Hello Forum, old member formerly known as Marz.



my bike didn't start up last week. this is only the second time this has happened. I took off the carb to drain it and spray in some starter fluid. after putting the carb back on there is gas leaking fron the little brass drain hole on the side.



Any Clues ?

The brass nipple above the carb bowls?

 

[eltontron]

yes, there are one on each side with a small hole

It sounds like you have two problems. One is that the float is sticking open. i.e. the float itself doesn't raise up the needle into the seat. Tapping the side of the carb may jar things enough to cure this. Use the handle of a screwdriver and tap on the bowl. Don't beat it, just firm taps.



The other issue is that your drain tubes are blocked somewhere. Either the tube inside the float bowl, the drain nipple on the bottom of the bowl, or the rubber tube itself. Take the tube off the nipple and open the drain screw. If gas flows out the nipple, then replace the rubber tube and see if it flows out the bottom of the bike. If it doesn't the rubber tube is blocked. If it does flow out, you will need to remove the bowl and clean out the tube and nipple.

Good Advice, a little tap did the trick. I should have checked this first. I'm not getting a spark from either side so I am troubleshooting this one by checking my starter and/or checking out the ignition coils, but would I still be getting a spark from one side ?

Can you explain ...how you are testing for a spark.where are you earthing the plugs/wires

 

[eltontron]

I pulled the wires and plugs and reconnected the plugs and am testing by hitting the start button and trying to get a spark on the engine head

 

[Blue Fox]

The "head", I assume you mean the valve cover, is not a good ground. It is isolated by thick rubber gaskets, and if it is grounded to the frame, it is by happenstance.

 

[eltontron]

so what would be a good place to check for a spark ?

i take the valve covers off and try on the block.you could take the tank off and ground to the frame[removing a bit of paint first]

 

[eltontron]

no spark,
