My quad will not start when temperature is below 40 F. Starts and runs great in warmer temperatures. My choke doesn't seem to be working...should the plunger be "IN" (down) or "out" (up) to actually "Choke"? Not the little choke lever...the actual plunger in the carb?

Are you sure it is actually in neutral? Try rocking it back and forth while clicking down on the shifter.

Thanks Mech! I knew we would get at the RIGHT answer...even at the expense of my ignorance! 🙂

Yep, solenoid is not engaging...the starter actually has two functions built into it. A solenoid moves the starter gear forward to engage with the engine as the starter motor is spinning. That same solenoid retracts the starter gear when you release the switch so that the engine does not continue to spin the starter. Take it back off and figure out what you did to make the solenoid not work...

It will still run...lights will not work unless it is in that position.

My 250 is 5 clicks DOWN is neutral...green light should come on. Each click "up" is the next gear. When riding, release the throttle and shift to the next gear. Gear up for higher speed/less torque...gear down for more torque (climbing)/less speed.

Rotating clockwise...OFF, ON, LIGHTS

Works for me EVERY time!🙃

Now that it's all better, I can tell you... My initial thought at "won't turn over" was GO FASTER AND TURN THE HANDLEBARS SHARPLY

Are you sure it is in neutral? With the key "on", click down on the shifter until the green neutral light comes on.

Where would I find this crankcase vent? I have a similar problem

I was NOT able to get it to smoke by manipulating the throttle as described. This is the result after a short ride. Also, when I remove the filler cap with it idling, there is enough pressure to lift the cap at the last thread...no hissing or pressure buildup. With the cap OFF, engine speed slows slightly and exhaust comes out the filler cap just like the exhaust pipe. The breather filter is saturated with oil and there is oil standing in the housing. Sound like it needs rings?

My 1998 Suzuki Quadrunner starts well and idles steady with no smoke...until ridden. Here are SEVEN short videos showing the problem. Please watch in sequence and help me diagnose the problem and develop next steps to repair it. Videos may be in following posts. Thanks, in advance, for your words of wisdom.

Two thoughts...and I'm not familiar with your quad AT ALL. Check your fuel shutoff (petcock). If it has the auto shutoff valve with a vacuum connection, start there. The vacuum line or the diaphragm in the valve could have a leak. Oil in the air filter housing could also indicate a vacuum issue. Again, just guessing...I am confident the experts on here will get it sorted out...

This quad was a hot mess two weeks ago when I got it. I've been tinkering on it and have it running pretty good. It didn't have a pull start. I just got one and installed it today. Here's a little video of my first try at using it. Hope it's worthy of a "onya" from Mech! 🙂 IMG_3274_Trim.mp4

Mech..I'm betting the positions on the petcock, based on the symbols, are up is "normal" (taller standpipe), down is "reserve" (shorter standpipe), and horizontal is "off". That "hose opening upwards" is not connected to the carb. It disappears into the instrument panel and I can blow through it. I think it's what was connected to the original petcock valve.

Mech...I knew you would try to help! Thank you! Here are some pics...I do not have the vacuum petcock. Looks like someone might have replaced it already. There is a short piece of hose on the carb that is plugged. I assume (you know the acronym I bet...) that is where the petcock was connected. There is also a piece of hose, disconnected, that disappears under the dashboard. Probably the original petcock vacuum hose. What are the positions on the petcock shown?

I just bought this a couple of weeks ago. The oil sightglass was FULL. When I opened the fill plug, oil/gasoline LITERALLY gushed out and flowed for several seconds...FROM THE FILL PLUG! I drained it, changed the filter (no metal bits), and refilled with new oil. Opened up the carb and cleaned the float needle. Blew into the fuel inlet while manipulating the float and it seems to work. Buttoned everything back up and it runs good. Now my question...was the fuel getting into the engine because of a stuck float needle or is there something else wrong?

Operator error! With the rearend raised. it shifted through all gears while rotating the wheels! Thanks Mech! Now I just need to learn how to ride it! 🙂

As soon as I get the front wheels back on so I can try the rocking thing, I'll get back to you. Right now, stationary with engine off, 1st and 2nd make a distinct "click" when shifting. Further "pulls"/toe-taps on the shifter feel like shorter travel against a "mushy" stop...if that makes sense. No matter how many time I try shifting "up", two clicks down takes me back to neutral. When I have more info about "rocking" or even riding results, I'll post again. Thanks again for your help!

I have tinkered on a Chinese GY6 150cc. It stalls unless the idle is set high.
