#26 carter carb woes!!

[cmatthew]

pulled the carb, soaked it and did a rebuild. floats in good floaty shape. put her back together and fuel was coming from the air cleaner. so i adjusted the tab on the float to make it ride lower. its at a pretty good angle down now. it stopped the leak. rode it around and fine tuned her. parked her and came back a few hours later and still no leaks. thought i had it. this morning though it was bad news. leaking out the air cleaner again. how much of an angle can i put on this float? as much as it takes before it starts to starve for fuel maybe?

Many people will tell you the float needs to be "level" or whatever the gauge requires.

The fuel level in the bowl effects engine performance.

I would bet there is a different problem.

Dirt, old rubber from a deteriorated line, defective needle or seat, the list goes on and on.

Sorry, I do not think I could be lucky enough to hit the one answer.

has the seat and needle been cleaned/replaced during the rebuild.

the float valve and seat is new. i noticed that the new float valve has a rubber tip on it where it contacts the float tab. new seals, new high rev needle, and throttle bushing. how tight should the float valve seat be in the carb body. i have it pretty snug right now.

It shouldn't need to be that tight.. .I think there's an oring around it isn't there?

You sure that float is good?

Mine was leaking gas and I discovered that my fuel bowl breather drilling was clogged. Might be something easy to look at.

there is an o-ring and it is made of metal same as the one that came out. all holes were blown out with air. i will check the float again and make sure there is nothing stuck in the float valve.

Unless this is a carb needle like I've never seen before and has a rubber tip on each end, you've got the needle in backwards, and I'd have to wonder how it's sealing at all.

On the carbs I've rebuilt, the needle valves did have a rubber tip. The end that contacted the actual float was still flat metal. Anybody else seen the needle valves with the rubber ends against a float? Maybe the wrong needle valve??? The rubber tip would go into the seat, not against the float. No offense, but it's not in backwards is it? Just throwing out ideas........
Snug the float valve seat. Don't over tighten. I've seen em stripped out by PO's with a little RTV applied . Good luck and keep us posted.

Dang Matt,
You type faster than me, LOL............
