Hi, this is my first post, I'm very new to moped engines. I've had a 1980 Tomos Bullet SP for about 3 years now but it has rarely ran. It leaked fuel for long time and then stopped running for years. I finally have the extra money to fix it and I just got done installing new float, float gasket, petcock, fuel filter, fuel line, and spark plug.
After installation the bike took a while to start. I finally got it to run but it still has the same symptom it had from when it had ran previously. The bike runs very good on the stand with no load. I took it for a ride and when ever you give it gas it loses power. If I give it about 10% throttle I can get going and eventually make it up to full speed. I remember the bike being a lot faster and very responisve in the past.
Any ideas? Thanks
