You've probably upset the ignition timing by bumping the distributor, or some of your valve clearances are wrong.

Been fiddling with the dizzy all day. Can't set it properly cause I don't have a timing light and I can't get it to idle properly without the choke. It's currently set at the only point I could get it to start on. It seems like the 3rd cylinder isn't firing even though it's got spark, I can take out 3rd lead and it doesn't affect the lumpiness of the idle
But what about the valve clearances? I take it it's a 4K-C motor, and it has screw adjusters for the clearances.
(yes 4kc) Still gotta get around to it. Never done valve clearance before so not really sure how it works. Haven't got a manual for the 4k yet but it should the same procedures as in the 6cyl Lr manual shouldn't it (both push rod) Obviously measurements will be different.
Hey it's easy as. And absolutely necessary!!!Quote:

Cool! Time to borrow a feeler gauge methinks
Are those clearances after the engine warms up?Quote:

Hmm, the mess of lines coming from the carby is concerning. Repco and supercheap didn't have a manual for the ke70. I know it's a long shot but does anyone know which lines are important? Obviously the vacuum advance line is but all the rest seem to have nowhere important to go..
