ear shave question

So I did the ear shave a couple weeks ago but havent really troubleshooted my issue yet. My issue is that i can start the bike cold and it starts right up but it I shut off the bike and restart it, it acts like the bike is flooded out. I have plugged both of the 1/8" lines on the carbs and have a breaker on the crankcase ventilator.... I have 142/142 jets... 2 1/2 turns out on the airscrew.... Im only using one shim

Did I miss something?

This here is not right. But i think it is a mistake on your part. The first jet should be like a two diget number. Like 40 pilot and 140 main.

plugged both 1/8" lines?

I don't think that is right.

I only plugged the line on my right side carb. Is there one on the left. I will look at my bike in the morning

There is one per carb, I have tried it both ways with just the right one plugged and with both plugged.... Did you put a filter on the left one or did you leave it open?

The one on the left side goes to the petcock IIRC

IIRC= If I Remember Correctly
Vacumn line from left carb goes to the middle nipple on the petcock (fuel valve) on the bottom left side of the fuel tank.

Hope I understood your question correctly bjd.
Otherwise this answer is going sound really dumb.

Thanks Hoss... I knew what the petcock was just wasnt sure what a "petcock iirc" was... I thought it was something new... Good ol acronyms!!!

Since I changed out the tank, I had to install a new petcock and it only has one exit wound. Is there possibly another place I could run that vacuum line? Ill have to look at the stock tank and look at the petcock on there, maybe I can fab something up...

No expert here, but the stock petcock is vacuum regulated, and the carbs are gravity fed fuel as long as there is vacuum on the petcock.

Perhaps if your new petcock is gravity fed, but not regulated ion any way, therefore always open, perhaps the fact that the bike acts like it is flooded is because it actually is flooded.

Just a thought. Perhaps someone else with more experience/knowledge will chime in soon.

?????Hmmm?????

Nice observation and thats something to look at but that poses a question for me... When the bowl fills, and the float raises then closing the hole inlet for fuel to enter the carb, the fuel shoulnt be entering the carb regardless whether the petcock is vacuum activated or not, right? Am I not correct on this? OR... am I just not understanding the way the CV Carb works?
