as i ride off road or even on the road , my engine occasionally cuts off. I have no idea why? Could it be oil levels? everything appears to look fine. Also i throw out my shoulder trying to start the engine, most of the time if i give it gas it turns on, and it'll stay on for a short period of time then cut off, could this be idle speed? I'm not to sure what these problems could be from. overall the Loc206 is awesome

Pork, I just wrote you a beautifully written response only to cut and paste our carburetor tuning guide which erased my entire response. I'm devastated!! With that said this response will not be poetry.

Your engine stalling right after you start it tells me that your idle setting is likely too low. The engine should idle around 1,700 rpm. To see how your carburetor works and initial settings that we recommend I would check out our Carb tuning guide in the NEWS section

http://www.briggsandstratton.com/engines-racing/news/Carburetor%20Tuning%20Guide/

Your engine shutting off and how it's shutting off makes me think that your ground wire is either loose or the wire insulation has maybe rubbed to the wire somewhere. The lack of insulation or a lose connection (at the switch or the connection to the ignition module itself)could be causing the ignition to ground itself (shutoff) when you hit a bump. The way to diagnose this would be to disconnect the ground wire where it goes into the back of the ignition module. If that causes the situation to go away then you just need to see if the connection needs to be crimped tighter or use some electrical tape where it might have rubbed through.

Just remember that disconnecting the ground means you will need to reconnect the wire or disconnect the spark plug to shut off the engine. The easiest is to put it on a stand, recreate the condition and check whether it is your switch or ground wire.

Thank you I set my idle to 1700 it was at like 1200.
Now I don't mean to ask such a stupid question but what's the ground wire and where would it be located. :/

Pork, It's a fair question. I am more concerned about my horrible photo but I challenge you to hold your phone, an ignition module, and try pointing at two different points on a Friday afternoon. lol

You have your switch on the front of the control cover. There is a wire that runs from this, under your control cover, to the back of the module. When you push and hold your button down it breaks the connection in the circuit stopping the ignition from firing.

Now, my thumb points out WHERE your ground wire attaches to the engine. My other finger is trying to point out where you can access with a pair of needle nose pliers the connection to disconnect.

Obviously the engine should be off, pull the wire off and towards the intake manifold/carburetor so you can connect it after you see if the ground wire or switch is your issue.

Again, you can pull the spark plug wire at the spark plug to shut the engine off. If you can recreate this condition while it is safely up on the kart stand I would suggest doing it that way.

Let us know if that is your issue and we can go from there!

thank you for your patience and help, I'm not sure if you attached a picture to your last post sounded like you did but i never saw one, but with the information you gave me I took a look at the wires and I believe i saw what you were talking about except i never pulled any wire out bc I wasn't to sure which one to pull out, but i took a look at the connections and took a look at if any wire seemed to be stripped or about to break etc. Everything looked fine, I also took the carb off and cleaned it and checked the float i believe everything looked fine, I drove my kart for a while yesterday i believe it cut off at most twice, which is the least amount it has done. The good note is when i took it on the road and opened the throttle and got to drive it for 15-20 min first time since i ran it that it never turned off mid ride, so i'll take it as a step forward, I'll ride it again around my property today and keep you updated. crossing my fingers that it wont cut off on me.

Now i have realized since day one of running it, that i can get it started with one pull. After running for a while, i'll turn it off and lets say i come back to it 5-10 min later, is it normal that it takes a few more pulls this time while giving it gas to get it started. Throwing out my shoulder is no fun haha. if i turn it off should i give it more time to start it up? or should that not matter.

overall i do love this engine, unfortunately i'm running it on a custom yard kart, but its the most fun I've had in 23 years of my life haha. I plan on saving up for a racing kart there's two tracks in Jersey I can race at and I want to get into. Sorry went on a off topic i'll keep you updated tomorrow on if the engine turns off again.
