how to unfreeze carbs stuck from fuel.


I have tried every solvent on earth to free up a carb barrel frozen from storage. What free's up a carb barrel frozen from putting away a plane without somehow removing the caster oil left from the fuel drying up? I never expected not to fly it next week but somehow they are stored for longer than expected. then when it go through press flight there it is a frozen carb!!!!!!!!!! 2 cycle or 4 cycle they all freeze up. IS THERE A WAY TO FREE UP THE CARB WITHOUT DISASEMBLEING IT?

A heat gun works well, or a small propane torch works too so long as you don’t overheat it. If that doesn’t work, try putting it in the freezer for a few hours then hit it with the heat gun or torch.

If that doesn’t work, a cheapo ultrasonic cleaner from Harbor Freight with 50/50 water and Simple Green Pro HD works really well.

I would give it a shot of marvel mystery oil after heated up as mentioned.

get some fuel into it... it'll be free in an hour or so.
