Sounds like no timing advance. Will seem to go well up to about 55 or 60, but will run flat or even slow down above 60. Follow shop manual procedures for verifying timing advance operation. If you watch the timing mark with a conventional timing light, you will most likely discover the mark will not move when you rev the throttle. If this is the case, you must replace the electronic timing pickup or module. Consult shop manual for the correct procedure.

Why does my ATV bog down and die when I keep the throttle wide open?


If you are lucky, you might just need new fuel filter and the fuel bowl cleaned out, and maybe new air filter. If not so lucky you need carburetor rebuilt. Backfire is usaully caused by engine running too lean ( too much air for the amount of fuel present). Fuel bowls get gunk in them and the fuel needles and fuel jets get varnished up. The accelerator pump gets worn out gaskets and/or bellows and doesn't give the right amount of fuel mist when you accelerate.

Chokes and Dies when cutting


Adjust the choke or carburetor. In case your chainsaw stalls when the engine is idling, ensure that the choke is set properly. To do so, first try releasing it to adjust it, and then move the plate and tighten all screws once again. To loosen any grit, spray carburetor cleaner spray on the choke's shaft. The carburetor may also need to be adjusted; consult your owner's manual which will guide you on resetting the idle mix screw.

The accelerator pedal on my 2000 Saturn SL1 or SL2 stuck down at speeds over 65 mph while driving last night. It's in the 20's here in Wisconsin, and the car was sitting in the driveway for d


you don't have a choke.
Could be the linkage hanging up for sure.
Have it checked by a pro ASAP.
Although it's kinda easy to replace, its easy to go wrong if you don't know what you are doing and safety should always come first.

2003 yz 250 starts and idles but runs rich and bogs as soon as the throttle is applied


Hi, Anonymous and the usual suspects are:
1. Throttle cables misaligned or misrouted.
2. Damaged or restricted fuel tank venting system.
3. Intake system air leak.
4. Vacuum piston malfunction.
5. Accelerator pump leaking or no output.
6. Plugged bowl vent or overflow.
7. Fuel level in bowl too low.
8. Restricted fuel supply passages.
9. Plugged jets or passages.
10. Worn or damaged needle or needle jet.
11. The enrichner valve not seated or leaking.

Old chevy 235 six cylinder, when cold it falls on its face


Question, does it stall, or bog? A few things come to mind. You say the carb. is new, what is the cfm of the carb.? Could be too much carb. for the cam. It could be a problem with the accl. pump on the carb. dumping too much fuel on take off. Have you checked the fuel pressure at the carb. also? You say you checked the timing and vac. advance, but is the timing set high enough? Usually this is a sign of too much fuel being dumped. If you have the chance, try another carb. Let me know.

Hard drive short-circuit


Try taking the drive out of your computer and placing it in another computer as a "slave". Allow the other computer to boot up and seeif it recognizes your hard drive.

If it does, access your files that you need and copy and paste to an external hard drive till you can replace your computer with a new hard drive. It's worth a try.
