I completely disassembled a 194t and had to swap it all to a 192 case because bar mount stud was stripped. It worked with a little bit of fabricating and the saw will run. I’m having trouble figuring out the impulse line and the fuel tank return. I’ve searched for videos or diagrams but with no luck. When I disassembled the saw I had another 194 and was gonna use it for a reference, but I traded it to a like new 346xp. Any help, videos, diagrams would be greatly appreciated
