTV/epoxy/bailing wire tricks - but I wanted a more "serviceable" trick.It's called a "7/32x32 by 1-5/8" eye bolt. Daub a little bit of your favorite threadlocker/retaining compound on the threads, or hunt for a self-locking nut, or get real fancy-schmantzy and find a crown nut.Total outlay: $1.25, and that's for 2 - soz you can do your buddy's tractor and be a hero for 5 minutes!!!sm01

dOd Seems many share your plight...I've seen this install method on more than a handful of flojets. It works!

Hey John,

I was initially going to comment on this "mod" as thumbs down, but the more I looked at it the more my reasoning turned around to borderline brilliant. Going to various tractor/antique tractors shows over the last 45 years and seeing B&S large Flow-Jet carbs in various states with "rigged" Welch plug repairs, I think this one is a NASA class one. With a little Permatex #2 or other gas resistant sealer around the Welch cap edges and a Buna rubber washer underneath a locknut, I give this one now 2 thumbs up....sm01sm01

I bet even current/ex B&S engineers might approve.

Even tho they are more expensive and a thinner plug made to Briggs requirements, I set them with a golf ball and maybe finish the job with Seal-All. Never had a problem yet. Other Welch plugs are too thick, even the so called after market ones.

Thanks for the comps guys.

Welch plugs, along with the original Lone Ranger are native to my community.

I'm just not going to stress a` 40 year old, well worn carburetor - if its decided to spit the old one out, I'm willing to compromise.

BTW, if you want to read the "Correct Method, vis-a-vis the originators, go here(I have breakfast every morning about 200 ft from their front door:D):

EDIT: I guess I should throw in the "history bit":

I love the design. I would use a locking nut, either the crimped steel type or a nylon lock nut.

This makes it much easier to remove the plug to remove the screws if you need to fix a worn choke or throttle shaft.

you don;t have to have any thing to help hold them on. the ones that Iposted fit very.good and tight. but they easy to remove

they just push right in.

Didn't have the work you did.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
