My OS .50 Hyper won't start. It's not drawing in fuel.

Is it most likely a "clunk clog"???

What's the easiest / quickest way to diagnose and fix??

Thanks

Take the line off the carb and the muffler, then blow lightly threw the line that was on the muffler. If fuel comes out of the line that was hooked to the carb then it is not the clunk. Next move to the carb. take a piece of fuel line and try to blow threw it and see if you can get air threw the carb. if not then you have found your plug.

Have you checked the condition of all fuel and clunk lines?

Do you have a fuel filter between the main tank (or header tank) and the carb? If so, have you tried removing it and just running fuel line directly from tank to carb to see if the engine will start then?

It's fixed. I took the line off the carb and blew.

it dislodged the clog.

Thanks for the ideas!

You saved me plenty of time!!

Good thought; I tried it at the field.
