Spark plug & fuel filter pictures, & another carb question

[simon0867]

Hello all,

Completed another bit of work on my TGB 202 Classic as I continue to tidy it up and hopefully improve it's running.

Following Saturdays carb cleaning session, I have now removed and replaced the spark plug.  The old one looked OK to me.  I read somewhere that a brown colour at the end was good, so I'm assuming this part of the bike is running well.  Put a new plug in anyway as I had one ready.  The old plug is pictured below:



Also removed the fuel filter, which I think you can see from the picture below must have been on the point of disintegration.  Replaced it with an identical model and also fitted a new length of tube from the filter to the carb (although all the existing tubes look OK to me).  Fuel did not start to run into the filter, I presume this happens when the engine is started



Finally a (hopefully last) carb question.  Near the bottom of the carb is a bit sticking out that looks like it should have a hose attached to it, but doesn't, and didn't when I removed it (see picture below).  Is this normal ??



Thanks as always for your thoughts, learning lots !

The bit and the bottom of the carb is the drain. There should be a screw pretty near too to open it up.

You can plug a hose to it, but since its closed all the time there is no point to it.

Thanks, that's a bit of a relief.

The color on the plug looks good and safe and if you have a vacuum fuel petcock it will not allow fuel to flow until the engine is cranked over as long as it's functioning properly.
