Re: indy 500 help
Madmax, are your floats adjusted correctly, and did you change your needle and seats when you went through your carbs? it sounds to me like a typical loading up problem. Fuel gets it the bottom of the crank, and it will be a bear to start, it will pull over fine, just won't fire. Under this condition, when you pull the plugs they would be damp or wet (not neccisarily soaked), and when you put them back in, it will kind of sputters the first pull or two, but still won't start Next time this happens, pull the plugs, tilt the sled on its side. and with the hood open, give it a couple pulls. If gas comes shooting out of either cylinder, the bottom of your case has loaded up with fuel. if thats the case, it's either needle and seats need replaced, or the float level is off.
The other situation which isn't all that fun is that you may have a crank case leak. You might check your drain plug in the bottom of the case to make sure it's tight, or when it was put back together, whoever did it may not have got all the surfaces clean, and/or didn't get enouph crank case sealant all the way around the surfaces, creating the same problem as a leaky seal. One way to check that is to spray starting fluid (or some prefer Propane) around the crank case seam, and seals while it is running, and see if your rpm's change, or see if it runs eratically. When you refer to it being hard to start when it's hot, it makes me lean more to a crank case leak, but always start with the easy stuff first(carbs). The other thing it could possibly be is coils, giving it a spark, just a weak one. But if that were the case it generally wouldn't run well at any time.
ps You hear anything back on availability?
