MS 660 Starting Problem

[Lurcherman]

Looking for some advice from more machine-minded people than me.

 

2 days ago while cutting up a Palm, my (not very old) 660 stopped in the same manner as if it had run out of fuel. There was plenty in the tank, allowed it to 'rest' for a bit and it started again without a problem, then stopped and won't go again.

 

I've checked for a spark and there is one, the cylinder smells of fuel, but it's not going bang!

 

Before I attempt a carb strip-down, I was wondering if anyone has any other ideas?

 

Oh yeah, the tank filter is clean.

fuel blockage ,may be letting a trickle in but not enough to run it up

Sounds logical, looks like there's some s##t in the carb.

check the little wire gauze filter in the carb? HT lead broken? (occasionally the 2 broken bits may touch-i.e when checking for spark)

[Lurcherman]

Thanks to you both for the advice.

 

As it was anice sunny afternoon, I took the carb apart, blew everything through with the air-line, bolted it back together and away she went!

 

Thanks again.

might want to check the tank breather its a plastic pipe with a threaded screw inon top of the tank, in it take out the threaded screw and hacksaw a slot 90 degres to the threads then put back in u should be able to blow trough it.this being blocked give the same symtoms as running out of fuel,hope this helps
