Universal Carb? Manual Cable Choke? Express SR & Others

[RZRob]

Hi folks,

I've had lots of various 2 stroke Honda 50s and those ByStarters seem to always have issues. My latest acquisition is an Express SR that's really clean, but it has carb issues. On this model, the bystarter is thermally reactive and attaches to the cylinder and seems to be giving the bike too much gas or not enough air. Bottomline, it's stifled and I'd like to replace the carb with a new one with manual choke. Has anyone found a universal carb that I might be able to make work? I'd like to be able to keep the factory air cleaner so the choke would need to be cable operated probably.

Can you take a pic of the intake and carb, so we can see what it looks like. You might be lucky and be able to bolt on a new intake and pop what ever carb you like. If the the bystarter is like the aeros you can make it manual with more hose and a valve.

Thanks. I'll pull it apart and take pictures. I'm hopping someone's crossed this bridge before.

If you search this forum, you will find several posts about that thermal bystarter. Rather than changing the carb, you can convert the bystarter to a manual choke using a simple fuel on/off valve. Here's a link to a thread that includes info on how to do that with an Urban Express - I think it has the same set-up.

Breaze, thank you very much for that post. I was thinking along those lines and now that it's been validated, I want to try it on mine. I'll let you know how it goes? It may be a couple weeks til I get back to it.
