Just picked up an 87 gl wagon, 1.8 carbureted, for $200! Was running, but running rough. Rather unknown history. Passed emmissions with flying colors!
Replaced air filter, oil change, spark plugs, spark wires, dist cap, drive belts, radiator hoses, water pump bypass hose, timing belts, oil pump, carb accel pump, float needle, carb to intake manifold gasket, and a few vacuum hoses. Tried to start, nothing, sounded weird...Couldn't figure why it wouldn't, so I tried cranking it A LOT (oops.)
Called a soobie mech, told me the chiltons i was using had the wrong timing belt replace procedure (they called for both cam marks to be up), so i set the passenger side cam 180 off (down), made sure the drivers side cam mark was up, and the crank on the 3 timing marks. tried to start, still nothing, though it didn't sound weird anymore. Smelled a lot of gas! Once again i cranked it a lot, not knowing...
Pulled off the airbox to check carb, noticed it was pouring a lot of gas out of a tube on the chamber towards the front of the car. Thought maybe the float chamber was flooding, and the ton of excess gas was flooding out the cylinders. Realized that I had been cranking the engine a lot and so a lot of gas had been entering the cylinders. Re-checked the float measurements per the instructions in the rebuild kit. Checked the float needle, realized the one I had just replaced was different than the old one, so I put the old one back in, since it looked pretty good. Had a friend over, who said he had never seen the tab on the float sit in between the small metal clip and the needle. We put it above the metal clip. Engine started up, revved really high, poured LOTS of white smoke out the exhaust, then died. Wouldn't start again, though it would sputter a bit if pumping accelerator.
Didn't know if somehow I had blown a head gasket when I put the timing belts on backwards (due to chiltons procedure), so drained the oil. No coolant, it seems, but really gassy. Decided maybe the gas I had been pouring into the cylinders (because of the carb)had broken the seal on the rings, and gas had gotten into the crankcase. Replaced oil and filter, still no start at all.
Took carb back apart, no gas in float chamber. Put float tab back between clip and needle as it was originally. Car started up, revved high, still blew white smoke out exhaust, but less...then died within a rew seconds. Noticed gas was pouring out of overflow(?) tube again.
SOOO. Am thinking with the carb float tab above the clip, it doesn't get gas (the float chamber being empty), with it in between the tab and needle, it floods (the gas pouring out that tube). Does that make sense? And that the smoke out the exhaust might be built up fuel in the cat, or exhaust?
Does anyone know where the tab should sit (in between clip and needle?), what the adjustments should be for the float, and why it's flooding out?
Or might it be something else?
Am kinda lost at this point...Thanks!
