Husky 365 special not starting

Gents, 

I need your help again.

My 365 has been on a mill, not much work in terms of total hours.

Never been a great starter but now nothing.

Fuel to plug.

Looked in through exhaust port. To my untrained eye piston looks ok.

Hangs and then drops, then hangs again on starter cord.

Have a spark, but not convinced it is strong enough. Any way I test? 

Am I barking up the wrong tree?

TIA

You've tried a new plug already ?

The ignition system needs to produce a spark that can jump the plug gap in the cylinder under compression (obvs!). In fresh air that means it needs to jump a bigger gap, say 3 - 4 mm.

 

With out appropriate kit,  Spud's advice seen on here many a time - is to take a plug and bend the outer electrode to increase the plug gap to a couple of mm. Cobble together a setup that holds the plug against the cylinder and pull it over on the starter cord and look for spark.

 

Worth checking the coil to flywheel gap and plug lead condition too.

If there is a spark there of sorts ( works of speed of rotation ) and good fuel to the plug it should at least fire, is there masses of fuel at the plug? is it just flooded? remove the plug, open the throttle fully and crank 5 or 6 times to disperse any excess fuel and try again with dry plug

Don't use the decomp, the valve lowers the compression too low IMO.

Heating the plug up with a plumbers lamp can help the saw start. 

Worth pulling the plug out, switch the ignition off, turn upside down and pull over hard to clear unburnt fuel. 

You can try the redneck, hold the throttle open and pull over hard, frowned by many as being dangerous but it can get a saw running if semi flooded....if you are careful!! 

If the piston is free of scores and it is clean when viewed through the exhaust port and it sparks well then the carb is left. Crud in the gauze strainer is the most common fault, holes fuel line a possibility where it pushes through the wall of the fuel tank, holed pump diaphragm and weak or stuck needle valve being possible issues also.

Plumber's lamp ? Def showing your age there now spud . Ask a modern plumber to fire up his lamp, he'd get his torch on his phone to light up your dark recess. emoji16.pngemoji16.pngemoji16.png

Spuds dark recess ? come on , this is a family show 😁
