Been riding bikes for long time. To many in shed:) Joined to get info on repairing a bought new in 07 KLR. Carb being a problem with starting so removed and promptly dropped on cement and of course landed on low speed needle housing.:t1202: It toast now. Should have walked from project as just finished manifold replacement on Jeep and fingers looked like I tried play with a very mad cat. Spring fever. So now the quest for info of should I replace with used carb or new Mikuni. Any ideas?

Got out the JB Weld and will see if it will hold. The jet had something in it and that's clean now. Wont know if the epoxy will do the trick for 24 hours. Trying to see what the differences are between the 08 on and the older o7. Lot of newer carbs around fairly cheap

Haven't seen this with JB Weld but a combination "heads up" and request: I used epoxy to mount some screens to the fuel pickup tubes on our old garden tiller's Briggs & Stratton carb. This has worked well in the past with any brand of epoxy but this time the epoxy was destroyed by a year's sitting in alcohol regular gas. Anyone notice anything like this with newer gas?

Not all epoxy created equal. Some are made to be quick and without much strength. Rocket fuels are often bound together with epoxy. I used a bunch to make a non sparking paint to meet government specs.

I should have mentioned that I have used this same brand for the purpose for some years but....is it the same as in the past? Don't know... I have never had an issue with JB Weld or Devcon so, subject to more information, I will restrict my vehicle use to those two.

Another lesson is that gasoline will damage materials which withstand coolant, lubricating oils, but not gasoline. I've even been surprised by the difference between diesel and gasoline.

Is there a difference between the "common" jet fuels such as used in civilian helicopters and kerosene and varsol?

Alcohol is a solvent. Gas is not. Purity is the difference I believe in Jet fuel verse kerosene and of course temperature flow additives.

Its alive. The JB Weld Steel worked. Did two layers and let it setup. Sped up the process by hanging over the wood stove to heat it. Installed last night and started right it up. Still good this AM. Now hope the battery holds a charge decent or will have to order a new AGM:) This day is going good so far
