Crazy Guy on a Bicycle
I've had my HF 6.5 clone engine for a long time now, and I had some issues with it running rough. I use it a LOT, as every day transportation for my bicycle, so it gets run pretty hard.
I took the carburetor apart, and cleaned all the jets, and removed dirt from the breathing holes in the gaskets, and it's running just fine now, and getting excellent power again....
However, it's still rough to start when it's cold. I have to choke it nearly every time when I shut it off, even if warm. I have to give it throttle when I pull the rope to start it, and hold the throttle for a few seconds until it runs good before I can open the choke and it then will idle normally. Sometimes it shoots a blue flame out the exhaust...
I tried an old car sparkplug, and it started a little better, but not much difference. I'm wondering if it's not the carburetor causing rough starts.... I'm thinking of trying a BOSCH platinum 2 or 4 sparkplugs if a new champion plug doesn't help.
Any ideas? I know the engine isn't new anymore, but it still runs like new when warm.
