272xp not getting fuel

[Brandon Bondeson]

i have a 272xp that wont get fuel, i went through cleaned the carb put in a AM carb kit it has a good fuel line and filter i've tried everything i cant get fuel to the intake port it goes into the carb but not back out. I'M JUST F**KING IRRITATED WITH THIS WHOLE PROJECT!! any ideas? is it possible that i got a faulty carb kit?

Metering lever set too low? Also double check gaskets on either side of intake block, very easy for these to fall off when reinstalling carb.

gaskets are fine. Metering lever i didn't know this was adjustable! how is it adjusted just doesn't seem possible to me lol

Bend the lever end (opposite side of needle forks) up a tiny bit. Lever will travel more - lifting needle higher = more fuel. Or get a new AM carb on ebay for $8-$10. I just bought one from DD.

ok thanks i'll try bending the lever tonight, a new carb would nice but a am very picky about certain parts something like that i'll only use OEM

I'm running an aftermarket carb from Definate Dave on one of my 272's. I've only run 5 or so tanks through the saw but have had zero isssue with the carb. I believe it cost me a whole $11 shipped through his eBay store.

maybe i'll try one but for now i'm going to try bending the lever

Yep, lever should be basically flush with carb body when viewed from the side.

I have also seen the intake manifolds crack on these saws. If you have a crack in the impulse passage it won't pull fuel.

i did check that it is fine, i have had that problem before on the same model saw

would it be a good idea to use a strait edge to lay across the carb body and adjust until it touches the strait edge but without putting pressure?

 

[cus_deluxe]

Nahhh, by eye is close enough. They do make the funny little metering lever tools for this job, and some carbs call for slightly different settings but flush with the top is a pretty good rule of thumb, i think theres a little margin for error.

 

[cus_deluxe]

If u open it up and its not significantly below the carb body you should look elsewhere for your issue.

Thanks cus_deluxe the lever was exactly the problem! It was about 1/8 to 3/16 inch below flush bent that sucker up and boom fuel in the cylinder thanks i never ever knew you could mess with those
