So fire it up, jumper wire on, take throttle connection off, adjust idle screw and then adjust throttle cable and reattach? Anything im missing and have I done it right so far?
ok I'll re time it to 10-12. I guess I should readjust my idle mixture screws back to factory settings first or does that matter?
ok so I need a vacuum gauge for this procedure. I read on here 8 btdc was the right number but I guess 10 can't hurt. Is that a number from a factory manual or a number that's worked well for people? Thanks for your help
I should also mention while I was adjusting the timing by moving the distributor (grabbing it by the top over the wires) I was shocked. I was wearing a leather glove but definitely felt it a couple of times. Does this mean my wires are toast as well?
8 degrees keeps the motor dummy proof from someone using 85 octane fuel with water in it (detonation) and keeps reversion at bay when when the motor is installed in a sterndrive application with a lot of tail load (extended swim platform). the distributor advance of 24 degrees makes the motor happiest to pull load with a static base timing of 12 degrees. 12 + 24 = 36.
yes, or at least the boots need dielectric grease
ok thanks that makes a lot of sense. This boat does have a large built in platform but is an inboard. I have some diaelectic grease so I'll try that first
alright, she's purring at 12 degrees idling at 800 rpm cold. Put on the dielectric grease. She starts up immediately with hardly any throttle will almost start cold with no throttle. I'm going to try to dip her in the ocean this weekend to do the idle adjustment as that's what is closest to me. I don't have a vacuum gauge right now but I will get one and check the mixture again when I get it.
I've never hooked a vacuum gauge to my boat, car for sure) I do it mostly by ear. On my 5.0 w a 1409 I find it likes it about 1.75 turns out
Yeah I did it by ear as well. Will see this weekend how she performs
