A3 engine question

Nick Eiselstein /

i was wondering if a 1986 golden bullet A3 engine will fit on my 1981 Silver Bullet moped. I have the encarwi carb, but I am not sure if this 1986 engine had the delloreto or encarwi carb.

Re: A3 engine question

Of course it will! Any Tomos moped motor will mount up to any Tomos moped frame! Even the newest A-55. But, the 86 should have had the Dellorto carb.

it will fit if its an a3 and not the a3n.

only if its the a3n.

on the right hand side of the cylinder, one of the fins will have a letter n with a circle around it.
