You need to check because "usually" when the exhaust is full it is because of a petcock not closing and a dirty float valve not sealing.

If the valves happen to be open on the cylinder with the leaky carb, then the fuel fills the cylinder and then out into the exhaust system.

Check the fuel level in your tank, if you know how much you did have in it.

Smell your oil and exhaust.

If you smell gas, or the tank is empty, then service your petcock.

After that pull the carbs and remove the float valves (#23 Honda, ATV Parts, Scooter Parts, Motorcycle Parts,CRF,CR,MX Parts, Goldwing parts) and clean the valve seat and check the valve itself for damage and replace if necessary.

Then change your oil and filter.

 

Oh and that could cause the hard starting.... I got you. I just filled up so it should be easy to tell.

 

Is there a trouble shooting procedure I can do before I take **** apart to make sure it the petcock? I read on another thread here to look at the petcock while in the tank and see what position the switch is at?

 

That was referring to the manual shut off valve.

When you remove the tank, the first step before you remove the fuel lines, is to manually close the petcock.

To do this turn the square head (8mm or 5\16 if you don't have a 8mm open wrench) on the back of the petcock. I don't remember which way off the top of my head but it should only turn one way.

After closing the petcock, remove all the lines. Then, in a safe location, open the manual shut off valve on the petcock. If fuel comes out, time for a rebuild.

If fuel doesn't come out, hook up a line on the petcock vacuum fitting. Then with a mity vac (or by just sucking on the line) apply vacuum to the petcock. Fuel should now flow. Release the vacuum and the flow should stop. If it doesn't then rebuild the petcock.

Also when you check the float valves also check the floats. A damaged float could also keep the float valve from closing.

 

Cool thanks. I appreciate the help. Check in later with results

 

The only way asking for help will actually.....help, is if you do the steps laid out. If you are going to do your own thing anyway why waste time on the forum? There is alot of knowledge here that only works if you use it. We say flush & cap & you do a leakdown? How does that relate? Are you just trying random things?

 

ok, sir. i did a ******* flush and i did the cap. great now you know. does this change anything? nope not really. im just using this thread since i already started one instead of making another one. notice how this isnt a overheating problem now? something a little different? here ill make a new thread.
