Hey guys! I just bought a bicycle. It's the legendary Bros400 !! Yes !
Anyway I've not worked on bikes before. It has a problem where it only runs with choke on, and even then, as soon as any gas is given it cuts out.
I suspected main jet but took off the fuel tank, actually there's 4 small vacuum lines on the carburettor and another big vacuum line that are open to atmosphere!
1 = small passive vent, maybe just put a filter on it
2 = active vent pushing air out as engine runs
3 and 6 = strong vacuum
4 and 5 = weak vacuum
Where are these meant to plug in? Thanks..
