BF40 Carb Removal

[Navigator]

Hi All,<br />Got a question. I'm having a cylinder drop out when I back off the throttle quickly, then it stumbles a bit and usually kicks back in. It definitely fuel related. I've checked everything and I've narrowed it down to a carb problem. <br /><br />My question, (yes I have the manual) When you go to remove the carbs, do you take the entire Intake manifold off with carbs attached or do you take the carbs off individually. The manual is a bit unclear and I'm trying to save a bit of work if I can. It seems taking the mainfold off then separating the carbs is the way to go.<br /><br />Nav

Your correct, pull the whole manifold...When you pull them apart pay close attention to the small but long jet, this gets clogged easily and the hole inside that jet requires a very small jet cleaner, not torch tip cleaner, can't remember the size. Also, when you reasemble them they should be sync'ed with a vac,merc, or digital gauge all measures vac...you can do it by ear but it's not the best way, adj. pilot jets too...

Robards,<br />Thanks for the tip. Thats what I thought but I just wanted to be sure. I have the vac guage and I've done syncing before. Thats the easy part!<br /><br />Nav
