Ke70 Problems :(

[Heath.]

hey guys :/

 

 

 

never ending problems really. but here is number 4213.

 

finally the ke gets on the road. new battery and fuel filter so it should have ran sweet but!

 

i have just put a 32/36 webber on my 4k. but when i drive it. it runs but as soon as i hit a hill it dies. it just runs out of fuel.

 

 

 

its like it can't make it too the webber, any ideas :( this is really killing me now guys :bash:

hmm... you better join the other gentleman with fuel problems and do a flow test.

 

Take the fuel line off the carb and put it in a jar, take the coil lead off and crank the car for 15seconds. Measure how much fuel it pumps. I can do the same and we will see if your fuel pump/lines etc are delivering enough fuel.

 

Actually, you need to be dead sure it is running out of fuel... could it be too rich and it dies?

 

Are the jets correct?? You should whip the jets out, check that they are clean and post up the sizes of the airs/emulsions & fuel jets on here. Some of the guys with Webers can tell you if they are OK.

 

Most likely I'd say the secondaries are blocked, so it will run on the primary throttle but when you boot it up a hill & open the secondaries no fuel goes in, just air. Strip out al the jets (idles too) note the sizes and push petrol through them and the drillings with a syringe or blow compressed air through it all.

 

Float level is another point- I don't know if it is adjustable in the downdraughts like the DCOEs are, but if it is too low it will lean out. Something to check when you have the top off the carb.

should i do this testt on flat ground?? (into the bottle one)

I don't think it matters, so long as the pump can pick up fuel from the tank is should run at the same output pressure.

 

Whip the Weber off and strip it to clean it, and do the pump test while the pipe is floating there.
