Oh and thanks for the SOS pad idea Scott. I'll give it a try!

Well, slight delay on the lift off from mission control. Dead battery and once I put a little bit of gas in the gas tank found out the cutoff valves leak. Nice. But no worries. Got new cutoff valves a while back just in case. Only thing, the one's on the bike now are not original. Didn't realize that until I grabbed the new ones.

So the new, original style, cutoffs are threaded at both ends. Obviously the filter end goes into the tank, but how do you attach the fuel line to the other threaded end? The cutoffs that are on there now that leak just had a nipple on the end that the fuel line slid over. I'm guessing there is some kind of compression fitting??

Probably 1/4" BSP fitting.

I like these right angled ones, because they allow the fuel line to have a nice radius.

Thanks Sam! I'll see if my local parts store has one. Otherwise I'll order online.

Is there any kind of thread tape on that connection to the tank? Seems like metal on metal might need some Teflon tape or something to keep it from leaking? No?

The teflon tape I used disintegrated pretty quickly, so I gave up on it.

For the tap to the tank, I use a doughty washer (copper with bonded black material inside) and Loctite 577 thread sealant. I think either would probably do. The operative word is probably. Fuel leak above hot motor, not a good thing. Ask me how I know.

For the tail to the tap, a touch of the same sealant seems to work for me.

Maybe your kickstart lever has some lateral movement on the shaft, and moving it in or out might make room for the cotter pin.

Cheers,
Neil.

If you're talking about the fitting from the petcock to the tubing (like the fitting Garioch posted), then no sealant is required. The fitting should be free of debri and corrosion. Your petcock has a concave end and the fitting is convex. Both brass (soft). The connection from tightening should be enough for no leaks.

Yeah I saw the compression style on that one. Was more referring to the one from the cutoff to the tank. Will try some thread sealant.

No luck at the local parts store. Guess its online shopping time.

The T140E had the 25 degree angled spigots. You can see them here:



Part number 82-3353

Thanks Scott. WOW that's a clean looking engine!!

So this weekend was full of disappointment. Got the fuel stems installed, filled her up with a little fuel and tried to kick her over. Well, no luck. Then I noticed the carbs dripping pretty steadily.

So I'm guessing the carbs need rebuilding, unless I flooded them, but they started dripping pretty quickly. Not sure even enough time to flood. Guessing the floats are stuck and prob shot?

Second issue, no spark. I searched a bit around the forum for this very common problem and I think I covered everything. Well, I got to step one and think I found the problem. The ignition coils are not getting power. I checked the ignition switch and was getting voltage.

Now I'm no pro on the meter but I should be getting voltage at the coils correct? I don't measure for resistance do I? I pulled the leads off each coil and put the meter leads on the leads that hook up to the coil and got nothing.

Unless I'm missing something there is no power getting to them.

Battery checks fine too. About 13v.

What's my next step?

I do have an interesting tid-bit of info. My neutral light isn't coming on anymore. I know I'm in neutral because I can obviously push the bike in and out of the garage. Could the system think I'm not in neutral so therefore not sending current to the coils?
