So I have this pretty nice Husqvarna Tractor that was given to me. (Not sure if it is actually "nice" but since it was free, it feels nice to me)

It did not run when I received it in the fall. Covered it and pulled it out today to give it a once over. I was told it ran but then stopped and the owner got a new machine and bailed on it. It ran but not well according to the owner. He wasn't super forthcoming with the info but he was giving the machine to me for free so I took it. He brought it to a local shop and they worked on it but the problem persisted. I pulled it out today and took the carb off. The after fire solenoid is very stiff. Very difficult to depress and doesn't rebound well. Takes a good 5 seconds to respond. The needle tip was cocked and broke off when I applied pressure to it. So I'd started on the carb. Gaskets were compromised during disassembly.
So I was thinking I would need a kit and a solenoid. I saw that there were a few options for new carbs, about $115-150 for an OEM and then like 20 for an aftermarket based on the numbers. But the aftermarket wiring is a little different. This carb has a red wire connecting to the solenoid and a ground wire from the carb body to the block. The aftermarket carb has two wires coming from the selenoid, a red and a black. Being a newbie, I was guessing the black is the ground but wasn't sure.
I was hoping to find a gasket kit and maybe a selenoid for it and stick with existing carb but can't find those on the parts list. So my second thought was to go with the aftermarket carb, just to make sure it actually runs well. Then down the road, If it does well, maybe fork up the big bucks for the OEM after I verify it's a good machine. I'm confused by the slightly different wiring scheme with the aftermarket, and whether or not it will actually work. Any advice?
