my 350 rancher is a **** to start to in cold weather is that normal?,and another thing it ticks at start up for a few seconds and then goes away are the valves out of adjustment?
They're ALL different, but here's my general unscientific observation FWIW-
It should take a choke to start it, a machine in good condition still might like the choke for a cold start right up to 75 or 80 degrees. More than that is "fixable", less than that is pretty much par for the course.
Below fifty degrees, it's pretty normal to need the choke on, and to require a little throttle modulation to get it started and running for a few seconds, then have it sort its self out and idle fine.
Below thirty degrees, you prolly have to work with it for a few minutes before it's happy, and it's never truely happy until after you've been out and smacked on it for a while, preferrably after a short warm-up. This will "heat soak" the engine and then it should be a happy camper. They don't truely
warm up until you really ride them, so while it'll really appreciate a short warm-up, a long one is unneeded and pretty ineffective past a certain point.
Incidentally, if your winter is cold enough (and you're rugged enough) to require a winter jet, then this is the "threshold" I'd recommend for it where you'll start seeing some positive returns. If you don't ride that much in the winter (or at least when it's below freezing), then it's not a concern. For limited use you're good down to zero on the factory jet so long as you're watching out for an overheat.
A couple of things to watch for-
Regular unleaded gasoline!!!!! Regardless what the gas company calls it, the higher octane flavor does not atomise as easily, does not ignite as easily, and just does not lend it's self to cold weather as well. Assuming that "premium" or "super" means "better for my engine" is pretty much shooting yourself in the foot.
Learn what the machine likes. They're all a little different. Full choke and no throttle? Half choke and a touch of throttle? they all have a preference. The colder it gets, the less forgiving ANY carbureted engine is, and the harder it is to "pass" a flood and get it to run.
Don't assume that full choke is what it always want's. It may start better with your same routine and half of a choke. Flooding with too much fuel is harder to start than starving with too little. Or maybe not. Just be sure you're not fighting with it when you don't need to. Like I said before, see what your specific machine likes...
Key on, engine off (and all other electrical gizmos off) for thirty seconds, up to one minute before the first start attempt. There is a heating element in the carburetor to correct a completely different, unrelated, not even very likely issue with the carburetors. Allowing that tiny heater to run half a minute to a minute before startup has a good "side effect" of pre-warming the bowels of the carb. It's only just a little, but a little is all it takes to make a difference.
Below twenty degrees or so, hit the primer one time. (mayyyybee two.) don't over do it. It works or it doesn't. If that gets you a "start and stall", more pumps aren't better, give it the same one bump the next time. A couple of "start and stalls" and eventually it'll go.
And last, just as I said in my reply to outlanderrider... The rope starter...
Yeah, UGGGGH, it sounds like work. But, even if your battery isn't dead the rope starter still works. If you use the electric starter and it's hesitating or not trying at all, don't be afraid to give it a few good tugs. The extra cranking speed from the rope starter makes a HUGE difference in getting cold engines started.
As for the rattle for a few seconds.....
I can't say it's good, I can't say they all do it. It could be numerous things. But lots of those little 350's have done that exact same thing for a very, very long time with no further ill effects from it. But if you're in doubt about the valve adjustment, it probably needs it done. It's a good machine with a good engine, you should take care of it so that it'll continue to take care of you... but that "surgery" isn't going to fix a noise that dissapears that quickly.
