My header broke on my O.S. 70 four stroke. I was wondering if i could use JB weld to temporarily repair it. I plan to order a new one tomorrow but will take a while to get the part. it broke completely off all the way around right where the threaded section starts and have the JB weld drying right now but was wondering if anyone has done this and how well it held up with all the vibrations from these small engines.

Thanks.
