Best of luck. hopefully after battery full charged. and fresh fuel will help.

@stinkwheel
you are spot on, my engine was actually not turning over. i will check amp meter next time i go near the bike.

Hi all,

Just a quick update on the non starter issue.

I charged the battery, checked the pushrods for any problems. At TDC, they were both spinning ok, but the intake pushrod has a really tiny up and down movement. I decided not to touch the pushrods until i made sure that the battery isn’t the problem. I installed the battery but the bike still didn’t start. I checked the spark plug to see if there is a spark and noticed the the plug was dry., which means petrol wasn’t getting to the piston. I took the carburetor apart and cleaned it again, and opned the mixture screw 2 turns. Right now the bike does start if i open the throttle a tiny bit, and i can rev up the bike but it doesn’t stay idle no matter what i try: closing or opening the idle screw doesn’t do any thing and the engine doesn’t idle at all. Unless the intake pushrod has such an effect on the bikes idle, i believe that the problem is with in the carb, or the ignition points. I later opened the points cover and saw that the bottom point has a white mark on ot. I’m not sure why or if it has an effect on idling but ill try to adjust the points once i get some spare time.

With this new information, do you guys have any ideas on why the bike doesn’t idle?

Thanks in advance!

Daniel

There is also a "throttle stop screw" which is intended to lift the slide slightly off the stop and allow a small amount of air through. If this is screwed too far out there will be no clearance and therefore no air getting through meaning you must hold the throttle slightly open to keep it running. The best way to adjust it is to take off the air filter, watch the slide and adjust the screw inwards until you see the slide lift. Do not touch the throttle at this stage. A tiny lift is all you're looking for. It is also important that the engine is good and hot when testing these adjustments, heat makes the mixture weaker and a cold engine runs rich. Good luck,

Mark M, do you mean the idle adjustment screw?
If so, i have tried sevral positions but still couldn’t get the bike ti idle.

No. They are separate. That's why I called it the throttle stop screw and not the idle adjustment although they both contribute to the speed at which the bike will (or won't!) idle. The idle adjustment meters fuel and the throttle stop meters air, you need both of course. This is a simplified explanation and I'm not familiar with the terminology used on the Micarb so sorry if that's not quite the term used in any Micarb literature. If I knew of one I would refer you to a diagram of the Micarb, can anyone do this and highlight the components? The Parts Book diagram isn't specific enough. On the positive side, you are very near to fixing this problem so don't give up!

Thanks Alan R!

The two screws im familiar with are 15 idle screw and 17 mixture screw. And i tried to adjust both but with no luck.
