Title: Fuel in exhaust
Post by: Motorheaddad on August 07, 2014, 08:15:30 AM
Like the title states, I have fuel dripping from the exhaust. I just fixed a weak spark issue on cylinder 4 but now I have gas dripping from #4 where the primary meets the collector. From what I've read the issue would be that my float needle is being bypassed and flooding #4. I've already pulled the carbs to get ready to check #4. But, what do you guys think? And it's not condensation, it's gas. Anyway, thanks in advance.

I will be the first to chime in with "clean your carbs" and "order an RPM float needle O-ring kit"

I don't see a float needle O-ring kit on the site

Looks like he lists themwith a kit and not seperately

He has several types of kit and I suggest calling him to get exactly what you need.

Well now, to me.....that pilot jet looks out of place.

It was just doing a little exploring, but I helped it find it's way home. I'm assuming this would be my cause to flooding the cylinder?

+1 !!!  Steve, check your oil for gas and I would check the other 3 carbs and make sure the jets are clean snug while the carbs are out.  Good find.

Spot on George...

If you had so much fuel, as to drip out the exhaust, you can bet the farm that some fuel slipped past the rings and got into your crankcase...

I'm sure I have gas in the oil.. The worst part is that I just changed the oil last week with full synthetic yamalube!!! :dash2:

Don't fret! You can temporarily drain the oil, and perform a micro-fractional-distillation to recover the gasoline. Put the gas back in the tank and the oil back in the pan.

I just saw the trailer for the new Mad Max (remake of The Road Warrier), so I'm preparing for gas to be scarce in the future.

Took the carbs apart and checked to make sure EVERYTHING was secure. All good!!! She fires up and no fuel in the exhaust. Woohoo! Thanks again to all of you who helped. I love this place
