Both of the IDF 40 carbs had float ears that were broken, filed smooth, and then had the pin epoxied in place.
The epoxy was clearly not fuel safe, as the pin pulled free w/o any effort on my part. Is this salvageable? Could I keep the pin in with Quick Steel? My other option is scavenging the carb tops off my IDF 44s. Will they fit properly on the top of an IDF 40? I'd like not to do this, though, if possible. (IMG:http://farm3.static.flickr.com/2774/4156512236_14a9dc777a.jpg) Where could I buy another set of carb tops if I needed to. Ace? These carbs were a MESS. Lots of varnish, and lots of carbon. I bet they were lean on whatever engine they were on, and popping all the time. Zach |

Sure you could save it. Make a new piece, drill and tap the lower section and put a couple small screws in it to hold it back together. I wouldn't try to glue it. If you cant do it yourself, mail it to me and I can do it on a bridgeport tuesday nights.

Yuu should be able to get someone with a TIG to build that up, then file it into shape and re-drill it, but check with Art at ACE first. Most carbs that are lost to corrosion crap out the bowls, so he'll probably have an extra top around, and maybe cheaper than having someone TIG it.

Please PM me your address, costing, and time lines. I'd like to get this underway, so long as it is not more expensive then just buying a new top from ACE (who I'll be calling tomorrow for rebuild kits and venturis). Zach |

Trying to TIG weld potmetal is probably like trying to weld s*#t. It ain't gonna happen.

What about pinning it? Glue them back together and then use a drill press to drill two small holes that you could tap. Two small allen heads sunk in there should hold it.

I may have been unclear.
Its not in two parts. What I posted the pic of is all I have. The pin was epoxied directly to what was left of the ear. Both carbs are the same. As if the PO did it on purpose. I think I better just replace them. Zach |

Ah, I would make a piece of metal and place it over it with a screw. But I am ghetto at times, Dawg.

Looking closer, the the DAPO (not you Todd, I am sure you did not do this) actually CUT the ears like then, and broke them off at the bottom. And then glued the pin back in.
WTF! Seriously! This was INTENTIONAL! Zach |

I don't think so...
The slot is factory, and they just snap off right at the base... One broke when I squeezed it with pliers after I put the pin back in. The other broke while I was extracting the pin. Both looked just like that. |

I don't see the slot in the ones that Morph posted, and don't remember a slot in the 44s that I rebuilt - but that does not mean much.
The cut is a full 10 MM. Its supposed to be there? Why? Zach |

I figured it was slotted and broke off at the base. It really won't be a problem to fix in the shop. I'll machine a new piece, drill and tap the exsisting piece and viola your ready to go. The new piece will act like a clamp to hold the pin in. As per our PM, my price can't be beat. (IMG:style_emoticons/default/beer.gif)

The cut is a full 10 MM. Its supposed to be there? Why? The slot is there so the 2 sides of the ear can be squeezed together to hold the pin. I was trying to get the pin out of one of mine and I expanded the slot too far and snapped off one like yours. I thought about drilling through the 2 pieces and use a screw but the ear is too thin to drill a hole in it and not weaken it further. What I did was get a 00-80 screw about an inch long, bend it in a U to fit over both pieces and cut the head off. I got a very small piece of brass, drilled 2 holes in it to fit the U and held the piece on with the U, the brass, and 2 nuts. I used a pair of pliers to bugger up the threads a bit so the nuts will stay on. The stress on the ear and the pin that goes through it is minimal. JB Weld or any other petrol-impervious glue would work. |

miracle putty.
Or Get JB Weld that is fuel safe. Build up the area and drill out for the pin. If it was me, I would toss them and buy ones that are not broken. Rich |

Either buy the ones Morph has or send them to me Zach. I've done repairs like that before.
They are designed to have a slot with an undersized hole, so the pin is pinched to keep it in place. I doubt they were broken intentionally. Whatever you do, don't throw them away. If you buy replacements I'll be happy to take those off your hands. There is no reason to try and spread the two sides to remove the pin. It isn't that tight and should only require moderate pressure to push out of the slot. If you break it you are using the wrong technique - plain and simple. |

(IMG:style_emoticons/default/popcorn[1].gif) and I recommend replacing them with undamaged ones. Just for ..if nothing else, the piece of mind of knowing that the carburators are as original as possable, and you will never have "something else to check'' when adjusting the carbs, or setting the float heights. AND.....LOOK AT THE FLOAT PIN...look at where the pin is when installed in the top and how it sits BELOW the top of the main body of the carburator....LOOK AT THE LENGTH of the pin... it is UNNECESSARY / not REQUIRED/ not a WEBER design that the float shaft /pin is held tight in the "ears"......THE FLOAT PIN due to it,s LENGTH... will be stopped from excessive movement /or being dislodged /or from "falling out" ...by the side walls of the FLOAT BOAL...AND I think the photographs in a previous post, pointing out the "TAPERED" intakes...(top of carb cover)...these tapered tops were used in a slightly different application....They were for a 356 porsche , and had 28 mm venturis as produced by weber....the tapered intake tapered into the smaller 28mm ventures....(IMG:style_emoticons/default/popcorn[1].gif) |
