DTR will only start with easy start

[Calum]

Hello there,

I found on my dt that it would never ever start, without the choke. Put the choke on and it starts first kick. As soon as I upgraded the carb, thag problem went away.

@Calum hi mate. Thanks for replying. choke is on. I've tried with choke on, choke off throttle wide open etc. Do you know what carb I could get that would fit a DTR 2002?

@runes sure there's a place I see that sells then new I think for 130 but eBay sells the old round slide carbs for 20 they should fit but I don't know for

@runes Sounds to me that the mixer screw is the problem, as the mixture is wrong. It's either rusted or been abused and consequently the engines fuel/air mixture is wrong. If the plug is getting wet, surely that's from over fueling and the engine running too rich? Which would cause the starting problem you are experiencing.

I would get a new mixer screw fitted before doing anything else, so that you can adjust the mixture correctly and hopefully that should solve your problem. Then that way you will know for-sure if the engine's mix is correct and eliminate that from your suspected fault list before throwing a ton of cash on it. What RPM does the bike idle at???

You starter jets are both blocked by the sounds of it, the one on the carb body and the one in the float bowl. Common problem with none starting tm28,s

Very old post but should help people who think these carbs are a nightmare when they have a starting problem with them.
