CNew 404 #1 Posted April 3, 2019 I’m rebuilding a carburetor and it has the little metal mesh screen. I’ve read on earlier posts that these are prone to clogging. I recall a David posting a service bulletin as well that recommended removing the screen. Before I button this back up - is it the consensus here to just remove the little screen and not worry about it? Share this post Link to post Share on other sites
Webhead 95 #2 Posted April 3, 2019 Leave it. I've never had a problem with them. Use clean fuel and a good pre-filter. Share this post Link to post Share on other sites
CNew 404 #3 Posted April 3, 2019 Great thanks! I took it out to clean everything up so I’ll see if I can reattach it and then close it all back up. Share this post Link to post Share on other sites
Wallfish 698 #4 Posted April 3, 2019 I leave them in there as well but these aren't being run very often either. Share this post Link to post Share on other sites

"I have a service bulletin in my dealer's manual that notifies all techs to remove the screen from the carb, on any engines that they worked on. Apparently the screen getting clogged caused more problems than if there was no screen at all. The later carbs were completely void of the screen."

There was an O&R service bulletin recommending that the carb fuel filter should be removed as it caused too many problems, later carbs don't have the second fuel filter. I just cleaned the filter on mine, as the tank filter is missing and the in-line filter I bought still lets some dirt through. I can't see where I posted the actual service bulletin, but I could find the above two mentions of the carb screen filter. I've left them in place too in any carbs I found them in, I think the above picture shows why they are actually a good idea, they clog to let you know the tank needs a more through cleaning.

CNew 404 #6 Posted April 4, 2019 Great, thanks David! I think I’ll attempt to reinstall the screen on this carb. Clint Share this post Link to post Share on other sites
