I didnt have carb cleaner on hand, I did blow through everything I could with my mouth to check the passages. I did verify that it does have the correct spark plug. I used some 400 grit and sanded in between the electrode and the uh, other part just slightly to clean it up. I DONT know how fresh the gas is in it, or how old that plug is, its not new for sure- light borwn coloring.
The filter, airbox and carb were very dirty, but in the part from the carb to the engine- it was like new looking inside(manifold it might be, sorry been 16+ years since I worked on bikes and I dont have a manual yet.)
The bike runs fine at wot, makes good power otherwise, but if its sitting there idling and you whack the throttle open to full it will stutter and cough before/while picking up rpms.
edit:
Im hoping its possibly bad gas or bad gas and an old plug, the kid I bought it from said he hadnt ridden it in a long time, other things werent maintained so I assume the plug wasnt.
When I picked up the bike they had put new throttle assembly and grips on it that day they said, I wondered why the throttle was slow to return so I took it apart and found they put glue on the grips and the bar lmao, so had to fix that the first day :rotfl:
