SOURCE: Snapper SS312 weed eater. Cranks when primed but won't run

I am sorry to say this, but the compression for that type of engine should be atleast 120 psi. Remove the muffler and look at the cylinder, it is scarred beyond repair.

SOURCE: Can't get weed eater started. Have an older weed

This is a common problem on older Poulan models. Press the primer button 10 times and pull the starter rope twice, then pull the spark plug and examine it. If the plug is wet that means gas is definitely getting to the combustion chamber. Next thing is to use a compression tester. If you do not have a compression tester but have an AutoZone anywhere near you, you can get a loaner from them. Screw the compression tester into the plug hole and pull the start rope 4 times. If the tester reads anything below 90psi, you have a bad ring and will have to take the motor apart to clean the piston and ring or replace the ring.

Keep me posted on what you find, ok? I can walk you through the procedure to replace the ring if necessary. Good Luck!

Sounds like the clutch has taken a long trip south. If the clutch pads are not wore out, try some wd40 on the pad hinges.

Why won't my McColluch weed eater create a vacuum

Did you check the muffler exhaust or spark arrester, to see if it is clogged from using to rich a oil/gas mixture ? Did you replace the diaphragm in correct position ? Find a new carb online, possibly ebay ?

New 5 hp LEHR propane outboard motor requires 4 pulls to start. Not reliable at low revs, misses and stalls.

You need to adjust the needle valve that controls the propane into the carb, Lehr website has videos about this, its real simple, you need to add more fuel than reset your idle speed, mine needed the same thing, these motors need adjustment at time of sale and many places do not do it.

Which trimmer starts the easiest and is built to last the longest? I'm considering the Honda 4-cycles and the Lehr propane models among others. Thanks...

Be careful on the 4-strokes...the engines often last a long time, however, the weak point is still the carburetor, just as the two strokes were. The propane ones are a good choice, as they burn really clean, and your engine will run a long time due to the lack of contaminants in the oil. If you didn't go propane, then my suggestion would be a Stihl trimmer; there's a reason that most of the contractors and road crews use them; they will take a beating and last forever. Do yourself a favor, and search for problems for the kinds of trimmers that you're looking for on FixYa. You'll find that some brands are listed OFTEN, and some don't even have a category due to lack of need for one. If you're looking for more budget, believe it or not, MTD(troy bilt, bolens, etc) has a decent 32cc trimmer that's cheap with loads of power for its size. Hope this helped you a little. I won't give you specific models, as most of them are the same engines with small variations. I can tell you though, to stay away from the ones by Ryobi, Honda is a nightmare for repair, Homelite is a disposable machine, as well as weed eater and poulan.

Engine will not start

yes, that gas treatment stuff meant for this purpose is great stuff! you can get it in any hardware store or small engine repair place,...just mix some into your gas tank, pour it into your little ryobi thing and let her sit, problems when you go to start it up months later
