1 Answer

Stihl MS 260 Pro wont run wide open or idle.

Saw is like new. Only 2 tanks off gas threw it. Had carb. cleaned, still the same. Know dealer says I need a new carb. abd they cant find my warrenty. $100 for a new one, on a already over priced saw. The old Stihl were great saws. My dad has a 28, no trouble in 18+ years. Think the new ones are ****!

Hi brandon First change the sparkplug with the same heat range,Check and clean the gas filter with compressed air.Remove the carb and very carefully disassembly entirely.Check the gaskets and the diafragms.At the fuel pump side there is a fine screen(clean it).Check the needle,the spring and lever.Unlock the screws L and H(note how many turns are they).Put the corp of the carb in a special clean solution for 12 hours and then clean it with compressed air(something is clogged there).Put all back together and try to start the engine. regards savumihai71

Mccullugh MCC1840 18" chainsaw. Gas pouring out bottom of saw. How do I get to the gas tank?

The fuel tank is part of the rear handle support body.
The fuel line to the carburetor goes into the top of the tank.
You will also find a return line from the air purge primer bulb. More than likely, one of these lines has broken or cracked. Gain access to some of the lines be removing the recoil assembly.
1) Remove the Air Filter and Filter Cover
(which you have already done)
2) Remove the recoil assembly to gain access to the primer lines.

My saw barely uses half of the oil tank with a tank of gas when new it used almost all of it and even sometimes ran out

1. clean bar & saw - checking oil holes, groove on bar; oil outlet on saw - may be partially blocked - a fine wire may assist with careful clearing.
2. if cleaned replace bar/chain and test for oil flow.
3. drain oil and check if there is a filter, clean/replace filter and clean out tank.
4. see step 2
5. If still not flowing - check for manual adjustment of oil pump.(May need to be advanced)
The next steps depend on your own abilities and experience as to whether you want to further investigate or approach a reputable dealer to see about repairing or replacing oil pump and or associated oil line(depends on your brand/model etc).

unleaded fuel is notorious for going stale,and it can leave a resinous coating in the carb-try running the saw on half choke with new gas and less oil eg 50 to 1 for say ten minutes,this should clear the gunk out-if this does not work,you have two choices-strip and clean the carb,or adjust the H (high) scew on the carb anti-clockwise by a quarter turn a time till it revs out full bore-good idea to remove the chain and wear ear defenders when adjusting-and always use a chainsaw at its max rpm,or you run the risk of "kickback"

Saw runs good when you prime it cant get it to get gas from tank

Sounds like you have a plug between the tank and the carb. I would change the hose between the two and clean the tank as well as the carb.

Cant figure out where fuel lines go on mccullogh chain saw

Fuel lines: one comes from the tank...has a filter in side the tank...runs up to the intake of the carb... you can tell by hooking up the lines to the carb, and put one into a gas supply... press the prime bulb... if it pulls gas, thats the one to hook into the tank...if not it 's the other... there should only be two lines a fuel supply and a return pressure line. Clean the air filter while you've got it apart....
