Cimatti City Bike - Easier Start

I recently bought a 1976 Cimatti City Bike. The previous owner got the bike running in a couple of kicks, but I've had a lot of trouble getting it started once I brought it home. There might just be a trick to it that I haven't figured out yet, but is there anything I can do or install to make it easier to get started?

Re: Cimatti City Bike - Easier Start

Are you using the choke? The choke turns itself off when you twist the throttle. You might know this but maybe not

Probably needs a new starter plate

Re: Cimatti City Bike - Easier Start

Yes. The guy I bought it from showed me how he would adjust the choke - either opening it up or closing it more - but it's not an exact science. Is there a better way to use the choke or something like that?

Omg get a sha instead of that crack bike carb. I was not referring to the choke, but the clutch starter plate.

Re: Cimatti City Bike - Easier Start

This might not be any help but it looks like your carb has been knocked around crooked..might just be my eyes and it might be fine but looks it twisted and the float bowl is almost side ways ..

Re: Cimatti City Bike - Easier Start

That is a shitty bike engine carb. You'll have alot more luck if you put the proper dellorto Sha on there. Should be a 14/12??? I think?

Re: Cimatti City Bike - Easier Start

I'll look into that, thanks! What exactly does a sha do?

Re: Cimatti City Bike - Easier Start

It is the model of carburetor, a dellorto 14.12 SHA is the original carb that came in the city bike.

The starter plate is used for engaging the engine for starting your moped. If you feel like when you’re trying to pedal start it that it isn’t “catching” it is because the ball bearing on the plate has failed and is now welded to the spring steel actuator arm thing or has worn flat.

I have found over the years that many minarelli engines do not have a crank case vent, most have a hole drilled on the side of the filler cap where you grab it to twist it off. But I have encountered more than a few that do not have them or they’re clogged.

Just get Runtang clone dellorto 15.15 off of amazon for 15 dollars. I've run three of them and had no problems

Re: Cimatti City Bike - Easier Start

Good to know, thanks for the tip. Is it a pretty easy install? Do you know of any videos or instructions online that show how to properly install it?

If you look at the carburetor on your bike you'll see it's held on by a single screw. You just have to loosen that screw, remove the fuel line and throttle cable, then put the new carb on and replace the fuel line/throttle cable

It's super easy
