I have a float that sinks, it has a series of small hard to see fatigue cracks from barometric pressure cycles, what resin will work in a gas/alcohol environment. to seal them up.
I can and will solder it but it is heaver than gas so i would like to use a substance that is as heavy or liter that gas,

Epoxy resin will work, but just save yourself the trouble and solder it.
The minute weight of the solder will make no difference.

I have used a gas tank repair putty before. You must make sure to clean it good then rough it up with sand paper, and use as little putty as possible. Your best bet is to solder it though.

DX Agree with he and those above. Most epoxy type materials are 'gas resistant' not 'gas proof'. Copper..Brass and Tin floats have been soldered since the beginning of the internal combustion engines birth. A tried and true fix..  |

There are different types of epoxy.
There is epoxy that you can repair your engine block with.
JB Weld should hold up under gasoline, and you can find it in stores.
Check online for different epoxies, but don't get any kind that is quick set.
Quick set = less strong and less adhesive.
Or just solder it.

Check online for different epoxies, but don't get any kind that is quick set. Quick set = less strong and less adhesive. Or just solder it. Agree JB WEld should hold... as long as the fuel doesn't creep under it. I just never had any luck with it on engines. Tried it twice on 2 scooter engine blocks. It was fine until the engine heated up and then the oil seeped under it and leaked again. Area repaired must be super clean and probably scrubbed down with a solvent....which was probably my problem. So I don't mess with it...to frustrating to watch it slough off the engine block like an old scab...  Also agree Quick set epoxy is less strong..less adhesive. I build RC airplanes and tried it a few times. Doesn't stick as well..and the Nitromethane/Methanol fuel soaks it..and it peeled off. Plus even without exposure to fuel..after about a year the Quick set stuff softens up and peeled of like a piece of used chewing gum.  Metal floats have been soldered since their invention.That is how they are made...so I just stick with that method. Call me old fashion.. ;D |

I soldered it. 40/60 I can't tell if it will be successful until time passes. I ordered a Chinese carb to replace it so I have a back door solution.
I need to figure out where to find a really small wire to open the idle jet. She is stopped up. Sugar in the tank deal.

We guitar players use a piece of 'High E' guitar string. It comes in .08 .09 .010 and .011. I keep a 6" piece in my toolbox for cleaning pilot jets. Almost any other wire is too thick to fit that tiny orifice. |

The replacement floats are only a few bucks and a cheap fix. Scrappy can get them to you in a few days via USPS.
Steel wire in a brass jet is never a good idea unless you were running lean before. A day in carbeurator dip (Berryman's) and a puff of compressed air will usually take care of it with no damage.
Probalby have to be a high E string from a set of Light Guitar strings. I use Heavy Phosphor Bronze and they are too thick for some jets.
