Jcharro, why are we tossing them little bitty spiders back and forth at each other and shrieking in maniac mirth?

It all goes back to the fact that a slowly failing bad vac petcock can emulate a whole host of carburetor issues, fuel supply issues and even some spark related electrical issues.

So somebody joked that it wasn't really a vac petcock doing all the strange nonsense, that there was a spider in the bowl doing push ups over main jet (only thing that could do all the symptoms the guy was seeing).

Then the pic with our little buddy all curled up in the bottom of the float bowl showed up and it has been all downhill ever since.

Fact is, most of your troubleshooters won't even talk to you until you have gotten rid of that darned vacuum actuated trouble causer, mainly because until it is GONE you don't know what it is doing from what the carb might be doing.

And, in the majority of cases, the Raptor petcock makes all the symptoms stop as soon as it goes in place.

The rest of the time (like once or twice now) the remaining troubleshooting is quick, simple and straightforward because all the muddy water is gone.

So, get rid of your vac sucker and get then back to us once you've done so ....

if you have any issues afterwards that is.
