Well, nothing to report. I had it running, tuned it slightly, then installed the muff mod and deflector. Started right up, tuned it slightly again. Left it outside (15-30* F) for the other night and yesterday. Got a tree down to the spar (thankfully this tree was in my yard) and grabbed the saw. Barely got it to start and slightly spool and acts like it isn't getting fuel. After that all I could get was a pop here and there.
So this happened last week and all I did was take apart the fuel system and check it for leaks, all passed and the tank vent checked out. So I put it back together and left it inside. I brought it outside and it started right up, 3rd pull, like I said before.
So could the cold honestly affect it negatively? I didn't like the fit o the manifold upon first assembly, just didn't seem to fill the space and it's important that it does to seal up to the carb so the impulse works. I'm gonna keep it inside tonight and try it tomorrow. If it starts I'll have to assume that the cold is shrinking the rubber more than it should.
I set the metering arm flush, replaced the gaskets with new aftermarket and replaced the metering spring. Which was a lot longer than the replacement.
