Did you try to replace all o-rings on your Kayfuns, don't understand why they started to give you a hard time from middle of nowhere.
Yes, it was a good ride with them, but now I'm just done messing with them, in the last month, I have spent hours on them, and like the one last night, will work good for a few days and then start messing up again, I now got a squape, taifun and a fogger coming, so as long as 2 of them are good, then I will be set, that's all I need for work where I use tanks.
