Ported one is on the left and manifold is on the right.
So I tried to change that, but the vacuum hose was to short and I had to buy a new one, which wasn't expensive and that was done. At first I've noticed that idle is little bit higher now, but engine seems to be responding much quicker and better. Second thing is that I noticed that air filter is quite dirty, which could also explain risen consumption also. But I thought that first I just drive around with the old one and see how that vacuum advance thing works out, but then again...
I have ordered new filter and I am about to put Kelly back to garage for the winter and there is still few hundred miles to drive before that and saving every drop is always better and you can drive for further.
