I have a 1961 R27 I just bought receintly.

It starts very hard when cold, usually I have to push it but after it warms up a little, as little as around one block, it starts good.

But when I am riding it and stop it increases in speed when it is idling. It runs down the road great.

I have had the Bing Carb apart two times. Everything looks good the slide spring seems good and the slide works good. I checked the throttle at the grip and it seems to be working good also. The last time I had it apart it put gas in the float bowl to see of the float would float and it seemed to do that also. I don't know these real good but I am learning. Thanks for any help.

It seems possible to me that you have an air leak between the carb and the head. it is not uncommon for folks to overtighten the 2 nuts holding the carb on and bend the "ears" of the carb. This leak causes very hard starting. To fix it you can either _
1 take the carb off and use a glassplate and grinding compound to make the mating surface flat again.
2 take the carb off and put some soft gasket cement on the gasket/heat blocker on the studs - then put the carb back on.
Hopefully this helps.
