In answer to all you guys it was the flywheel.. I thought I had reposted the results but guess not... The flywheel had week magnets. Just to be clear Ive been all over the internet now the past 2 yrs and im not the only one with this issue with this motor... The factory will even tell you its...

Anyway just a update. I ordered the flywheel and should have it in the next week or so. Once I get it back together and verify it runs Ill let you guys know....

Thanks for the reply. Ive done alot of research and found although I could have the magnets recharged most magneto shops dont have the specs for this flywheel. If the poles on the magnets somehow flipped they would just be recharging the magnets in the same direction which wouldnt help much.. I...

Hey guys, I dont mean to hi jack this post but I wanted to let you guys know. I have the same go kart the manco 710E mines a 2004 and I too have a bent front A arm. When I bought the kart it was like that. I got the part number and searched every where and like you guys were saying the a arms...

Tested the boot its fine. Took my coil to a friend with my boot.. Turns out he had a motor that uses the same coil We pulled the coil from his motor and thru mine on... Coils fine... I have a bad flywheel.... Working on getting one ordered....

I guess its possible I got a defective new coil.....Because I did replace it already... The only thing I havent checked is the plastic spark plug boot that attaches to the wire... Was gonna ohm test it today but got buisey with other projects.....

Still working on this issue... I finally found some spark. Using a spark plug tester that has adjustable gap I closed the gap to .6mm and started seeing spark. Almost immediately when I started opening up the gap on the tester my spark started weekening and I got intermintent spark... My spark...

Thanks for the info. I contacted robin subaru technical support team direct, They agreed with you but also said if I had a known good coil that it had to be the flywheel cause those are the only 2 items that cause my engine to have spark other then if I had a short to ground to my coil. Im...

My coil has 2 spots you have to gap using a feeler gauge rather then the standard single location. Using the manual and there specs of 3mm I gapped both locations using 2 feeler gauges one for each location.... I called Robin subaru direct, They indicated only 2 things that cause spark on that...

I think I just figured it out.... The flywheel acts as a magnet and the coil has a magnetto built into it on this engine. I also have a charging coil inside the flywheel used to charge the battery... On this engine what runs the engines spark is the ignition coil and the flywheel... So if I...

theres only 3 things that run the ignition on my motor... The ignition coil which I guess is considered a magneto , the charging coil which I would call a stator and the flywheel which has magnets inside it... Then theres a voltage regulator/rectifier which im told can be disconnected cause all...

Ya I did all that.... The go kart has been garaged all its like so its very clean but I did clean the flywheel with 220 wet sand paper to clean any rust.. I gapped the air gap to .3 mm as it says in the manual....And I replaced the spark plug with the ngk replacement. WHats strange to me is...

My flywheel looks exactly like yours and im dealing with the same issue no spark... I beleive though that the grove there is considered normal. Theres a step there for the coil to clear and I dont thing the sensor there on the flywheel is replaceable... You have to replace the whole flywheel...

Anyway one? Im still fighting this this thing! Im wondering if theres a sensor built into the flywheel that can be bad cause the only thing else to replace is the charging coil.... I always thought they called that part a stator but in the parts manual they called it a charging coil..... I only...

I have a ex27 motor with no spark... I disconnected the 2 orange wires from the charging coil to the regulator and checked the charging coil for shorts to ground and for opens between the 2 wires... checked good. Ive left the wires from the charging coil to the voltage regulator disconnected...

I know this post is a bit old but did you ever figure out the no spark issue. I have the same cart with the same problem.... No spark....I eplaced the coil and still no spark. I ohmed tested the stator and it doesnt appear to have any shorts to ground and it has continutity between the two...

Thanks, I found the wiring diagram thru another site for the actual cart ... ANd manuals for the engine thru subaru robin site so I should be good. Thanks though for pointing that out... Didn,t notice the date...

Thanks man, I did learn the wiring of the regulator. Its just for the battery and lights... Easy way to know if it works is if your engine runs then its producing ac voltage... Other wise it wouldnt have spark.. So if its running and the regulator is wired correctly, check voltage at the battery...

Ok Ive answered my own questions.. This is the voltage regulator and is only for running lights and the battery... With it disconnected the engine should stll run... I found the wiring diagram here http://www.tricountysupply.com/illustratedpartslist.htm and a list of all the parts for my Go...

ok so ive been researching all night. It appears that box with all the wires and the two wires coming out the engine are for running lights and charging the battery and nothing more... If I disconnect the 2 orange wires as there pictured in the pics above the engine should start and run without...
