Choke is still being funky

[jurgenkoppen]

Hey all gurus,

After tweaking and teasing my restore project now for over a year, the 2 remaining issues are:
Choke action on my 80SG is still defeating me, and the speedo is still squeeling and showing about 15miles less then it should over 50 mph.
Choke:
I had the carbs out at least 4 times, and she is now purring, balanced, and has lots of power.
But cold starting is still embarrassing. My other '79 bursts into life in 1/2 second flat with the choke out, but the 80SG I have to crank for 6-10 seconds, and then it sputters into existence in a most disgraceful manner.
Before I take out the carbs one more time, can somebody please tell me what passages to focus on (I do know that the thin tube coming from float bowl tiny opening at bottom goes to the diaphragm area and on into the choke space to hole in throat), or better, how to effectively get whatever is blocking out of there .

On the speedo, I used silicon spray to lubricate behinf reed switch. Mistake? Not effective for long for sure.

Any thoughts?
Thanks, Jürgen

Sounds like

Your idle mix is way too lean, just turn the idle mix screws out 1/2 turn to start and don't forget the most important part, synchronization.

Use a toothpick or similar to put a little grease on the worm gears behind the reed switch and lube the cable from the front wheel and check that the part on the front wheel is properly installed.

Hi Jurgen,

If the choke is not working, it could be the choke jet???

It is not in the main body of the carb at all, but in the base of the float bowl. Easy to miss!

You should be able to shoot carb cleaner through the jet; once you know it is in the bowl, you will find it.
