I just took the car out on a 50 km drive.

It still chugs in the low rpm's and has a "put put put" out of the tailpipe at idle.

The economy gauge at idle in gear is about halfway.

The car also smells of fuel slightly like it is running rich? Fuel gauge moved a bit and I only travelled 50 km.

I have not touched the mixture.

After I floor the accelerator and the rev's climb above 4 grand the car flies like it is brand new.

The car starts perfectly though and on the first crank everytime.

Have I screwed something up when putting the fuel lines on again?

I don't have any smoke coming out of the tailpipe or anything.

I've done some hard, foot-to-floorboard stomps on the highway and no smoke or anything else. Car does very well on the highway with the rev's up. Economy gauge is always at minimum unless you floor the accelerator.

I must have done something wrong here. The car just idles and drives lumpy in the low revs.

Can someone point me in a direction to look at things? I don't have any backfires or anything like that.

I need a plan of attack.

Thank you for reading and please offer anything that comes to mind.

Many thanks,

Michael McKinney
