Greetings gentlemen!
So I picked up my first bike, a '79 CB750K 10th Anniversary Ltd. a few weeks ago and purchased some supplies today (filter, oil, spark plugs, battery, charger/tender).
After some repeated attempts with very little success, I'm unable to get the bike to start. She cranks over, but it's as though she's not getting proper fueling.
I noticed that when I turn the fuel tank petcock from the OFF position to either the ON or RES positions, the bottom of the carb starts to leak like a tap. I really don't think it's supposed to leak that much.
I'm pretty new when it comes to carbs, but I have been working on autos with EFI for the past 3-1/2 years, so I'm definitely up for tackling this challenge. I'd just like some insight before I start to take everything apart.
I was told by the previous owner that it would benefit from a rebuild, as it's been sitting and only been ran once a month since 1998. I plan on putting velocity stacks w/ a screen mesh filter on it and an exhaust in the future, so I've been told that I'd have to get larger primary jets.
Can anyone point me in the right direction regarding the carb rebuild/jet upgrade?
First thing's first though, I'd like to get that leak dealt with. I've included a photo and encircled the areas where fuel begins to run the moment I move the petcock out of the OFF position. Why would it be leaking this much, and would this be a reason why my bike doesn't want to start?
Thanks
