Plenty of spark with both plugs(I keep a spare) Gas tank is above the engine. So I should be able to get a gas/out petcock with a shutoff and no vacuum line from ace, yes? Meanwhile I killed my dang battery. just get a piece of fuel line, and run it from the tank nipple straight to the fuel filter. That will take the petcock out of the equation. Also make sure fuel is flowing thru the fuel filter in the correct direction. There should be an arrow on the filter that indicates the direction the fuel should flow. Mine goes tank>filter>petcock>carb. So make it go straight to carb from filter? |

yeah. And then plug the vacuum line that goes to the petcock.

That means we have ruled out the petcock. From there we put the petcock back in line and then do the same to the filter. With those two things ruled out, we can move on. then we will start checking for vacuum leaks.

ok... now we need a bottle windex, soapy water, carb cleaer, wd-40 or what ever.
Start the bike and listen to it. Spray around the where the carb meets the manifold and listen to it. Did the idle change? Do the same where the intake manifold meets the head. Spray it anywhere there is a vacuum line where it goes into a fitting.
What the liquid does, is plug the hole momentarily. That will tell you were a vacuum leak is, if you have one. Check for cracks on the intake manifold... they are notorious for cracking. Use the same method.

Can't get it to run ATM, may go from .005 to .004/.003 and see if it does anything different. The valves were way tight it seemed when I adjusted them. I will say I was coating a lot in carb cleaner earlier looking for vacuum leaks and no change in idle. |

ok... readjust the valves....
will it run if you spray carb cleaner in the carb throat while hitting the starter?

Yeah, down the carb, take off the intake and spray a couple of quick blasts down the intake of the carb. See if it sputters. If it does then it's a fuel or compression problem (you will know it has spark at least)

Got it running and driving around the block after idle and air screw playing. But I had that before we will see tomorrow |

To follow up, had a buddy come out and give me an extra set of hands while I messed around with it. Seeing how it was warm from trying, trying, and trying again. However I gave it for a pretty good while and seemed to be doing well. If it startsnup and runs well tomorrow I will know exactly what was wrong. Valves, idle, air/gas, gas lines(they were deteriorating), and the petcock had some crap in it.
Will keep y'all posted if the problem is fixed. Talk to y'all in the AM!

Success.. Rode it about 50 miles today. Stopping at various places for different amount of time (food, visiting a friend, checking schedule at work, small errands) and haven't had any problems! Fires up usually first, sometimes second lick. Smells a little rich but running great.
Thanks for all the help guys. If you're in SE TN give me a hollar for a ride!

That's great! Better to run a touch rich then lean... that's for sure.
