Two Problems: Leaking Carb & Clutch ON/OFF Issue. (Freeplay is correctly adjusted) - Page 2

For the gas foot, I don't think anyone has mentioned the gas line T-fittings? If they are plastic, they can crack and leak giving symptoms of a float issue. DAMHIK.

There's also the Brass tube, spigot, that is a press fit in the Aluminum carb body. These can work loose and be the devil of a problem to find the source of.

I guess any junction or line or part of the system that has Gas in it can leak.

Be sure to measure in from the center of the recess in the float bowl. I have a small file I've notched that I use for measuring tool.

Number one thing to check!
Number two would be gaskets. I suspect the carbs could use a freshening anyway.
If you need parts locally (not sure what part of LA you are) see Gaby in parts at Honda of Hollywood and provide her parts numbers, she will help you out. Do not get any work done there, they are monkeys, and not the cute kind.

Checked again today and the floats are old as hell. I did a slight spring bend modification to the right carb and so far she hasnt dripped. In any case I'll take her for a spin tomorrow around noon and hopefully find out if shes gotten any better.

In any case I decided to adjust the clutch by the BMW Tech day spec that was mentioned in this thread and found out something a bit wierd....

I used a 201mm (8 inches approximately) piece of straight coat hanger and no matter what i could not get the clutch arm and clutch cable end (at transmission side) to come close to this measurement. It was pretty far away from the end of the clutch cable bead.

Any idea why this is?

Another thing I noticed is that there was considerable up and down play on the clutch lever (which according to snowburn is not good). What needs to be done to remedy this issue as well?

Is this essentially an issue with the clutch cable just being old? If so I will go ahead and install a new clutch cable tomorrow evening I think.
