Zero power. No miss. Fuel. Spark. What ck next?

[85glsw]

EA82 '85 GL SW, 1.8, (Hitachi?) carburator (rebuilt or not the orig.).

 

No power at all. Can't even get up a steep hill in first.

 

Cylinders don't miss. Idles fine.

 

Has fuel. (Lots of it.)

 

Has spark on all four cylinders.

 

Don't think there are any vacuum leaks.

 

Starts and idles fine.

 

Both sets of cylinders sound the same.

 

When it was really cold, there was dark smoke coming out the tailpipe. Now no smoke. (No thermostat.)

 

No coolant loss.

 

Oil's fine.

 

Tailpipe full of carbon, but dry.

 

Yesterday when I shut it off, it had been running fine.

 

Been intermittently having this problem to a much, much lesser extent from time to time for a few weeks, but I would rev the motor or plug up a vacuum, and then it would run absolutely fine.

 

I don't know where to check next.

My hunch is a vacuum leak, but I'll take your word for it if you say vaccum is ok.

How about compression? What kind of PSI's do you have at each cylynder?

 

good luck, John

No compression gauge. (I was afraid someone would say that.)

 

 

But I'll try to double check the vacuum hoses.

[85glsw]

Yup. It was a vacuum leak.

 

I guess I'll invest in some hoses. Last time the guy gave me a fuel line, and I didn't say anything. But this time, I want a lot more hose.

 

 

Should I sacrifice a bottle of rice wine over the motor or something, so that I don't have to redo this whole thing to feel comfortable driving more than 10 minutes away from the house?

 

Oh, never mind. Thanks again.
