I've seen on here and heard from someone local about this "new trick" to make your sled start easier on cold mornings by choking it to stall.Now I'm no genious by any means but have had my share of wrenches in my hands so hopefully someone can answer this question I'm about to pose.If you choke the engine out does'nt that flush the cylinders down with gas?I understand that seems to be the point of this exercise to wash the heavy oil off the cylinders so it pulls over easier but if one washes the oil off how can that be a good thing?It would seem to me that doing this would inevitably cause something to wear out either rings or worse case cylinder lining,or am I being too paranoid?Having had to rebuild my SRX 3 times now from one failure or another,always resulting in replacing cylinders $$$$$$$$$!!!!!!!!!!!!,I would like some more input on this before I try using this method.Thanks.
 
When you flood the engine using the choke, there is still oil mixed with the gas. If you dont feel good about using this method of starting, then dont, your sled shouldnt be that hard to start anyways unless it is really, really cold. If that is the case, you could also have an explanation for your engine failures. (ie, the colder the air, the leaner the engine condition)
 
Your oil pump pumps oil into the fuel pump and then into the carbs. Thus when chocking the engine the gas / oil mixture will coat the cylinder walls for easy starting the next morning. The little bit of gas you put into the cylinders will mostly evaporate while the engine is still hot. hope this helps. Pat
 
You guys make some valid points that I never took into consideration about the gas/oil being allready mixed as it enters the engine.My sled is'nt really that hard to start anyway,its only when the temps really get down that she pulls over hard.Thanks for the insight.
 
There was an article in a recent SnowGoer about this. They were talking about doing this if its going to be really, really, really cold (-40*). The theory is that it washes the oil off of the cylinder walls so that in the morning you dont have as much cold, thick oil making it harder to pull your sled over. I dont know about you, but if its going to be -40*, the last thing I will be worried about is starting my sled. If its that cold, my butt will be parked into front of the fireplace all day long!
My 600 XC can be a bear to pull over, especially the first pull of the day, but its not THAT big of a deal. If its that hard to pull over, perhaps some of us need to either spend the summer lifting weights or put electric start on your sled.

its not that pullin it over is so hard, its the 30 fricken times you have to do it.
 
it's not that uncommon SRX. I work out of town and only get home on the weekends to ride. So far I have started her up in everything from -30 to +20. Let me tell you what I have learned. Unless you use some sort of trick (putting gas in the cylinders, choking out the night/last ride before), getting her started in below zero weather is some bitch. I'm not huge, so pulling it over at that temp. (from experience) has taken me a ton of pulls to get started. As for using the tricks above, I have found it makes a huge difference. Now as for the starting when it's 15/20 degrees out. Oh my god.....what a hell of a difference. Sled has sat for the last two weeks, got up there this weekend, no previous choke out, no gas in cylinders, 5 pulls on with full choke and she started right up. There really is still hope......
