78 1000 carb leaking past the bowl gasket

[Guest]

My 78 1000 carbs are overflowing past the bowl gasket on #3 carb(or is it 2?),the rest are fine.Float and level are good so I guessing the needle and seat are DOA.Anything else that would cause it?
Edit:An OEM one's $32 USD.That's crazy!Z1 has one for 5 but shipping is more than the price

Standing or running? If standing then your Petcock is leaking & the needle/ seat might actually be ok just overwhelmed. I had a similar thing on the 78 at one point.

Don't have the tank hooked up yet,leaking if it's running to but it's all on the auxiliary fuel source.

Great,Z1 only has only 1 seat and needle in stock and I figure I might as well get 4.Thinking if I only do 1 the next weakest will start leaking.Parts N' More has them to in the KZ900 listing,more $$ but they got them in stock

Tap on the bowl to see if you can get the needle to seat in the seat.

I'll try that but I don't think it will work

Be sure its lot leaking at a fuel joint and just running down the bowl and you think its the gasket.

New aluminum T and crossovers Chuck,they lessened the leaking but it's still leaking out of the gasket on 3 and the overflow on 4.Just doing the needles and seats on all 4.

Over flow running is a symptom of incorrect float hts or a stuck open float needle.

How high up is your aux fuel source? Unless it's shallow & right on the seat you could be applying more pressure than you think. I am pushing you down this route because it is the one closest to the fuel hose....

You could try dressing the end of the needle with fine wet n dry. Also check that the spring in the end of it is not shot.

The wife has decreed I'm getting new ones so I am.Seems like a wise investment for peace of mind to.Don't have a long line on the aux fuel source but I guess it could do what you're thinking Salty but I'm just not sure about these and we just ordered new ones from the local dealer.Thinking about it now I will try that dressing idea and see if that works.

OK all new needles and seats and a few days of poor running because some dumb ass didn't check exactly how the coil wire are set upFixed the coil problem and out of the blue #4 is p*%%*&g out gas.Yes I hit it to reseat the needle,still the gas pours out till I turn off the petcock

Float Dragging on the gasket is all I can think of. If they are canted even a little theres a chance they can snag up. I always eyeball them to be as straight up and down as possible,before i set the float hys.

As quick as it started it stopped so maybe something got caught between the seat and the needle?Idling WAY to high(1800 RPM)so it looks like I need to adjust the side heights.
