I’ll figure it out. What do you recommend testing first?

As mentioned in my original post the previous seller included a few extra parts in the sale, including a new and unopened 4 pin CDI. I installed the part but got the same results. One thing I noticed is this black wire with a yellow stripe not connected to anything else on the quad. Another wire with the same color scheme is attached on one end to the key and nothing else on the other. Is this the cause of my problems? I have attached photos of the CDI and ignition switch below.

My bad. I meant to type gas. Anyways the quad doesn’t spark which leads me to believe that there is a wiring issue somewhere as the starter motor can be spun even when the quad is in the “stop” position. Any help would be greatly appreciated.

I have attempted to start the quad today to no avail. It cranks and the plug (which was new) had oil on it but it refuses to start. I think it might be an electrical issue as it still cranks even when the lull switch is at the “stop” position. Any ideas what might be going on?

I figured out that the ignition coil is at fault. I will not be able to work on it until July 23 due to being out of town. Thank you for all your help!

Good news! The starter works and cranks the engine. However the engine no longer sparks. What could be the issue here?

The starter is fine, nothing broken there. How would I go about checking the starter clutch?

No it does. not

I know for a fact that the starter itself works as I tested it before installing it. What should be my next course of action?

I don’t know what happens when I use the electric starter but when I crank the engine with a wrench the gear on the crankshaft connected to the gear on the starter slips and does not engage the crank. Are you sure that using the electric starter when the cover is off and without oil will not damage the engine.

I found a digital owner’s manual and discovered that the quad is in fact a 150 and not a 125 like I thought initially. Not sure what good this does but just putting it out there. http://www.bajamotorsports.com/system/documents/126_OWNERS_MANUAL_-_BA150_14_yr_Owners_Manual_VIN_prefix_LLC_.pdf

I did take off a gear and the flywheel from the shaft in the pictures above. The left side is very different from the right side in appearance and size. Thank you for all of your help today but it is getting quite late where I am and it is difficult to see with my dim garage lights. I will continue working tomorrow. Here is a picture of the left side of the quad. I believe it hosts the CVT as the end of the cover leads to the chain that turns the wheels.

I hope these new photos are good enough. All of them come from the right side of the quad with the transmission on the left.

Just before I go tearing things apart with no idea how to put them back is the clutch the large grey disk visible in the first photo?

I am totally confused now. If the quad does not have a clutch then why do the wheels not connect to the engine? And how could I bump start it? Back to the starter not engaging I believe the thing that I took a picture of in the second to last image is shearing off (if not completely gone already). Could that be the cause of my issues? Thanks a lot for your help.

Just something I forgot to add: The clutch still has resistance and springs back after I release it, hence the reason I did not suspect a problem with it.

As I said before I am new to this kind of stuff and completely failed to notice the clutch cylinder. Would this result in the clutch not disengaging? Thank you for your reply.

The quad has a clutch and a CVT. The clutch does not appear to do anything as the engine does not seem to be connected to the wheels regardless of whether the clutch is pulled in or not. The clutch is only for starting and stopping, not for running through any gears.

As I stated previously the quad is equipped with a CVT and does not have gears to run through. Also the starter is not connected and when I crank the engine the large gear on the crankshaft that is connected to the starter gears slips past the shaft. Is that normal?

Yes. When I push the quad with or without the clutch there is no engine resistance. This type of quad has a CVT so there might be something I am missing. There is no pull start (only electric). Thanks for the reply. Oh and I am cranking it with a wrench.

The title pretty much explains it all. When using the starter I can hear it spinning but not engaging the engine. The wheels also do not engage with the wheels when the clutch is out. The motor has compression if that helps. I am new to engine work and repair and I bought this quad with the idea of fixing it up (not knowing the full extent of the damage). The previous owner said it ran but sat for a year (I don’t believe that for a second after opening it up) and had bought a few new plugs and a starter motor, none of which fixed the issue. Any help would be greatly appreciated! I have attached a few pics of what I think could be wrong.
