Hello everyone, So I need to change the name of this topic as my project started!  For some reasons the electronic ignition came back to life... Now, it's running really poorly that was kind of expected. When I open the choke fully it dies, I guess it's too lean so I'll have to change the idling and main jets. I didn't make the baffle yet and I still didn't receive my new pods so I'll have to wait for this being done. I found it kind of unresponsive/delayed when twisting the throttle. Also, it's kind of ticking on the top engine so I'll have to check those valves. When I checked the spark, it wasn't huge either... You can watch/ hear it below : https://www.youtube.com/watch?v=af05AX-ZU94&ab_channel=TheTallTomhttps://www.youtube.com/watch?v=tm86UACgQyk&ab_channel=TheTallTomLet me know what you guys think Thanks Tom

Alright after a day of fight. I can say it, no more overflow! I had to raise some float to 23mm. I don’t know if some spring got more resistance or anything else but it works... I’ve put everything back on try the spark and.... no spark, I’ve seen a live wire grounding from the electronic ignition... it might be blown inside now. Reading on the coils after the plug caps is 5000ohms, weird. I have to investigate this now

I sticked the floats up high to see if I had any leaks and nothing. So it’s definitely float/valve related

I’ll make 1 post per photo so you can have some good quality

Yes indeed. I don’t know why or what happened in the past to have this fitted

Thinking the spring in the float valve maybe too stiff and prevent the valve to close properly

@macabethiele, the slider open fully but I have a gap that I do not have at the bottom. Im pretty sure their is more play on 1 arm set as I can feel it but I do not think it is a big deal. If it is, I will change them.
So the float looks upside down for me too but they were that way when I opened them (it does nott mean it is right but they are going the same way on cmsnl)
I managed to have them not leaking with a higher float so the valves are sealing properly
I tried to change the shape of the Float tab were the valve is Seating on to make sure the pin does not get jammed. But it does not work...

I figured out the pin for the floats are getting stuck...
I’ve attached some photos to make sure I do the things right

@macabethiele I found the culprit, it’s the arm set link that got more play on carb on 1 & 2 not sure if I’ll change it for the price! https://www.cmsnl.com/honda-cb550f-super-sport-550-four-1976-usa_model467/arm-set-alink_16018323004/#.X1oSxyV4WEc@julie, I’ve set up the float height following your topic but its overflowing quite a lot on 2 of those. I’m really desperate with those carbs. They are from a cb550 f1 so the height should be 22mm and I made sure both sides of the float were level. Maybe my overflowing pipe too low for some reasons as I’ve seen they were slightly bent, all the bits inside are new so that can’t be this The carb reference is 069A Keihin

Actually I start to have a massive doubt about my multimeter reading. I’m pretty bad at it
I attached a photo of the reading of the coils HT
What are your thoughts?
@macabethiele I’ll have a look tomorrow at this

Hey,
So I tested the plug caps + coil resistance
Plug caps are at 4.5/ 5K ohms so that should be ok
Coil resistance is at 25K ohms for both so all good on that side!
I’m waiting for the new spark plugs to arrive now. Should be on Thursday.
Now I figured another odd thing with the carbs. I tried to sync the sliders with drill bits. But when I open the sliders fully, I always have a gap with carb #2 and #1, the 2 others looks fine. Could you have sliders lifting up at different speed? I should probably create a topic about this.
Thanks
Tom

@julie thanks!
Out of curiosity, how do you know they have a resistor? The spark plugs were DR7ES so the wrong ones!
I'm wondering if that bike was really running in the past now...
