Setting hi lo on 235 husqvarna - Husqvarna , No.455 Rancher, 20" Gas - Powered Chainsaw

Vincent, uasually if you back the hi and lo screws out 1 to 1 1/4 turns it will start and you can adjust as need to get it running perfect.

Check fuel supply, proper plug (resistor) compression 120 to 145 lbs. If saw will not run have the ignition tested with a 3-point spark tester.

before replacing the carb remove the muffler and run it the muffler has a screen inside that gets plugged up with carbon then replace the fuel line from the filter to the carb they crack and **** air instead of fuel

if you tighten the panel for the bar and chain too tight it pulls the bolts out slightly out of the chassis of the body. that is why it isnt oiling properly. i had a 235 and that is what happened to mine. what you could do is file down the raised plastic where the bolts enter the body and that might help.

hi there

the base settings for hi and lo are 1 & 1/4 turn out from lightly seated

but make the hi setting just a fracrtion richer at top speed no load it should putter or 4 stroke slightly and the lo one should be about right buyt should pick off nicly when you stab the throttle quickly with no hesitation

note do not sett hi mixture setting to lean 2 top nol load or when you place it under lood it will lean out further and destroy the piston and rings

find L on your carbruetor and turn it clockwise 1/4 turn to see what difference it makes
it should begin to idle by itself?
zama carb. 1 turn out from closed
walbro 1and 1/4 from closed settings are only preliminary

hi charlier 421

I think the small holes from the Venturi wall of the carb are clogged.To clean them you need carb disassembly.Near the needle there is a tehnological cover,under the diafragm(fuel pump).Taking off it you will see some small holes maiking conection with Venturi wall.Used ompresed air to clean them.
