spark problems

[Diesel Spree]

ok i got a 1994 elite 50cc. i rebuilt the top end in it and finally got the carb clean

so i today i tried to get it running right. and here is what it does:

it will start fine and will ideal fine

then you try to give it gas then it just boggs, but then if you do it a couple more times it will rev up and will not want to idel back down, unless you hold the rear brake to slow it down and then it will evently idel back down?????????????????????????????????????????????

ok so any ideas on that?

but then i put the fly wheel cover, or the fan cover back on and now i got no spark??????

so that is my problem. im guessing that i might have bumped a wire and it came loose???????????????


anyone have a diagram with the places i can check to see if they are getting any juice?

any ideas of what might be the problem with the spark? or the carb?



thank you so much!

Check to see if all your grounds are grounded well. Make sure the wires that are connected to the coil are crimped well. Try changing out the ignition/spark plug coil.

ok do you have or no of any diagrams that show where all the stuff is located at?

[fightingplankton]

there is a pdf in the tech doc's section of the forums. it has the entire wiring harness layout and everything.

ok i got the spark problem fixed

but now i need help on getting the thing to run right.

this is what it does:

it will start fine and will ideal fine

then you try to give it gas then it just boggs, but then if you do it a couple more times it will rev up

but then it will not want to idel back down, unless you hold the rear brake to slow it down and then it will evently idel back down??????????????

any ideas? im pretty sure the carb is clean after i cleaned it about a million times

adjust the screws on the carb. top one is throttle, bottom one is idle/air. Screw them both in all the way, and back out 1 1/4 turn, and adjust from there.

[fightingplankton]

agree with toboggan... adjust your air screw.
after that, if the problem persists, check your air filter for leaks. make sure its tight around the carb too.

ok i turned the mixture screw out just a little and it fixed it pretty much all the way except.

like lets say you are running it wideopen and you let off on the throttle and let it come almost down to idel and then hammer on the throttle then it will bogg. this is the only time it will bogg.

it wont bog if you let off then get right back on it, or if you let it idel then get on it. only when its proble like 1/4 throttle then you hammer it?????????????

[fightingplankton]

possibly flooding it too quickly. im not sure.

I have an '01 SA50 and it was doing exactly what your's was/is.

My elite didn't have a stock breather. I had to rig up a filter. It ran good with this temporary filter. When I got the stock airbox, it was missing the gasket that fits between both halves and also the filter. I wanted to see how it would run with the stock airbox. I could ride it full throttle and push 25mph. Then it would bog down and be impossible to get moving again. It all comes down to that airbox and the proper components, especially when running stock (in my case).

Check your airbox. If you're not running the stock airbox and you've done no carb / engine mods, then buy a stock air box. There are a few people parting out their SA50's here, including a 2000.

I believe the setting for the SA50 (94-01) is 1 7/8 turns from the closed position on the air screw. Mind you, this is stock.

I'd chop your plug (as found in the tech area) and go from there.

have you let it warmed up? Mine does it if i start it, and right away try to take off. If it's not warmed up, let it.

BTW, ha, if anyone has an SA50 airbox lid, in good condition, i need one! Mine has a giant * hole in it. thanks!

ok got a new air filter and now perfect

except now my spark plug cap keeps falling off

u think i need a new cap or just a new plug? or both?

[fightingplankton]

make sure the plug cap is seated into the plastic cover that goes over the engine. there is a little lip of rubber around the cap that should hold it in place.
