Husqvarna "Chain Saw - 16" Bar, 3 Hp Questions & Answers
My husqvarna chanswar want start I changed my spark plug and the petrol and still want work ?
Forget checking the spark by grounding the plug to the engine. This is both dangerous and does not tell if you have enough spark under compression.
Start by performing a secondary compression check, without proper secondary compression, the unit will not start. You need between 115 - 165 psi.
If compression is good, check the spark with an inline spark tester. Set the gap on the tester at 6mm. If you have a blue / white spark, ignition is good. Make sure the ignition is gapped .20" from the flywheel, more or less will retard or advance the timing of the saw. Make absolutely sure you have the manufacturer's recommended spark plug. If it calls for a resistor plug, it MUST use a resistor plug to operate properly.
If you have compression and spark, check fuel supply. Rebuilding modern carburetors is not recommended. They have very small fuel flow holes (due to emission) Replacement carbs can be purchased for under $100.
WHAT IF I PUT GAS WHERE THE OIL GOES
if you mean where the chain oil lube goes then you could have a fire if any sparks occure ! If its where a seperate 2stroke oil feed should be then you will not lubricate the engine internals and sieze the engine ! Just drain out and fill with oil , 2stroke will need to be bled on the side of oil pump !
Why husquavarna concrete saw wont idle down
Have you checked the throttle is returning to tickover on the carb ? cable sticking ?
If it is on tickover and still high reving then you could have an air leak after the carb , check the intake manifold , crank seals could be worn and this will let the engine rev by its self ! fuel mixture correct as if its 2stroke a lean mix can do this as well ! ??
Change the water pump on a 90 hp Johnson outboard
tilt engine and remove all bolts that hold gearbox to leg , put box in vice and remove impellor house and remove impellor , check all holes and seals below housing for damage etc , if impellor has broken up then check water down pipe is clear , you can run engine with box off and put hose to down pipe and turn water on and run engine for 20min and see if engine cools b4 you fit box so you know no blockages etc ! as you fit impellor rotate clockwise as you push down on housing , bolt up and fit box and as you do turn flywheel to engauge driveshaft ! Bobs your uncle ....

I would find a lawn and garden shop that repairs chainsaws. Take your saw there and they should be able to get you the correct file.

There is no problem as long as the bar is the right bar and the new chain you use is the right pitch for the sprocket that is on your saw.

No problem at all. Just need to make sure the two studs attaching the bar to the motor head fit correctly. Of course, the former chain is now too long. Either have a saw shop make you a 'loop' to fit, usually $1/inch of bar=$16 for your new setup, or try a prepackaged chain labelled for the 16 inch bar. I recommend the former, because then you get an expert to look over your new setup for you. Shop chains are usually better quality, always fit correctly, and cost no more, often less, than department store chains
