I've sealed all the seals I could, tightened all bolts, replaced carb, and I've done everything. The only thing I haven't done is replacing the electrical components I know I wired correctly and I know the magneto isn't upside down but, maybe one of the 2 components are bad. My engine starts but I have to keep pedaling to keep it started so, should I get a new magneto or new CDI. Please help.
