Magneto Replaced

New magneto. Just recently installed my new magneto following the wiring diagrams. Alas finally found that it was my magneto that was burned out , as when I put the new magneto in it finally starts pulling bike forward.

Problem is that the engine starts to slow when it hits 22kmp/hr, then has little burst of moving forward and slowing down. Is it possible I need to change my spark plug? I notice that when i let go of throttle bike is still moving forward fast...should i fix my throttle cable or replace it?

Any ideas would be great, bike was going 40-45kmp/hr before magneto went...replaced magneto / kill switch and CDI with brand new ones.

Thanks

Bikerguy Joe, great ideas thank, being new at this how do i check to ensure that A)My throttleslide is moving all the way up and down and B)where should the idle screw be, i heard tighten fully with fingers than do 5.5 turns counter-clockwise to loosen..is this right.


Thanks

Also to note, that I had tried taking the bike up a 45 degree incline and about 10 meters up the bike was slowing and slowing and the motor sounded like it was turn off.

Bikerguy Joe, well I think you nailed it on the head...as when I took off my gas filter on the carb and watched the needle as i twisted the throttle. It wasènt moving at all up or down. So this must be the problem, whats the best way to go about adjusting this.

Thanks
