So I finally got round to sorting the split coolant pipe on the mk1 that comes out of the rocker cover today. Job done, I think. As I was running it up to temp to make sure, fuel started gushing out of the overflow. Because it`s been a long while in storage, I thought it might just be a sticky float so gave the float bows a few taps but it`s still chucking it out. In an effort to see which carb it was, I disconnected the fuel line from the fuel pump and hung the aux tank up high to gravity feed the carbs as I didn`t fancy petrol pissing out right next to/onto a roasting hot exhaust. No fuel from overflows, so thinking that the tapping of the bowls had done the trick I put it all back together and fired it up again. Yep, you guessed it, pouring out again.
So my Q`s are, wouldn`t directly feeding the carbs by gravity simulate the problem, or am I being a numpty? and is there any possibility that the pump is over supplying?
I suppose I`ll be left with no option than to remove the carbs to clean and check the float needles, so is there anything that I should be aware of when the float bowls come off?
Also a quick electrical question. Unless the front brake lever is pushed right out the brake light either flickers or stays on. Is there any way of adjusting the disc that operates the front brake light switch in the master cylinder of is this to do with a weak spring and i'll need to rebuild the master cylinder?
