Carb Rebuild, O Ring sizes, no idle
Posted: Mon Jun 27, 2016 1:00 pm
So now that I got the engine running mint I really want to fix the idle problems.
It runs super shitty as you can see in this video:

It never ran great btw.. :D
If you let it sit for a couple of seconds it will drop down to 2k until it slowly dies. Sometimes the idle is at 2k, sometimes 2,5k, 4k, 1k. Blipping the throttle really changes it.
The carb is getting no false air from any leaks on the intake sockets.
With the throttle wide open the bike behaves as it should: quick throttle response, linear power build up, fast declining rpm when the throttle is released
The float valves almost look brand new.
The mixture screws have been set to 1 1/4 turns out.
I roughly tried to synchronize them, but it is impossible! The bike just constantly dies.
When I turn in the idle screw it rises up to 6k, half turn out --> dies.
The float height is on all carbs between 14 and 15mm.
Carbs have been cleaned with an air compressor.
Now my guess is that the o rings on the carb tops might be bad.
Does anyone have the exact sizes of inner and outer diameter (thickness)?
Do you have any more suggestions what might be wrong with the carbs?
