So I'll preface this by saying that I have perused the shop manual for the necessary specs, and I've been given a good heap of information that way; however I believe I'm now in need of the knowledge of how to apply such information.
The story goes like this, I purchased a 1973 Cl175 for $500, in decent shape, bored out .50 over with new pistons, rings and some other upper end work. It ran alright albeit on one cylinder the majority of the time. It had a bit of work done to it at a shop and when it came out it flitted in between one and two cylinders without the air filters attached. It idled around 3-4000 without air filters and at points went up to 6000. Every once in a while it would manage to hang on at around 1500 and I was able to take it out. She hit 60 mph in 4th so I can assume she was doing pretty alright for a 40 year old. I took some time off from starting her up so I could fix and replace other sketchy items (rear wheel, speedo/tach, headlight, rusty gas tank). I completed that laundry list a couple days ago and started her up again. She did pretty decent, idling around 1500, yet she still putted along on one cylinder. Compression and spark were and still are mint, so I figured the only thing holding her back from running on two again would be the carbs. Naturally I pulled them off, soaked them in a seafoam and gas mixture overnight and pieced everything back together.
I pulled the air screw out about .8/.9 turns and the idle screw about 3.5 turns out. I put the carbs on and attempted to start her again, however she would only start for a second every once in a while with the choke on and then sputter out when I tried to give gas. Compression and spark are still great. My only guess would be that one or more of my carb variables are off, possibly because of the bored cylinders. Here's a more practical list of symptoms:
• Engine turns but fails to start unless choked and then only for a second
• Pretty dry spark plug tips
• Very little fuel in the float bowl
I appreciate the viewing and apologize for spinning such a long tale. I'd love to answer anymore specifying questions if you all have them.
ps. I have no mechanical experience other than this venture
