What your saying isn't true at all. A primer has nothing at all to do with cooling, I have no idea where you got that from... And the primer just sucks gas into the carb, it doesnt squirt gas into the combustion chamber, your thinking of a push mower. It doesn't do any thing with lubrication either. A weed eater also has a carb with diaphrams which means that it can run at all Angles, which is why you can edge with them. A carbureted engine with a float would stall if you tilted it on its side.

Thanks, saved me from having to explain it more. You are completely correct.

He must be getting his info from the kids working at Lowes or Home Depot. :laugh:

 

I found some of the people in the dealer don't even know what they are talking about.:laugh: Forget Home Depot and Lowes.

 

fuel lubricates and cools. if you don't believe me, talk to anyone who knows anything about engines. when you prime it, and there is fuel all the way to the carb, what happens to the fuel once the carb fills up if you keep priming it? I don't know about your trimmers, but mine says you should prime it X number of times, and I know for sure it has fuel in the carb before that number is reached. are you telling me there is no fuel in the engine until you pull it? that would be asinine, because then there would be nothing to start it and lubricate it.

That's correct. You're starting to learn here. When you shut the engine off, there is oil still smothering all the internal parts that doesn't get burned. When you prime it, all you're doing is getting the fuel up to the carb, nothing more. You can push the primer bulb 100 times and all it will do is circulate through the lines out of the tank up to the carb (not through it into the engine) and right back to the tank.

 

This may sound weird, but I swear there is a connection. My 265Ts will start to run a little weird upside down when the exhaust port starts to get buildup in it. I pop the muffler off and use a small screwdriver to carefully clean it out. RPMs go back up and no more problem with not working upside down. I was going nuts with the tank, vent, and fuel pickup and nothing ever helped.

 

to oregonmower, that's interesting, then, because newer ones all say to prime so many times, some around 10. you would think that would wear the diaphragm and primer bulb to "over" prime it so many times. good to know that my gut instinct was right, though, I only need to prime it until there's definitely gas in the carb.

cbegap, their trimmer is new, as is mine so while it's possible, it's not likely.

I still maintain the quickest, cheapest, easiest solution is a change in habit, as I did. I definitely wouldn't move the fuel pickup to the filler neck, I would try weighting it, then if it still doesn't work as you want it to, take it back to the echo dealer and make them fix it, since it's still under warranty.

"orangemower"

It might take on average, that many times to get the fuel up to the carb. Manuals are for people without any mechanical ability or common sense.
it doesn't go "in" the carb just "to" the carb. The residual fuel/oil left in the engine after you shut it off will still be there to fire the next time.

Orange mower is right, it doesn't matter how many times you prime the engine it doesn't matter. I think you need to do a little reasearch on weed eater engines, and im pretty sure that just about ever one know that in a 2 stroke the oil lubricates the engine, but thanks for your knowledge.

It needs more gas turn the fuel needles there are two Go over to mechanic and search there is a lot on this.

This is actually a very common problem. It's due to mixing your gas to rich, and the carbonized fuel builds up. Not enough exhaust pressure can escape causing too
Much back pressure

I found my problem was that I had the two lines from the fuel tank to the carb connected backwards, or where the other one should be in both cases. I noticed the yellow line was going dry and the engine would stop. So I found a YouTube where some gal showed the lines in the paper orientation, I pulled them off and changed them out on the carb and now the thing is running in any position within reason.

 

I have a new echo 225 trimmer that runs great but if I turn sideways to edge with half tank of fuel or less it dies after edging 5-10'. With a full tank it does fine. Anybody know an easy fix or is it a known problem with this trimmer? Posted via Mobile Device

I have put in the new carburetor, fuel filter and air filter. When I flip it over now, it shuts off. what's up with that?. Cranks with no problem
