Well, I thought it was fixed.
It started flooding again today. Not as bad as before I bent the tab on the carb, but still not good.
So I took both carbs off this time, and compared the float levels (which I should have done yesterday). The front one is much higher than where I set the rear one, but it is fine. I lowered the float slightly on the rear one, put them both back on, and now it floods only a little bit. It will start again, somewhat like seems to be your situation Neil, but only if I put the pedal to the floor to get a lot of air in there.
If I take of the hose to the hot start valve on the rear carb, gas pours out (dangerous, I know, because the exhaust manifold is right there), and therefore doesn't bubble up and flood the engine. On the other hand, If I leave the hose on the hot start valve and remove it from the venting filter, very little gas comes out.
first question, should there actually be gas coming out of that hot start valve? I thought it was just for vapour. If liquid gas in the line isn't a problem, could my problem be that the line from the rear carb to the filter is blocked?
Or...could it be that the rear carb is just getting far hotter than it should. Why does it get so hot when I shut off the engine? Is it heat from the exhaust manifold, or does it come from the intake manifold? If from the exhaust manifold, would a better heat shield help things?
