    I started a thread a week or so ago about modding my cheapo weed eater, the mtd. Well I went to pull the muff and looks like I with will have to take the whole plastic cover off or cut some of the fins to reach through them with a screw driver or socket to unbolt it, the muffler that is. That's not the big deal, the problem is that I have to have a special carb tool that has about 1/3 of the circle removed. Cause I don't have this I put it off till I can find one.

    Now to the echo. This is my bigger stronger trimmer. The Carb diaphragm or something g busted end of last season so I had to rebuild it this summer before it would even crank or run. Did it and now runs. It has always been cold natured. Like have to feathers the throttle till its warm or else it will stall. Once warm it will idle and grab it to wot and back to idle, and will stat ideling. I wanted to try and adjust the Carb to see if I could fix this cold natured issue. But there no adjustments on it, other than an idle stop. Is this normal?

    My SRM-410U is easy to start. I don't even bother with the compression release.

    Slot it with a dremel and tune with a flat headed screwdriver. I ease my string trimmer in after a cold start too, never thought to much of it. My saws will all run easy cold, but maybe getting that string trimmer head a turnin' is more work than spinning the sprocket like on a saw? Doesn't hurt to play with the tune if you know what you are doing.

    Go ahead, muff mod that and eat some weeds!

    You can't slot the half circle thing you are talking about to make it a "screw" ??

    Stupid = nonadjustable carburetors.

    It's more offspring of government regulations that make a few people feel good yet accomplish absolutely nothing.

    Is this your carb? http://www.ereplacementparts.com/carburetor-wyk186-p-521403.html

    I've seen these "big" ones on Troybilt 4 cyles and Toro 2 cycles. And they don't have H - L mix screws. Repairing a Toro Trimmer 51930 - I never could get it to run right after carb cleaning. I bought an aftermarket carb for $14 shipped from China on fleabay. It was a replacement for Honda GX35 4 stroke but ran the Toro 2 cycle like a new machine. Search "Honda GX35".

    I thought about any other Carb, but there so many different kinds of carbs that all look a like but just shuttle differences?

    Some differences are throttle plate position, throttle cable hole position, choke lever position, etc. I don't know if gas mist volume differs between them. The intake size needs to be close in size. The 2 mount holes are always the same. . I won't pay the $60 - $70 OEM price. I'll find a cheap aftermarket one that is close. Look over your carb real well and compare to $14 ones. I've bought a few from Huztl on ebay - one for $2.50/free shipping in auction format. Takes 10-15 days from China.

    Look at my link above...is that your carb? I'd stay with same " big" body size - the intakes are different from "little" carbs. Note O ring versus flat gasket.

    I know this doesn't address your issue, but I have to tell you after fighting with 4 of those trimmers and whacking off the cord to an electrical model, I bought a lithium battery powered one. It came with two batteries. I seldom use up the power of one of them when I trim. This could be a bit more powerful. I saw ones with twice the power but I didn't want to cough up the extra bucks. This one does the job just fine. It is super light and for some odd reason, I don't have to mess with feeding the line. It does it on its own. Nice to just grab it and not mess with gas or cords.

    Not sure that will hold up on the. Farm when I weed whack around the 2 acre yard. All the tree ditches bldgs etc. And I usually only do it 2x a year. Gas does not have the power most times!! I don't live on my farm so I can't keep up with it. But around my 1 acre homestead where I live battery would work as there rarely is anything out of control.

    I'll. Check when I get better signal. But unless its adjustable I don't want it. I have rebuilt this one. Reason is it totally quit. Hole in diaphragm or something. Once built it ran but runs exactly the same as it did before and well before it died.

    OK. Pay attention to throttle cable hookup. The bigger carbs tend to have a bracket w/ clamp holding outside of cable snug and a "fat coin" linkage into throttle plate. Smaller ones have a "Z" link into throttle plate and black outer tube is not secured. Give us an update on which you buy and how it works.
