I just noticed on eBay what are called "cork flask rings". These are bonded cork of some kind and made for resting round bottom laboratory flasks on. You'd think they must be bonded with something resistant to solvents. Has anyone tried to make carb floats from these? |

Some friends have cut them from cork sanding blocks and then sealed with fuel tank sealer. Some have also used block Balsa with same sealer. |

I have made a new cork float from a round bottom beaker holder, I bought several beaker corks on E-BAY. The float is for my Krice carb on a Gray 3HP model "U". I then coated it with gas tank sealer figuring the sealer would prevent fuel from soaking into the cork. |

Thanks for the feedback. Given the ring shape a lot of roughing out work is already done, if the right size ring can be found, and they do come in a range of sizes. Old stock would probably be a better choice since the new ones are probably made somewhere where everything has the corners cut off! ;-) |

The Adams motor has a Monarch carb on it. Before I ran it, I took a look inside. After over 100 years, the cork float was pretty well shrivelled up, but the carb worked nonetheless.
I have big plans for the Gidley once I get it in the water this spring. A dodgey carb float might not be a good idea. I'd like to replace it. I was searching around today for a source of cork suitable to carve a new one. I came up with this.

What say you?
If I go with it, is it necessary to coat this float with a sealer? If so, what do you recommend?
Cheers! |

Put Paul Gray in the search function. Seems Paul is/was making replacement plastic floats for Schebler D carbs. Monarch carb pretty much a Schebler knock-off |

I had a look at synthetic floats. I then decided to try my hand at carving one out of cork. For cork, I bought a yoga brick. The brick cost less than a synthetic float. I found that with the tools I have available making a float was no problem at all. The yoga brick will yield enough cork for probably a dozen floats. To seal it I am using West System since I have it on hand. |

How is the weight with the brick material and the West coating? |

I purchased one of those cork Yoga bricks on Ebay a few years back to make engine floats with. It was a waste of money & time. I think the cork is more cardboard & rubber then cork. To heavy for a engine float. Reminded me of wood particle board but not hard.
The Nytrophyl floats work great are very light in weight and you don't have to worry with sealing the float. |

The shrivelled up original weighs 9 gr. The replacement, after two coats of West System weighs 11. The difference is negligible. Close enough for government work.

Take a look at corkstore.com Cork blocks for duck decoy carving. |

A guy in Gravenhurst, Ont, - mike Windsor, makes replacement floats for Scheblers using his CNC router that he normally uses for boat frames. He's a wooden boat repair guy - and knows about old marine engines.
http://windsorboatworks.com/
I suspect that if you give him your dimensions he can make up several of them.
I went the "carve your own" and "soak in Seal All" cork float route for the DisPro but eventually went over to the 21st Century material.

Chris, You must have got some different cork then what I got. The Yoga cork I got would hardly float and it was real easy to come apart into pieces.
Bruce, I think Paul Gray passed away or is this a different Paul Gray? |

My mistake, It was Paul Cox that passed away. Sorry for the misunderstanding. |

Bruce, The cork for the duck decoy's looks like it would be better as it is Low density where the yoga blocks are high density. Looks more like the cork used on the old style cork floats. A 9"x11-3/4"x4" block is $24.75 you could make many cork floats from that block.
Good deal, Thanks for the info. |

Earlier I wrote of making a carb float from a yoga block. The result was a float weighing within 2 gr of the original. It was easy, and I was very pleased with the result.
Elsewhere, people seemed to state that trying to make floats can be frustrating and ultimately unsuccessful.
I am now firmly in the latter camp. Despite my effort to seal the yoga block float, it absorbed fuel and doubled in weight. The result was a flooded crankcase.
Having conceded defeat, I am now in the hunt for a replacement. The Monarch carb appears to be a Shebler D knockoff.
Whereas information on this thread may have changed, can someone point me to a source of carb floats?
Cheers! |

Thanks Dick. You may be a life saver. My short term solution is to re-install the 104 year old float until the new one arrives.
Cheers! |

Yesterday I took the Gidley down to the river, and kept it captive on its trailer while I ran the motor with the 104 year old carb float.
That allowed me to make throttle, mixture and air valve adjustments. Once again it fired up right away, ran well and was easy to start hot or cold.
I have a few water leaks I can chase down but they are no big deal.
The river is in flood, and I have no chase boat. When I add it all up, the thing to do is to get a new carb float as I wait for more suitable water conditions.
Cheers! |
