Just finished putting a Grubee GT5 on a friend's mountain bike. The engine runs like dog unless you switch on the choke, just a little bit. I'm thinking i might have a vacuum leak to locate. With the choke part way on, the engine accellerates much better, even when up to operating temperature. Turn the choke off and it instantly bogs down. It's a fresh engine so it might need a little more break in. I've got two good heat cycles in it right now. Will try another one tomorrow.
Andy help is appreciated.
