Re: Yamaha 130 2 stroke
DO NOT remove those 1/2 brass plugs on the top aft of the carbs.
you may need the red orings for the main jets depending on carb model.
Hi I saw this old post. Why not remove the brass plug ?
Do I need to replace the red o-ring, when it looked good ?
I have done it on my carbs when I cleaned them, but the engine runs like crap.
I have tested
-compression ( equal on all cylinders
-cleaned the carbs
-new fuel pump
-new plugs
I have probleme starting the engine, I have to spray "start gas" into the carbs, and use choke, and lifte the trottle a bit.
Then I can get it run, but it stalls, and run rough.
Runs better on high rpm.
I do not think it fires on the lowest cylinder at idle.
Could it be the lower seal under the power head leaking ?
Thanks a lot, Vegard
