Greetings all,

I've got an '83 1500 Civic wagon with two problems:

First, I've done a complete tune up on the car and all vacuum lines seem to be fine.

I've adjusted the carb float levels and both are centered in the site glass with the engine idling.

So, it idles and runs perfectly. However, if I drive down the road, when I come to a stop, it is flooding out. When I look at the site windows, both bowls are completely full of fuel.

If I keep it running for about 20 seconds or so, the level slowly drops back down to where it should be and then it will idle fine...

I'm stumped! It's very frustrating because it constantly wants to stall out.

The second issue is an oil burning one. I've already replaced all valve seals with new viton and have also replaced the auxilary valve seals and o-rings. Valve guides had minimal wear (car has 130K on it).

If the car sits overnight, when I start it in the morning, I get a HUGE cloud of blue smoke. It will burn off then clean itself up...

So my question is this - has anyone ever had a situation where the head gasket leaked in the oil passage area that allowed the pressurized oil to the head to leak into a cylinder? This is the only other thing that I can think of.

Yes, it burns oil when running but not much so I doubt it's rings. Further, it clearly leaks oil into one or more cylinders after it's been sitting because the smoke is unreal...

I'm thinking I need a custom license plate that says INSCTFGR or something...

Again, I'm stumped on this...

Any help would be much appreciated!!!

Thanks,

Steve

i never tinkered around too much with the stock motor but i would say turn the floats back down if it's flooding out. as for the head gasket thing, the pressurised passages are far away from the cylinders and have a sleeve arround them however the return passage is right between 3 and 4 and does come fairley close. that is a possibility but it is just gravity that returns, no pressure.

Been a while...... still a solution needed ?

I Just joined. I have an 87 and there's no float glass but I would check the fuel pump pressure. If it is too high then your carb will flood. There is also a fuel return line to the tank and if it is blocked then the fuel cannot return, causing the pressure to build at the carb.

The apparent oil burning issue may be a flooding issue. Too much gas flooding into one or two cylinders will produce loads of black like soot out the exhaust when started. If the pump pressure or return lines are ok I would next check or replace the needle and seat in the carb ( or get a known good carb swapped in to compare).
