Craftsman 358.352070-14 chain saw start problem

Either you have a air leak fuel inline or at fuel tank or a plugged up carb- sour aged fuel or foreign debris

look for gas tank vent. if clogged it will cause a vacuum in the gas tank and not let gas flow to Carb.

this new gas is a carb killer you will need a new diaphragm for the carb and there is a little screan next to the needle and seat that can be cleaned. about a 5.00 repair if done right.. use marine gas

It may well be gummed up in the carb from the stale fuel, you will have to remove and clean/ service the carb.

There are very few things that will increase fuel consumption, blocked spark arrestor in the muffler ( metal gauze in the exhaust out let ) blocked air filter, part blocked exhaust port ( remove the muffler and check ) if the fuel tank is seperated from the chain oil tank with a gasket you may have a leakage between the two ( is the chain oil getting thinner and smell of fuel, other problems may be in the carb, leaking inlet needle, this will require a carb pressure test to prove, if you have a small bulb pressure tester, remove the fuel hose from the carb and connect the tester, put approx 2 psi in, the carb should hold this with no pressure loss.

the reason is you need to clean out the carb,if they dont get used much the oil/gas mixture turns to a varnish in the small carb ports and fuel can no longer get thru the carb

Clean carb. Pull apart and soak in carb cleaner. Blow dry with air nozzle. Make sure air filter is clean and plenty of air. Make sure spark plug is not gapped wrong and running to hot. Make sure oil/fuel mixture is accurate

Fuel oil mixture is deturmined by the brand of mixed fuel you use, not the machine. The machine will state what it's recommended oil brand states. Example a stihl chain saw will be 50:1 with stihl oil but if using echo oil it would be 35:1.

Hi

An engine needs three things to run(fuel and air mixed together in the correct proportions,compresion of the fuel/air mixture and ignition).Make carb adjustments,check the compression and the spark from the sparkplug.Priming the engine(put some gas into the sparkplug hole).Try to start the engine.If engine is running only the gas from the cilinder,the chain saw has a fuel delivery problem.Disassembly the carb and clean the inner parts.Check the fuel and air filters,fuel hose and gas tank ventil.

good luck!savumihai71

Hi lwhssh:
Suggest you drain the fresh gas/oil and add a fresh batch but first add a gas stabilizer to your batch of gas/oil in the storage container. You will probably still need to use starting fluid for a few times When 2 cycle engines sit for a long period of time, the gas/oil mixture undergoes a change and tends to leave a residue on the delicate parts of the carb. The gas stabilizer will help that.

I always do the following for 2 cycle engines when I put them up for the winter. Empty the gas container on the device and then start it to use up any gas left in the fuel lines and carb. this keeps any residue from forming.

Hope this helps Good luck Loringh PS please leave a rating if appropriate. Thanks
