4k Ignition Timing

[japlish]

hello,

a friend and I went and picked up his ke70 on the weekend, it had some problems starting so we went and got a new coil and new dist cap, it already had new spark plugs too. anyway we eventually got it started (the points were replaced but not set correctly) and it was all good,

 

on the way to a mates place it was pinging like crazy when you tried to go a little fast then normal so we checked the timing and it was on like 30* btdc!! i tried to bring it back to around 8 or 10 but it would die at around 15?

 

whats goin on?

[DearmanKE]

how high is it idleing when its on 30btdc ?

if its idleing at like over 1.5k (like mine does) then that wont be acurate and compareable to stock which is 8

just bring it back bit by bit until it doesnt ping anymore, even if its still way over 8,

but i guess thats only relevent if u have a high idle? do you?

you can turn it down on the carby

then check your timeing again, it should be a little less crazy,

 

but yeah, quick fix, retard timeing by ear a little, test, repeat, until it doesnt ping

yeah it does idle pretty high (don't have a tacho though) we just wound it back until it idled okish, we're putting a tacho in soon so i'll find out then.

yeah with my idle i run approximatly 25 btdc i think or it could be closer to 20 but yeh, coz it idles so high its way different coz of the advance mechanism

[Clapped out]

It's always a MUST to disconnect the vaccum advance (vaccum hose) to the dissy when timing an engine,

 

gives a more accurate reading,
