Help setting up Husky 263 xp

[THORIN CORLISS]

Bought a 262xp as a basket case, so far have replaced piston, ring, cylinder, magneto, crank bearings and seals, rebuilt carb, new 20" bar & chain, fuel line & filter, and lastly air filter and spark plug. I can't get the darn thing to run, it'll start and maybe rev up but then dies and wont restart. After that it's a real PITA to get to start and if it does it'll fire, idle high then die. Any ideas / advise would be great. Thank you.

What carb does it have, Walbro or Zama?
Sounds like the carb isn't adjusted properly.
Were you able to pressure test the saw?

i would pressure/vac test it before doing anything else

Compression is 110psi after 3 pulls

Here is the tag off the saw.

That’s really low, do you have another running saw you can check your gauge with? As Cus stated above, pressure and vac test first, then move on to compression test.

thats a very early serial, looks like a decent survivor. erratic starting, going to a high idle and dying says air leak to me, but its hard to say. very simple saws to pressure test if you have the equipment

Can you pull your muffler and post a picture? You definitely have a compression problem for a 262. As stated more than once, you need to vacuum check that case. Hope you get it worked out, 262's are nice cutting saws.

replaced piston, ring, cylinder

and only 110 PSI something wrong

could be just a bogus gauge setup? and at least for me, it usually takes at least 4-5 pulls to get the gauge to stop climbing. could be aftermarket cylinder with .060 squish haha.

Very possible

262's deserve oem or meteor at least!

Ok I'll pull muffler in the am, I thought that comp. Number a little low.

Il try and set up a vac test also. What parameters should I be looking for?

Make sure the flywheel key isn’t sheared, it’s an easy one to shear.

Shearing one will maybe allow starting, but it will run like crap, not idle, flood out, etc...

Quick and easy check is to pull plug, rotate till you see the piston at TDC, and see if the flywheel magnets are lined up with the coil.

 

[THORIN CORLISS]

Ok thanks, I will check and verify that also

Hold - 7 psi forever, slowly dropping is ok also.

 

[THORIN CORLISS]

Ok thanks

Ok, well that was it. Took it apart and found that there was almost nothing left of the key and the crank slot was a little wallowed out. New fly wheel on the way (outch) pulled one off my buddy's saw and tried it, works great!! What a monster!!!
Thank you all.
