Hi guys I'm new to the forum and just getting my head around it so I apologise if this is already covered.
I bought a 76 CB750 k a few months ago. I was so excited that I changed the oil out, clean up all of the electrical connections. New pugs, bulbs and cables and fired her up. She ran first kick sounded slightly clunky. I tensioned the cam chain and that was that. She ran perfect every time I fired her up. As far as I was aware she had not been run for 2 years prior to my purchase.
So.. I decided to clean the carbs. I pulled them cleaned and checked all jets, floats needles etc. everything seemed fine except a bit of crud in one of the main jets and a pilot jet ( not in the same carb ).
I fixed everything back to gather being as careful as possible.
Now she struggles to start with and without choke. Slightly better with. When she does fire the revs drop and cut out when I apply throttle. I have checked all of the boots for leaks. I can only find one screw in the side of the carbs (not the plug screw).i can't get her running long enough to do any tuning.
Thanks
Dan
