How do you guys get these dang fiddly little things to work? I haven't figured out any of them, from a buncha cox 049s (threw em out ), my buddies norvel 061 (works some of the time) Even a OS 25 la is finnicky. Whats wrong?!?!?!?!

Thanks

You really need to give some spacifics on what the problem is. I have a few cox a norvell .061 and a few o.s. la motors that have never given me trouble( except when i ran too small of fuel line on the norvell or the leaky back plates of the o.s. engines)...So you can see most problems come from the user....give some details, there is a few people here that can help...
Aaron-

Aaron is right. In my days (which isn't really that long) I have owned 8 engines. I only had problems with one which turned out to be a faulty carb. And if you can't get an LA to work then you need some tuning practice. Do a search for Ron Paris engine tuning. He is considered to be the best tuner in r/c car racing.

I have found that the small engines will be VERY picky until they are fully broken in (a lot of run time)
