2006 90hp elpto won't idle/miss/lurch....

[ecoast]

need some help troubleshooting bad idle/lurching....I do not have svc manual.


2006 90hp 2 stroke s/n: 1B358114 ELPTO

Carbs have been cleaned + link &sync


Got the boat in the water after above was done; unfortunately the jam nut on lower adjust had come loose, but line currently pointing at roller (pics)


In water, in gear, carb screws do absolutely nothing
Cannot adjust to 1000 rpm in gear as idle thumbscrew is all the way out.
Boat will get up and plane fine as long as I don't allow stall immediately after engaging in gear.


Regardless, seems to have 'miss'/rough running up to approx. 1800 rpm and dis-colored wires; and now I am looking down electrical path?


Replaced regulator (cheap)

Would like to test stator, trigger, cdm at this point, I'm thinking.

Please take a look at pics/vid and let me know what y'all think

many thanks; I'm stumped and service is booking 4 weeks out.


tldr:
need boat to idle while in gear in order to view side scan

cant see vids but i can tell you the idle timming is way to advanced on that mtr if that pic is at idle setting

[ecoast]

yessir; that's the way he gave it to me; but, as mentioned, the jam nut on the bottom of the arm had become 'undone'


thumbscrew idle adjust is all the 'out' (idle time advance) as it will only run in that position...that seems to be issue

if I move it back in at all it does not run at idle in or out of gear/water




vids should work now..?
