Default RE: problem with my os 46 ax

BTW, right after getting an engine started you want to let it warm up and you want to clear out any excess fuel from the starting process.

We often do things starting that put raw fuel in the crankcase. And lots of people start their engines at half or less throttle. No matter, if the engine starts, let it run at low to medium speed while you move stuff out of the way.

I usually start with 3 clicks on the throttle from throttle stick closed. And when they start I let 'em run that speed while removing the igniter and such. And I listen all the while. And about the time I get 'em out of the hold down, they pickup speed a bit. I've always believed that pickup is the excess clearing at about the same time they've warmed up enough. I give them a steady throttle up and listen. And I look at the exhaust for some visible. After you've done it a couple of times you know what you want to hear and what you want to see. Depending on the weather the needle may take a click one way or the other.

The engine is then cleared out and warm, and needle probably set ok. I bring it to idle and let it run some at idle. Now it can be checked to see if it'll take a quick throttle up. If not.......... pinch the sucker. If you try to test before you've gotten the primary needle set at least close, and before the starting fuel is cleaned out, and before the engine has had a bit of flatout run, it'll drive you crazy.

And we don't need anymore crazy modelers.......
