Ok I'm fairly handy with engines but this has got me stumped (no pun intended)
My sisters b/f bought a
Husqvarna 265RX Forestry Brush Cutter
They retail at £743.99, he got it off ebay for £100, the guy told him he'd get £4-500 return if he resold it yearight, anyway I think the reason it was cheap is cos the fecking thing wont start
Right, I got a new plug , correct gap, good spark.
I've adjusted the High and Low carb jets from 3/4 out to 1 1/2 out at 1/8 intervals.
The mix is 30-50/1 2-stroke depending on what you use it for (I put 40/1 in)
I take the plug out and have a good clean fine spray of fuel, no spitting.
The kill switch was a bit finiky but I've fixed that (and besides , I'd have no spark if it was that)
I've checked compression, seems fine.
I've overhauled the carb and cleaned the jets.
The piston isn't sticking or ceased as she pulls over fairly easily.
The first time you try to start it the engine will "Run" (not start but the piston kinda rolls as if it's about to start), then for the rest of the day it simply turns as you pull the cord.
Now I'm thinking it's either the diaphragm in the carb has hardened or possibly split, but that would effect the fuel output which seems fine.
The only other thing I can think of is the timing is out, as far as I know it's not eletronic ignition so no points, but it's possible the flywheel has shifted somehow.
If the piston isn't at the top when the spark hit it wont ignight, other than that I really con't think of what else could be wrong
Any ideas?
