Small Engine Troubleshooting Problems? Ask a Mechanic Now.
IThis spring, the TC-210 which has been an animal would barely run. I pulled the carb, it was really crummy from probably ethanol. Due to time restriction, I ordered a new one. It ran better, but still ran rough, could not get to hight speed, idled rough. Chased everything, fuel, lines, compression, spark arrestor. Turns out it I think it was the gasket between the carb and manifold. Put a little RTV on it and we are running. But we are not truly functional. It starts easily.I can't keep it running in idle. When I lift it up and rev it, it goes to a high rpm but can't sustain it. It falls off to half speed. The carb screws are currently set at H 1 1/2 turns. L at 1 1/4. The carb had the needles out much farther when I got it. Not sure really how to optimize. I have made small changes to both, only changing one at a time, but still not working. Help!
I have done all of that. I used the old gasket with RTV just to see if that was the problem. I installed a new gasket. Not sure what the torq setting should be on the carb, but I guess I can disassemble and see if it was leaking. This is extremely frustrating. Maybe there is something I didn't do.
Had some challenges with compression testing. Different testers were giving me different results as there were for big engines. Bought one, a good one, and got 150.
I can't really keep the thing running to actually open up and adjust the low speed. There has to be something else.
When I put the new carb on, it did not run any better at first.
I have removed the muffler and spark plug arrestor previously. How do I check for scores? Is there something I should take a picture of and send to you?
ok, hang tight. Let me take the spark arrestor back off for a good pic.
Nope. Only if I keep reving it. Interesting discovery. Disclaimer: Yes, I know that when setting the screws, you have to be very careful not to go into far. I was very careful, as soon as it hit stop, I stopped. Pulled the screw, and the tip is messed up. Took the idle screw from the old one, and same thing happened. Now this is high idle. So I will get another one. Bad carb? Kind of weird?
So here is what happens. Two pulls with choke on, and it starts to kick. Take off choke, starts. Even with idle screw all the way in, can't keep ir running. I have to keep revving. When I lift the tiller up and hold it down, it will go to the high idle, but an't keep it. Wonder if I can send you a video. I thought for sure you were going to ask me if I was a photographer.
ok, here is another thing...When I bought the new carb, I searched Echo TC-210 Carb that was sent is C1UK82.
When I check the parts catalog for my serial number, they have: C1UK54A. The boss says for TC-210, but I don't know if they are compatible or not.
No and Nada. Let me check.
I did check the gasket, the big white thing. was in good shape.
Ok, so that's good. Now where do we go?
It should be ok considering it's new unless the fuel filter wasn't connected to the fuel line when starting. But anything is possible.There could be an air leak.Did you notice if it were wet around the cylinder or carb adapter? Did you replace the tank grommet too? Fuel lines are hooked up correctly?
Sorry for the delay. On Generator. Bad storms wiped out the power everywhere.
Here are the pics, enjoy.
This Just Answer is trying me to ask another question for $36 bucks.
Do you see the pics I attached earlier?
Which wire? I see the gasket is wet,the new one that I ordered. Missing the wire though. Was going to use super fancy RTV made by MerCruiser. It's really great stuff.
What about the carb gasket pics?
