Question: TB2020XP Carb Adjustment

282859

The link has been removed on the TB80 carb adjustment. My TB will only run with the choke partially on. That indicates that it is running lean. I need to adjust the high speed needle, but I guess the EPA got into the business of requiring special tools for these adjustments.

you would need to adjust the low speed needle

Question: Model TB80EC TroyBilt Trimmer

How do you access the carb adjustment screws on the TB80ec

Reply: Model TB80EC TroyBilt Trimmer

Without the specific tool for those screws, you can improvise. Diaphragm carbs nowadays have 4 different types of mixture screws used in them 1. Splined (pretty common) 2. D-Head 3. Double-D Head 4. Pac Man
In a pinch you can use a 22 gauge automotive wire connector. I like the female spade terminal connector. These connectors are plastic, so they expand somewhat and grip the screws. Tap one of them onto the screw head until tight, and then adjust. I use the female spade part as the handle. Careful adjusting, as these carbs are sensitive. Here is a LINK to the proper way to adjust a carburetor on the Troy Bilt.

Question: Lower Shaft Replacement

elzie

the spring loaded button that positions the lower shaft with the upper shaft broke. having to order part because I can't use a screw to keep shaft from rotating in use because the drive shaft runs through. the top is easy but was concered that the lower part would be tricky to put into the housing that curves downward. are there any springs or items I should be aware of before taking off the old lower shaft? the unit is only a year old and has been used maybe less than 20 times.

Hello 1203598,

The replacement of the 753-08164 Lower Boom Assembly, should not be difficult. You will just need to remove the 753-06571 Gear Box Assembly and the 753-06123 Shield Assembly. There are no springs or hidden parts that you should be concerned with. Just make sure you line up the drive shaft into the coupling and Gear Box, and you should be good to go.

Hello General,

Instead of explaining on what happens when oil is not mixed with gas for a 2 cycle engine. We have a short article and video on How to Mix 2-Cycle Engine Oil. Watch the video to see what happens.

Hope this helps,

Question: Gearbox Assembly

cote1966

Can I order a straight gear box instead of the angled gear box? The one I ordered did not last but one season
WJA
Reply: Gearbox Assembly

WJA

Hello cote1966,

I don't think another gearbox assembly would work on a different model trimmer other than the one it has in the parts diagram. It may not connect correctly with the model you have.

-WJA
can you get just the upper drive shaft without the housing assembly
WJA
Reply: Upper Drive Shaft And Housing As...

WJA

Hello dolphin1,

On this model the only way you can get the upper drive shaft is by ordering the part number 753-04344 upper drive shaft and housing assembly.

Question: Connections Inside Fuel Tank

AQ557Z

I have two connections (hoses) inside the fuel tank, one has the fuel filter and the other seems to serve no purpose at all, and yet it has a small tube connector on the end (inside the fuel tank) am I missing something?
UtahAV
Reply: Connections Inside Fuel Tank

UtahAV

The line with the filter is the feed line to the carburetor. The other line is the priming return line. No idea why the fitting would be inside the tank. Those little fittings are commonly used on the exterior of the tank. Most manufactures don't use the fittings anymore. They used to attach the two fuel lines to the tank with a short lead on each tube. Then a longer piece of line was attached to one or both lines as needed to reach the carb. Most tank assemblies now just have longer pieces of line installed so the joining piece is not needed.

Hope this helps,

Question: Gear Box Assembly

1151943

this may be a really dumb comment- I am assuming that the gears and ball bearing are inside the part as shown and are included in the assembly price. Is this correct?
WJA
Reply: Gear Box Assembly

WJA

Hello 1151943,

Your assumption is correct. All the gears and bearings are included in the 753-06571 gear box assembly.

-WJA
Is this part the same as 753-06571 that is used on a Craftsman weed trimmer? The part looks the same but that doesn't mean much.

Hello jriggen,

You can consider yourself safe in ordering part number 753-06571 for your Craftsman trimmer. It's probably made for Sears by the company that manufactured that one.
