Callen 64 #1 Posted March 18, 2012 520 Dies at WOT. Can choke it and it will keep running, clean out run for a bit an do it again, I cleaned the carb yesterday and it died out 1 time then ran for 1/2 hour. Started it this afternoon to move it out of the shop and died out again. This time, I noticed the vaccuum gauge fell to "0" when it started to die. When it dies, it will start right back up. Any Idea where to go next? Loose Valve seat? TIA, Chester Share this post Link to post Share on other sites
smoreau 658 #2 Posted March 18, 2012 It's possible the sealant between the intake half's is causing a intake leak. Share this post Link to post Share on other sites
