I need some help with my carbs as the bike is hard to start & runs badly. I've done the engines head gasket as it had blown, valves, shims etc rebuilt the carbs with new O rings I got from variable valves suck but it still runs very rough.
I had some O rings that didn't fit the carbs left over & a couple that were not quite the same as the old ones but assumed they had shrunk or something, is this normal with these O ring kits?
The bike runs cold with bad flat spots so I think it could be the old running rich problem although it helps with the choke on .
Does the choke richen or lean out the mixture?
Any help would be great.
