SOURCE: chainsaw won't keep running except on full throttle?

Running at full throttle but not at idle would probably be caused by not enough air getting through to the cylinder with the fuel. This could be caused by blocked/dirty air filter, air leak or worn/damaged piston or cylinder. The higher the revs are the less air to fuel ratio is needed so it will run at these speeds. First check your air filter, if that is fine take the spark plug out and examine the inside of the cylinder. You will need to check here with the piston down. If you want to be a bit more thorough you can remove the exhaust and check the piston face and inside the cylinder from here aswell. You don't want to see any scoring or solid lumps of anything in here. While you have the exhaust off give it a few firm taps to make sure there is no major carbon build up and clean the spark arrestor if it has one. The arrestor is normally a small gause found on or near the exaust outlet pipe. If that all seems fine then get some soapy water and squirt it around the carb gaskets and pipe that runs from the carb to the cylinder. If you see bubbles appearing here when the machine is running then you have air escaping and it will need investigating. Failing this you could have worn piston rings or crank seals. Ideally to test this area you need proper pressure testing equipment.

SOURCE: blower wont run at full throttle

Start with the spark plug it is the easiest.

But sounds like the carbourator is dirty, Probably fouled with old gas varnish. When it is idling give it a little throttle, flip the choke on and then full throttle. If it goes full throttle and doesn't conk out, it is a fuel issue.

Good Luck

Ive found that the carbs need the coreect airflow to work correctly.If you dismantle the carbs and make sure all the air passages are clear from blockages.Ive got an early gs550 in a gokart and it had no airbox and it was doing the same untill i covered some of the carb throats with my hand and then she would rev her nuts off.if you take any air screws out mark there position and count the turns out to place them back in the same place.Im making my own manometer using some 4mm hose a garden sprinkler 4mm attachment and a cheap airflow meter from cip1.com.

running the correct air box is crucial and the filter must be clean.

hope this helps David New Zealand

SOURCE: Maytag dryer timer keeps running

Your dryers timer contacts have fused to gether.
The only repair is to replace the timer.

If you've never replaced the timing belt or chain,That would be my first thing I'd check is the Timing belt or chai, just aline the timing marks on crankshaft and then look at the position on the distributor to see if it's pointed in the #1 firing position .
