How high is the "pop up"

 

Sounds like it's coming along , glad you saved the cylinder !

Just put the short block back together with ancillaries and will try and post tomorrow mate.

What's it going to take to get martin on his lathe ??

 

Lots of beer Matty ;-)

spud, I've got a husky 61 (which I've just replaced with a 560xp) that won't run on its side and refuses to be tuned. I sent it to a local guy who put a carb kit in it when it came back it ran ok for a morning but then wouldn't tick over. I altered the tick over screw and she ran all afternoon. now she won't stand any revs as she just bogs down and conks out. I took it back to the chap who can't make head nor tail of it and he said sell it as a non runner. have you come across these symptoms before?

Cheers

Have you tested the fuel line? TBH, I would also do a pressure check on a saw of this age as the seals and inlet/impulse can start to leak!

 

The carb should be cleaned and the lack of high speed revs is most likely a fault in the high speed circuit, tank breather or fuel line issue.

 

everything is fixable:thumbup:

Yes, how high is it Martin??? About right I think.....now:lol:

 

Hows the back?

Back is starting to get there boss fingers X Friday

The chiropractor is working on my left leg as well as my back

If she frees the leg like she done my Back

I can't see why I can't be in full swing by the start of feb

Whoop whoop as u know mate iv looked forward to this for quite a while

 

As for the pop up was it to high or low :lol:

thanks spud,

although we haven't tested the fuel line there is no evidence of leaks in the form of fuel. he cleaned the carb when he fitted the new carb kit. i'll suggest your other potential causes to him

Re the Husqy 61, is this the early saw with two part ignition system, or later type with single ignition unit and orange top cover??

Started up on the 560XP, sorted the damage the disintegrating stuffer caused and have modified the transfer lowers and channel. From the standard image you can see the bulges where the exhaust bolt is supported and a casting flash nearer the upper transfer.

 

I will clean and extend the uppers and also modify the lower skirt of the cylinder by the transfer where it pushes in to the crankcase but will wait for the bottom end to arrive as I don't have it yet.

 

The support bulges have been reduced, the flashing smoothed and have smoothed and flowed all the angles in the lowers. Flow doesn't like angles as it caused turbulence and this slows flow!

 

Next job is the exhaust port - this has a very flat lower edge so have to be careful it doesn't snag the ring so will be conservative with the port shape, may drop the lower edge and bevel it well!
