pull start ease

[raaazzzeee]

I finally got my pullstart on,BUT like always somthing happened. When i pull the pull start it doesn't seam to catch until about 10in then it turns the engine over once. How can i fix this? Also once i get it started it will die if i touch the brake at all. I also have to richen the LSN about 1-2 turns to start it then, once its going, (to get it to work properly(sp?) i have to lean it back about 1-2 turns. I'm pulling my hair out over this one. ANY help would be greatly appreciated.

you need to open you r idle at a point where it is about 1 to 2 mm wide , yours is too closed , in my opinion, for your pullstart, your owb might be stripped

Try cleaning out the one way bearing. Chances are, either the starting shaft is worn down too much, or the one way bearing is worn out, OR it is just dirty...

Ok, How should i clean it? Wash it then re-oil?

Soak it in DA (denatured alchohol), run a paper towel through it and spin the bearing on the towel that's through it to work out any dirt/grime. Clean the shaft it rides on, then oil the bearing lightly with some 3-in-1 (light oil). If it still doesn't grab, replace both the shaft and bearing. Replacing just the bearing won't work for very long since the shaft would be worn. It would actually shorten the life of a new bearing.

I typically have to adjust my throttle trim on the radio to open the carb an extra mm or so for starting. Then I back the trim down. I don't ever mess with the carb needles or the carb idle screw to start.

Alright all problems SEEM to be resolved , except now my carb screw (the one that holds it on) fell of, and the carb slid around and falls off often. Besides a new needle what can i do to fix this?

Needle? Get a new carb neck screw. Don't run it without one. Your damaging your engine if you do. Air leaks are the number 1 killer of RC engines. (well, pretty close to #1)
