How to set the timing on 1986 yfm225

One day i was ridding my quad and it had hit a pot hole and then it died it had no compression so i took the cover to the cam and the screw that turns the motor. It was loose. I tighten the screw and try-ed to start it it would not so i took the carb off and it was shooting gas into the air breather. So i need to know how to set the timing on it, to see if thats the problem. It has spark and gas.

Theres fuel starvation, the carbs are not getting required fuel in other words the float chambers doesnt get the correct amount of fuel .
Check the fuel flow from the petcock to the carburators.
Check the float pin and adjust accordingly to get the right level inthe float chamber of each carburator.
Hope this helps!

The air/fuel screws won't have any effect on the top end. That would be governed by the main jet. Did you install the Boyseen Reeds? If this is a new addition it could be the problem. Another thing could be the fuel level in the carburetor bowl. When you tore down the carb it is possible the float got out of adjustment. You could drop the bowl and see if the fuel level is correct. If not, bend the tab on the float to adjust it.

I hit a pot hole and my battery died the next morning. I got it tested and it was bad. I bent both right side wheels after hitting a pot hole. My car won't stay charged. Active steering is off too.

I would check all earth wire on your car , as it sounds if there is a bad earth wire or a broken one ., this would explain your battery going flat and the flat battery would probably cause your problem with the steering as it will probably be an electric steering pump

What to do when your quad stops in the middle of a water hole?

Need to get pulled out and there should be a drain hose under the air filter is a plug at the end of the hose pull out the plug. That would be a start. If water got in the carb, you might have to take out a plug at the bottom to drain also. Check inside airfilter to make sure it is dry. Hope this helped!

I was driving down the interstate and my car lost power. Rpms went down and died.. radio, air and everything else works will not start back but sounds like it is cranking.

Do you have normal compression, fuel pressure, and spark when cranking the engine ? Hopefully the timing belt did not break.

I hit a pot hole in my ford focus and it died. is there a saftey reset switch?

You can check the fuel reset switch which should be located either in the truck on one of the side panels,or behind the kick panel inside the vehicle on the passenger side, if it was a big enough pot hole it may have tripped this switch. Hope this helps.

89 nissan sentra won't start...

if you hit a deer , and the car ran hot, it could hvae damaged the engine . the rings and bearings. thats where the knocking is coming from. Check for compression using a compression testor. it is put inside the spark plug hole. While the engine is cranked. it should mark about 55 on the dial. Check all the cylinders one at a time replacing the plugs back as you go.
