Lepew Posted December 4, 2007 Report Posted December 4, 2007 What can running to rich do to a motor? I know it makes it run like crap, fouls plugs and causes global warming by releasing unburnt hydrocarbons , but what mechanical problems can it have. I seem to remember someone saying running to rich can make a engine run hot, if this is true, why? Quote
moneybags Posted December 4, 2007 Report Posted December 4, 2007 Running it lean will make it run hot. Or cause it to melt a hole in the pistion etc.ect. Quote
Screaming Yellow Zonker Posted December 4, 2007 Report Posted December 4, 2007 running rich will just hurt your performance. and fuel economy. and maybe your plugs. I would rather run rich than lean and burn out a piston. Quote
Lepew Posted December 5, 2007 Author Report Posted December 5, 2007 I found where I had seen the claim that too rich of jetting will cause overheating, it was in the Jetting FAQ section that use to be posted here at the HQ. Here is a cut and paste from it, Q#2:What happens when my Banshee isn't jetted properly? A#2:If the jetting is slightly lean or rich, the most you'll suffer is a loss of performance. However, if the jetting is way too lean or rich, your Banshee will overheat rapidly resulting in melted or seized pistons (which is the ultimate "bummer" for the 2-stroke motor). While overheating due to a rich condition is not common on Banshees (typically the plug will foul and not fire before it gets too hot), it's still not a good idea to run for extended periods with the jetting too rich. What "specific" damage can occur from this type of over heating? Specific means, if it is piston damage what kind and where on the piston? Quote
BenBB Posted December 5, 2007 Report Posted December 5, 2007 I never ran mine long enough to find out...a temp gauge is cheap insurance heh. Like moneybags and zonker said, running too lean for too long tends to result in a hole in the exhaust side of the piston top/front. Mine did overheat on me from being too rich (which could also be a function of going slow now that I think about it, since it would bog at WOT I couldn't get much air across the radiator so it couldn't cool, I dunno) but I didn't stay on it when it did, made it back to the truck and rejetted as soon as I could...
