372 XPG not starting

[polarismd]

Hi,

 

I have a problem with my Husky 372 XPG.

 

Whilst cutting some oak it died and stopped.

 

I checked fuel and all the obvious and changed the plug, the dealer did not have the 7a plug so gave me a 6a....

 

I have a spark but it seems weak. Should the 6a work or is there too much resistance? She won't start no matter how I try.

 

I put a new coil in and still nothing.

 

The dealer says it should not make any difference but I could do with some advice.

PS - Dealer disposed of 7a for me so I cannot try it in case it was the coil.

Have you got the right gap between the coil and the flywheel magnets ?

Sounds daft but have you got the heated handles turned off as i had found it easier to start but guessing you haven't got them on in this heat lol

Best pull the muffler off and take a look at the front side of the piston, vertical scores are bad news and if it looks like a wet fish belly, all is good.

 

After pulling it over, is the plug wet - if it is and you have compression then the problem may well be spark.

 

The 6 plug is a different heat plug, both will work but it should be the 7 plug for correct use.

 

A running engine needs compression, fuel and spark, it is just making sure you have all three and if you have, then it is a case of a little more diagnosis!

Hi,

 

Looks like compression then, new carb, nice healthy spark.....how is the best way to check compression? It feels no different to before and no smoke was apparent when it stopped.

 

Anyone suggest a good repairer in the East Midlands?

The only true way is with a compression tester. Easy and quick.

 

A simple gunston hi gauge will do. Don't need a fancy all singing all dancing one for chainsaws. Or a local friendly garage.
