<DIV>My carbs are open. You say there is no lack of air. I didn't tell you I 
live 110 deg. weather. Would there be a lack of cold air, or does it 
matter?</DIV>
<DIV>I did the jetting with help from Bergs. </DIV>

<DIV>Air jet 185</DIV>
<DIV>Spark plugs are running nice med. brown.</DIV>
<DIV>Symptoms are vapor lock after I turn it off, sometimes boiling in carb 
floats. &nbsp;Which gets me to believe I'm running a bit hotter then I would 
like. So I wanted ask if there is tips on running cooler with this set up.</DIV>
<DIV>&nbsp;</DIV>
<DIV>Sorry if I didn't post right. Don't want to ofend anyone. </DIV>

  I<BR>&gt; believe that my carbs are not getting enough air at higher rpms and 
  maybe at<BR>&gt; low too. My question is; How do I get more air into the

  you're barking up the wrong tree. Those carbs <BR>are plenty big, and with 
  those carbs I don't think you can be using the stock <BR>air cleaner and 
  ducting, so they must be completely open. There is no lack of <BR>air in the 
  engine compartment.&nbsp; <BR><BR>What are your symptoms and why do you 
  suspect that they are caused by lack of <BR>air? Is it possible that your 
  jetting is just too rich? That might seem like a <BR>"lack of air" but the 
  solution is correct jetting.<BR><BR>Keep in mind that any aftermarket carb you 
  buy will need to be rejetted after <BR>you put it on your engine. (Yes, I 
  know, the people who sold you the carbs <BR>didn't tell you this. 
  Sorry.)<BR><BR>PS: Thanks for changing the subject line to something
