just bought my kid a xtreme x49 50cc qaud....im getting fuel and have good compression....i can get a little spark if i fire it up with a screwdriver in the coil wire but with a plug i get very little if any spark and thoughts????????????

 

Do you have the correct plug cap.....(otherwords right top on the plug)
Some may have a terminal stud ...or terminal nut.......
With just the threads.............or with the nut installed........Something to check first!!

Did you have it running yet?
Maybe the top spark plug nut threaded off and is now stuck in the plug cap?
Does the spark plug "SNAP" into the cap?.........
.......caper.......

 

2 stroke, fouled plug, just replace with new plug and use a 40:1 or 50:1 mixture

 

i took a look at that today the plug is threaded on top ...the terminal isnt....it does snap in though i dont think anything broke off in there....i havent had it started i bought it broke..these little chinese things arent set up like anything else i have though....if the plugs threaded should it have something to screw into>???thank you for repling

 

yea its not a two stroke luv thanx for the advice though

 

O.K. You said the top of the spark plug is threaded.........
Now make sure that little terminal nut did not come loose and get stuck into the plug cap....
Do worry if you can't find the nut for the top of the plug............Some don't use it........It may just snap into the plug cap with the terminal stud showing like you have.....Did you try and keep the plug attached to the wire when removed from the motor and ground the plug to the engine and try and pull of crank over...............Do you get spark that way ............Caper..........

 

yea i tried that i cant get spark that way but if i put a screwdriver in the wire and ground it i can get a very small amount of spark...i bought a new plug today and still nothing...i also noticed a hose coming off the cylinder that pumps air out when i crank it but its not attached to anything another one doing the same thats hooked on the vacum side of the carb

 

Check that the coil has a good ground. Most of the coils are bolted to the frame and depend upon the 'physical' connection for the coil ground. Sometimes paint interferes with the 'electrical' connection. Try scraping some paint off the frame where the coil mounts.
