Hello everyone,
I recently got my hands on the old cx500 custom 1980 that I used to ride when I was in high school. My sister had it at her place for about 6 years and it hasn't run in almost 3 years. Before they put the bike away it ran perfectly. The carbs had been cleaned, the clutch plates were changed, the antifreeze was flushed and refilled, the spark plugs were changed and maybe more. The spark plus have spark, the motor turns, and the electrical system seems fine.
I just finished cleaning the rust out of the gas tank and we wanted to try and start it up but the gas wouldn't flow to the engine(we checked the spark plugs for deposits). The petcock is open, the fuel line and filter aren't clogged, there are no bubbles in the fuel line and we didn't want to risk taking out the carbs since we are beginners and I don't have a shop manual.
I really want to get this bike running, does anyone have a good idea what might be wrong?
P.s. The fuel filter was clean before we de-rusted the tank and still is so I don't think rust got through.
Thanks
Update:
I confirmed that gas gets into the float bowl and there isn't a problem with the gas tank.
I took the carbs off the bike and i noticed that a little switch in the back of the carb seems like it wants to open the throttle slightly when i try to turn on the bike but it doesn't reach.
Also could having the idle set too low cause this problem? I don't know if it was since my stepfather messed with it as soon as i took the carbs off.
From what i understand the float must be working otherwise no gas would get to the float chamber. So the next step to check would be clogged jets? I think that's the last thing that could block the gas apart from not getting any air through the carb?
