Have got a KE70 i recently purchased as a daily.
The carby that was on it was stuffed. the secondaries wouldn't open, and was bogging down heaps under load going up a hill.
Replaced the inlet manifold exhaust manifold and carby from a early KE30.
Has way more get up and go in her, but the idle sucks, it wanders anywhere from 500rpm to 1000rpm. sometimes it will sit at around 750rpm steady.
Also it started making a funny knock noise on way home just now. checked under oil cap and there was a small trace of milky crap. the coolant is still good, no bubbles or oil crap. maybe just condensation in the oil cap?
also the exhaust is sitting on the gearbox cross member, is that a problem i should be fixing asap? all ive noticed is more vibrations.
I'm ready to give up on cars and just send it to a mechanic and say FIX IT!!
