hey, this is an 80's lt125. i blew the carb out replaced the gas and put a spare flywheel on it. the magneto's are pretty bad looking, tomorrow i may try to swap the spare ones i have onto it. it does have light spark. we pull started it today and it ran for a minute but cut out a lot because of the old gas or something. then it would not start again after i sandblasted the old flywheel, only popped once or twice even with starting fluid.that is why i swapped the better looking flywheel. any ideas. i am guessing the magneto's are a big part. i just got to find a way to take those old rusty screws off.

 

i don't know, mine is doing the same thing. i just had my carb redone/reset, i'm going to change out all of the hoses, if this don't work, i'm selling this one cheap!!!!
