Actually, it's kinda hard to find a "dumb" question, but "smart" answers are a dime a dozen.Excuse the dumb question...
When you guys are talking about carb problems from old "o-rings", are you talking about the ones internally in the carb, or the manifold sealing o-rings?
I understand my 1100E doesn't have the manifold o-rings... what are the symptoms you will experience when the "internal" o-rings are deteriorating?
Both sets of o-rings can cause problems. If the internal o-rings are leaking because they are cracked, the symptoms will vary based on which o-ring is causing the problems. Leaky o-rings at the inlet needle valve (float valve) will allow gas to bypass the valve and overflow the float bowl if the petcock does not fully shut off. Leaky o-rings around the enrichener valve ("choke") will lean out the 'choke' mixture, possilble making it harder to start. Leaky o-rings around the idle mixture adjust screw will wreak havoc with your idle mix settings, usually leaning it out. The other set of o-rings that will come in the kit from cycleorings.com will be for the fuel transfer tubes between the carbs. If they leak, they just drop raw gas on the back of the hot engine.
If your engine had the manifold o-rings, they would likely leak enough to lean out the mixture just before it goes into the engine, causing idle problems and overheating problems. You don't have those o-rings, but you should still make sure that your manifold tubes are pliable enough to seal well. Old tubes will harden and shrink, making it very hard to get them on and off, if necessary.
