1995 app Suzuki LTF250 Starting Problem

2 posts in this topic

I use my ATV for harrowing a horse sand school. Last week engine stopped 15 minutes in use. Re-started twice but just loss power within seconds. Finally would not re-start.

Stripped and checked carb. Replaced plug. Will not start - any ideas?

Using 4wd and mid range gear. It has always started well with charged battery.

You first need to determine what is missing from the equation; spark, fuel, or compression. Take the plug out, and ground it to the motor while turning it over, look for a strong blue spark. If you have spark, see how well it starts with starting fluid. If it fires easily with the fluid, you may have a fuel problem. You may just have bad gas, or it could be a blockage in the fuel system, a failing fuel pump, or bad vacuum signal line to the fuel pump. Take the line off the carb coming from the fuel pump and turn the motor over, see if any fuel comes out. If you can't find a problem with the spark or the fuel delivery, then you may need to do a compression test. I would certainly get yourself a good repair manual to start.

      A week ago I could not even get close to starting it. But now I adjusted the valves (exhaust valve was not closed). i got it running but would not run without choke. i adjusted the float because it was to low tried starting it up again and it would not even start. So i went back and looked at the valves and the valve was now open again so i adjusted it and it started right up and ran perfect without choke. So i put it all back together thinking it was ready to go. Started it up and let it run for a little bit. i turned it off and tried starting it again there was NOTHING. took it apart and there was 0 compression and the exhaust valve was open again. I am completely lost need help PLEASE!!!:aargh:
