it was stalling out after 3min
so rebuilt carb
how to slow the idle?
unfortunately, the O ring is in place so that is not the problem with the high revs. I guess I dont really understand how a 2 stoke carb works. is there a low speed jet and a high speed jet? can you adjust the low speed. the screw on the side with the spring over it does what?So the motor doesn' stall when at high revs, right ? That carb has a rubber o'ring located right in between the manifold's neck and the carb's rear body, if missing too much air will be introduced and surely the motor will rev high, check if having it, if not, will need to order part no : 309-031162 - (0'ring 2.4)

actually full story is that last season it would easily start and run well at idle and low speed but when given higher rpm would stop and not re start. so i bought a new rebuilt carb which is what is on it now with the high idle.unfortunately, the O ring is in place so that is not the problem with the high revs. I guess I dont really understand how a 2 stoke carb works. is there a low speed jet and a high speed jet? can you adjust the low speed. the screw on the side with the spring over it does what?

thanks. what would you recommend a source to obtain main jets.?Carb Tech Specs :
If being a 2.5A / 3.5A / 3.5B motor the Main Jet calls for # 92.
If being a 2.5A2 / 3.5A2 / 3.5B2 motor the Main Jet calls for # 86.
All 6 models comes factory delivered with the Jet Needle Clip Goove set second from bottom...

Sorry out of town, the Needle Valve, the one with rubber point calls for # 309031471 for any other Nissan's carb parts check Tohatsu spare carb parts : https://www.boats.net/catalog/tohatsu/2003/m3-5b2-2-stroke-tohatsu/carburetori cant find the reference to a #92 needle valve.
the nissan number i found in the schematic is 3F0031533
