TaoTao ATA250D Starting Noise

chas1956 · 01-18-2019, 10:21 PM

I have a 250D that sounds terrible when your starting it. It's hard to describe but it almost sounds like it trys to turn backward or trying to backfire. I'm looking for a good supplier for parts that's honest & dependable. If you have any ideas of what could be making this noise please share with me.

As human being says its likely the starter clutch. My ATA250D has always done it but I ignore it because it always starts right up. My other CG engines do it now and then also.

Yeah but what is a 9 roller? Only thing I can think of is some sort of gangsta slang.

humanbeing could you explain what 9 rollers and 16/20 are please and what the difference is?

the noise isn't a squeal it's a loud almost grinding noise and it's kinda like it's trying to pop back through the carb. I felt the gear and won't let me turn it but one way but it does let me move it back & forth (side to side).

ok I have another question a friend just brought up.
my starter is a 9 gear and my starter drive clutch is a 18 gear so is that correct? He said maybe the gear combination is wrong & making the noise. Does anyone know what the correct starter gear & starter clutch gear should be. Were just trying to figure out what could be making all this noise. As I've stated this isn't a squealing sound.

Humanbeing is saying that the typical starter one-way drive clutch has 9 rollers (or sprags). He gave you a link to a better quality example that uses 20 sprags. He also guided you towards using Loctite.
