Fixing A Shindaiwa Trimmer That Only Runs At Full Speed

[@christopherchang115]

Yesssss a classic Japanese built Shindaiwa! Nothing comes close to how reliable and well built these are!

[@INSIDEHOUSEGARAGE]

you got that right!

[@richbl_channel]

My c. 1999 Shindaiwa C350 has been running great for years. The best investment I've made in lawn tools... ever. Yes, a bit pricey (this is a commerical grade brush cutter), but worth every penny to this day.

[@INSIDEHOUSEGARAGE]

wow nice machine!

[@kings17court]

I enjoy watching you succesfully troubleshoot, diagnose, and resolve issues. I'm not always so successful. I'm currently dealing with a early 2000s Poulan 2075 chainsaw. Last week it was running like an absolute champ. Then suddenly it started wanting to turn off. It got worse and worse, until eventually it would not start. I removed the top cover, revealing where the air filter should be. All I could see was some green dust, which I'm certain is the remaining residue of the air filter which disintegrated, and got sucked into the engine. I removed the carb, cleaned it to the best of my ability. Then I removed the muffler and the exhaust port looked fine. I put it together, and actually got it to start, but would only run at very aggresive throttle levels. Other than that it wants to bog and turn off. Frustrated, I put it away, and a couple of days later got motivated to try again. I removed the carb, and tried cleaning again, and removed the spark plug, sprayed with carb cleaner, hit with toothbrush, and sprayed with carb cleaner again. My starter rope was sagging, and hanging out a few inches, so I removed the center screw for the white plastic pulley, and took up the slack. When I reinstalled it, I forgot to put the screw that secures it. It started after a few pulls, but right then I noticed that the started rope didn't retract. The engine shut off. I realized that the rope starter coil spring came out of place, and I was not having any success at sorting that out. I jumped on ebay and found the whole starter housing at a reasonable price. It came in yesterday, and I'm about to see if I'm still dealing with the issue where it only wants to run at aggressive throttle levels. If that problem persists, what do you think the issue is, and therefore what do you think the solution is?

[@kings17court]

I've been so defeated in the past trying to be a mechanic, that I was expecting the problem to persist. But to my joy and satisfaction, it ran well. There is still a bit of a bog after it comes down and it idles for a little, but it's TOTALLY functional, and should help me finish the job. I was gonna delete my previous message, but who knows, it might help somebody at some point along the way. Also, if you provide feedback, it might add additional lessons that might add to it.

[@INSIDEHOUSEGARAGE]

thanks, first off have you done a compression test after the filter disintegrated? Also did you confirm that the filter line is connected to the correct port on the carb?

[@INSIDEHOUSEGARAGE]

thank you for not deleting it for the same reason you mentioned

[@kings17court]

@@INSIDEHOUSEGARAGE I do not have a compression tester, so no I have not done that. If by filter line you mean the line that brings fuel from the tank to the carb, I feel very confident that it's connected correctly.

[@INSIDEHOUSEGARAGE]

good then, just check the compression with a borrowed tester and you'll have a better idea of what the problem might be.

[@johnleady3810]

Good trimmer, Shindaiwa are bulletproof in my opinion

[@INSIDEHOUSEGARAGE]

they are certainly on a level of their own!

[@samuelandrade9246]

Yes I would use this trimmer. A very well built unit.😊

[@INSIDEHOUSEGARAGE]

thank you!

[@SHOINOFF]

That was a nice looing and running trimmer. They deffinetly dont make them last like they used to.

[@INSIDEHOUSEGARAGE]

You got that right! I miss this level of quality.

[@24BLUEELMO]

Id love that machine . Just the fact that the carb is a mini motorcycle style carb

[@INSIDEHOUSEGARAGE]

yes you've obviously seen a couple of motorcycle carbs then!

[@kings17court]

I was thinking the same thing. Seeing that slide come out was wild. I've become accustomed to the odd little carbs with the diaphragms and plastic sheet valves, etc. But I've got to admit, those new style carbs work darn good as long as you don't let them sit too long without use.

[@lewiemcneely9143]

My 1st trimmer was a Stihl that size. A WHOPPER and ended up running the table saw blade on it. Also, when mixing a batch of gas/oil I ran some gas from the pump into the oil bottle and rinsing ALL the oil out of the bottle into the gas mix to get EVERY BIT into the mix. Always Stihl orange bottle. The synthetic slobbered too much. Was with you with the slide. Good fix and happy week!

[@INSIDEHOUSEGARAGE]

is the Stihl oil that good? If so, I might have to try It out

[@jesterr7133]

Well, my good week continues. I got another one of my long term riding mower projects up and running for the first time in about five years. About five years ago, I realized that I had enough Troy Bilt/MTD riding mower parts in my stash to build an entire machine, so I did. I spent about a month and built this machine completely from the ground up. I was quite proud of it, but the engine started acting up on the first test drive. I was so disgusted that I pushed it into my lean to and didn't touch it again for five years. I pulled it out yesterday and had it running in about 45 minutes. It was just a Nikki needle and seat failure, and the engine was full of gas. I feel really stupid for letting it sit. I still have to swap out a tire and replace a few miscellaneous parts that were missing, but I should be able to test drive tomorrow. I've knocked two push mowers and 1 riding mower out of the project queue in the last ten days, and I should knock this mower out tomorrow. I might actually get to my trimmers after all, lol. I just have one more John Deere riding mower left after this one. I'm going to have a ton of stuff to sell in Spring. I have two riding mowers and four push mowers ready right now.

[@INSIDEHOUSEGARAGE]

wow you've been super productive!

[@jesterr7133]

@@INSIDEHOUSEGARAGE The part that is even better is that the battery that was in it is still good. The batteries in both riding mowers I got running this week were still good. One sat for three years, and the other for five. This one is seven years old, and charged to 12.85.

[@kirbyyasha]

Yesssss. It seems just lovely would love one of those. Also seems it has another 20 years of life or more easily.

[@INSIDEHOUSEGARAGE]

Nice, glad to see someone understand the true beauty of this machine!

[@jesterr7133]

I have never heard of this particular brand before. It is a very interesting machine. Thanks for showing it.

[@INSIDEHOUSEGARAGE]

Thanks for watching, and they've been around for awhile, but they might not be available in your area.

[@MrRmh3481]

I would use it. I like the long reach and appreciate the older Japanese engines. Im sure you noticed all the small ties and guard pieces. This one was made to be fixable. Carb Adjust; H 2 1/4, L 1/2. Looks like the carb parts are available. Good Job!

[@Nukemann64]

Lol, that baffles me that the primer line just shoots the fuel out on the ground! My dad's old Homelite ST-185 had that same setup with the primer. When you'd prime it, it'd squirt the fuel out. I always thought that was so weird, now i understand why. Pre Emissions BS! I'd LOVE to find a Shindaiwa T27 or T270 trimmer, I always thought they were such a beautiful unit, and damn are they ever! You can really tell that sucker was built to last till the end of time. It's hard to beat that classic Japanese engineering.

[@INSIDEHOUSEGARAGE]

you got that right, these are wonderful machines built to last.

[@covishen]

I would love to have that trimmer. i have several areas that I don't want to use my mowers that need clearing.

[@INSIDEHOUSEGARAGE]

[@shawndubay4050]

Oh heck yeah I would love to have one of those.

[@INSIDEHOUSEGARAGE]

[@shawndubay4050]

@INSIDEHOUSEGARAGE if I could find one that is affordable and in good condition I would buy it in a heartbeat. I do have a Stihl FS-250R with four or five different blades and a string head. I call it my leveler because it clears all that is green and growing up to four inches. It's a heavy beast but it's unstoppable.

[@INSIDEHOUSEGARAGE]

wow you're very fortunate to have the 250R, I wasn't able to get a hold of one before they discontinued them.

[@ethanmiller3935]

That piston has carbon buildup on the skirt. It should be aluminum colored, not that brown/black color. That junk can cause carbon scoring and harm the cylinder. Good Modern FD rated oils can be run at 40:1 (50:1 for some oils is a little skimpy) in old equipment and not be an issue. The older oils didn't work as well and therefore needed more of it to provide adequate lubrication. I use amsoil saber and it works great and keeps engines clean.

[@INSIDEHOUSEGARAGE]

I do believe you are correct

[@INSIDEHOUSEGARAGE]

that would work for me.

[@berardia4]

Why does the fuel return line not go into the tank? Just not made that way back then?

[@briantii]

Old school just throw away fuel you aren't using. In general aviation you have to sump the fuel tanks for water. In the old days it was normal to just dump the fuel sample on the ground. Leaded fuel. Some aircraft even just had a "pull to drain sump" knob where it'd pee Leaded fuel out the side. These days the normal is to sample the fuel in to a special jar that allows filtering water and debris out and pouring back into the fuel tanks. But old school was dump it. Just like popular mechanics magazine in the 1950s instructed people to dump their engine oil into a hole in the ground. Thankfully we've all moved on from that too.

[@berardia4]

@@briantii sounds like a fire hazard at the least.
