Make sure the air filters are clean. Secondly blow out all the dust and dirt with compressed air espessually around the cylinder. Some of these units have a cutout swich to protect the engine when they get hot.

My Husqvarna 351 starts then stops after 1-2 seconds


Once the saw cools down will it restart and run fine? There are a couple other solutions that are not directly due to carburation. The first two solutions above are definitely your first options.

1. Ignition Coil: Highly unlikely, but possible. I seen some where they get hot and run fine while cutting, you shut it down for a few minutes for whatever reason and it won't restart or starts and stalls.

2. Crankcase Air Leak: We started to see more and more of these issues. There are a couple of quick ways to test this if you do not want to pay a shop to do an actual test. You want to do a cold test and a hot test. With a half tank of fuel, start the saw up for the first time of the day. While the saw is idling, turn the saw sideways from right to left, do this slowly, listen to the saw idle, if the speed changes by increasing or almost stalling, you have a crankcase air leak. Most bad air leaks won't be noticeable until the saw has gotten hot and the aluminum crankcase starts to expand a bit. Do the same thing once the saw has gotten hot. If this happens when it's hot, chances are that it won't start or starts and stalls until it cools down and everything retracts.
Test Results:
Sporadic idling when cold: Most likely just the oil seals, fairly inexpensive repair.
Sporadic idling when hot: Most likely crankcase itself is leaking, requires a complete crankcase gasket replacement. Can be fairly expensive to repair.

Bosch Table saw sparking and lacking power.


Forgive me as I'm not too educated on the configuration of this saw but when I heard you mention armature replacement it made me think....are there armature brushes that are worn out. I know a lot of my angle grinders spark, get real hot, and smells like burnt plastic when brushes are worn out. Are there brushes on this saw? Just a thought.

Chain saw ran for a few minutes became hot with little smoke and now will not start again.


It could get hot and not start if the saw was quite dirty because it relies on air for cooling and if the fins can't get enough air around them it would heat up and not start. Another thing is if some one did not use the correct gas oil mixture it would get hot and score the cylinder lowering the compression causing it to not start.

The saw is a 385xp. We have changed bars and chains numerous times. When sawing the bar gets hot enough to fry an egg and the chain stretches out. Onlynable to saw a minute or teo at the time. bar gets...


Overheating the chain/bar is usually caused by insufficient oil getting to the chain, but can be caused by the chain being too tight to begin with (you should be able to turn the chain by hand), grit in the chain groove, or a poorly sharpened chain. The saw has an oil volume adjustment screw on the lower part of the case near the chain return area. Turning it CCW should increase oil flow. Oil volume can be judged by running the saw tip at speed near some cardboard for a moment--it should throw off a thin line of oil. Chain sharpening condition can be judged by the sawdust residue coming from the cut--if a powder-like material, the teeth are not sharp or are improperly filed. You should not have to bear down excessively on the saw to make it cut quickly. Hope some of this helps!

Chainsaw starts only stays running on full throttle for about 1 min. then stops. seems like running hot and wont't start again


Hot is usually caused from spilling mixed gas with oil in it when filling the tank. This usually runs down over the saw and the sawdust sticks to it. Over time this will plug up all the cooling fins on the cylinder head. This can cause the gas in the tank to get hot. I've seen some saws even boil the gas. Eventually it seems that the gas tank cap's vent usually gets plugged up over time and you can build up a lot of pressure in the gas tank. If when you take the gas cap off you hear a lot of pressure releasing you should probably get a new gas cap. If this is happening it is probably enough pressure to flood out the carburetor and cause the saw to die. It's worth cleaning your saw to get any excess sawdust/oily residue off so your saw will cool better. There is also a fuel filter down inside your gas tank. You will need a stiff wire with a hook on the end or maybe a screwdriver to reach down inside the tank and find a small fuel hose and pull it out. The filter will be on the end of the fuel line. Change it out.


The default setting for the H and L carburetor jet is usually to turn them in all the way till they stop and back them out a turn and a half. You need to set the mixtures for the carburetor. You will find a Low and High adjustment screw. turn the low adjustment screw out. You will notice that the rpms should start increasing. keep turning it out until the rpms start to drop then turn it back in a quarter of a turn. You may need to readjust the idle speed so the chain doesn't turn during idle. Do the same for the high adjustment screw.

Hope this help. Happy timbering.

My table saw stops after a minute or two i replaces the capacitor and still does the same the breaker pops out


This means it's drawing high amp. Could be just packed with saw dust, getting hot. The breaker is probably thermal. Clean it up good. If it still trips, check for name plate current on motor and test.

Table saw capacitor heats up and explodes.


The wrong capacitor for one thing. There are starting caps and running caps. The starting cap is in the circuit for only long enough for the motor to get up to speed. If you have a Leeson motor that has a start and run cap then the run cap may not be the correct on. If you have a start cap blowing out I suggest you check the centriifugal switch in the end of the motor. It may have welded the contacts shut. In any case, I would take it to a motor shop .
