How do I keep it from Hydro-ing again?
« on: July 28, 2015, 04:42:26 AM »
I looked at my C10 this morning (proud that it's back together and running strong, thanks to you folks) but I had a tiny panic attack (not THAT bad but I couldn't find a better phrase)  WHAT IF I START HER AND IT HYDRO"S AGAIN???  I am a tiny bit scared that after it sits for a night it might have "done it" again?  It doesn't help that my garage smells like a gasoline spill (after all that major surgery)

What do you guys recommend I do to KEEP this (hydro-ing) from happening again? I looked for a "close-able" petcock (but that was before I even knew anything about the "vacuum activated" one thats on the bike.  I could not find a traditional / close-able one anywhere.  I've seen a guy (I think it's this site?) that put's overflow tubes in...nice idea but I like the close-able petcock idea better.

The main reason I like the ability to turn off the fuel is that it's the only way I know to "unstick" a stuck float while driving down the road!  It happens from time to time on my ZX11D...  this little trick works perfectly everytime.  When I hear a cylinder drop out because it's running way too rich (only starts to fire if I open the throttle wide open... something you want to do with caution on THAT bike...) I know at that point I have a stuck float... I just shut off the fuel and drive it till it empties the float bowls... ( that forces max movement of floats and seems to un-stick things)... turn the gas back on and keep right on going!

You could also pinch your petcock vacuum line with pliers to get the same result to empty the carbs while running.  Somewhere here is a thread about using a Pingle petcock and plate to replace the stock one.  A slight enlarging on the tanks hole is also required.

Steve (as in SISF - Steve in sunny Florida) is the one who diagnosed your off-timed cam gear.  His sight is:

I believe you can send just the carb bowls to him for overflow tubes.  He has a lot of other fun stuff too (order the jets too while you do this).

Visions of things going "BOOM" in my head :shoot: :shoot: :yikes: :shoot: :shoot:

Yes, pinching the vacuum line would work... But I can't imagine doing that AS I ride down the road haha!

The petcock you mentioned.... Where? Any links? Is that a brand? Or a model?

And yes it was Steve's site where I saw the overflow tubes.  Years ago I read about his jet kit too... I think I will do that,  I think I remember him talking about the fact that the c10 (if in perfect health even without his kit but certainly with?) can wheelie (first gear @ 4k ...slam throttle open). Mine has NEVER been able to do that!

This may have it (search is our friend).  I also realized it is Pingel and not Pingle.

Seriously, get the overflow tubes installed and keep the petcock maintained.
A manual petcock is only as good as your memory. Forget to shut it off once and if that's THE time a carb needle/seat chooses to leak, you're still in jeopardy.
Overflow tubes never forget.

Amen Jettawreck :chugbeer:  I'm sorry I DO NOT Trust those vacuum petcocks! If I could find an immaculate tank... I would MAYBE concider it... but it seems to me the tiniest piece of junk (from the old tank) can cause it to fail (even if it were brand spanking new)

no, not really

 I just know they have a lifespan. you cant expect a couple of o rings to last forever. and if you clean the carbs occasionally you check the float needle.

preventative maintenance   ;D

there's always manual petcocks. easy to get in the habit of turning on and off :)

Go to the lawnmower shop and get a Briggs & Stratton inline shutoff valve. About $5. Then USE IT.

Yeah and "inexpensive" too as long as it doesn't mess with flow... (and I see guys going on and on about venting, kinking, and filtering) but worth a try and a heck of alot easier to deal with then another bent con. rod  :hitfan:

Murphy has a very good manual petcock conversion kit designed to replace your old Connie killer petcock at a good price, $60.  http://www.murphskits.com/product_info.php?products_id=483  If it were me, I would send your float bowls to SISF ASAP to install overflow tubes, $80. This will be the best money you can ever spend to protect your Connie. HTH

The B&S flows plenty of fuel for a 1000cc engine. I still use em. And I use one on my home made workbench fuel tank.

SISF, How long (just curious) is the turn around on you doing both the overflow tubes and the (entry level) Jet kitting?  Can you tell me the cost too? (sorry if those are improper questions)

You would probably be better off emailing Steve directly.
