I recently acquired a very nice low miles 80 CB750F.
The previous owner acquired it after it had sat for a long time. He overhauled the brake system, new cables, chain, filters , checked valve lash, new cam cover gasket etc.
He had the Carb's professionally cleaned and new gaskets, accelerator pumps and air bypass valves. Also new manifold boots.
Probably need to be sync'ed
it is very hard starting,,,,, cranks and cranks then some struggles to come to life, stalls a couple times then finally keep it running, and start to take the choke off, it pop's and runs poorly and no power.
Plugs are soot black. Checked the timing and its on.
Obviously its running super rich, So where to start? ignition, or carbs?
Any insight would be appreciated.
