Hard starting no fuel primer noise


Hi Jack:
You don't mention make or model so all I can do is relate 50 years of personal experience.
None of the chain saws that I have owned have had a fuel primer.
This has been (and continues to be for my Husky 266) my start routine. Current saws don't have compression release.
- prep includes fill fuel and oil tanks, check chain sharp and tension, bar tip lube.
- Ignition switch on
- Choke full on
- Throttle full and lock set.
- Pull starter cord *(266 takes 3 pulls, Homelite took 6) until engine fires. If I'm fast I can get the choke off before it dies, otherwise
- Choke off, Pull starter cord. Engine should start with 1 or 2 pulls.
Hope this helps.

My polan saw will start but boggs when given gas if you pump the throttle it will run at full throttle buy once it idles down it stalls


This is fuel starvation, replace the fuel filter in the tank, check the fuel hose up to the carb for signs of leaks, or cracks, if the carb has no anti tamper screws, screw the L screw out 1/4 turn to richen the mixture, if the carb has anti tamper screws you will need to get the special tool to adjust them.

It is running lean, they always need to run a little on the rich side free running, once the engine is loaded it will then need the excess fuel, it runs ok without the bar and chain because there is no load, start by replacing the fuel filter in the fuel tank, check the fuel hose up to the carb for signs of fuel leakage, replace if reqired, if the carb has standard adjuster screws, increase the H screw by 1/4 turn out ( anto clockwise ) this will richen the mixture.

Hi my huskey will only run for ten minutes and then cut out like it starving for fuel wats the poblem


Hi Matthew,
Check there are no kinks in fuel line.
The fuel lines may have be becoming airlocked.This can happen if the tank is run dry or the saw used at awkward angles for extended periods with low fuel in the tank.
Make sure that the air filter isn't blocked and the fuel filter is clean.
Check the throttle cable is operating the throttle plate in the carburettor ok.
Ensure chain isn't too tight.
The carburettor should be a tight fit on the air inlet manifold.
I had this problem with a hedgecutter. It turned out that the springs were broken in the clutch. If the engine doesn't stall immediately when the trigger is released and you notice the chain running slowly and the saw cuts out on idle, it might be the problem.

I have difficulty starting my Gardenline 49.3cc chainsaw. Please let me know what the correct starting proceedure is.


Genral starting procedure on a chain saw is as follows, put fresh fuel into the fuel tank, top up the chain oil tank,switch the ignition on, if the saw has a half throttle position on the trigger lock this, if the saw has a primer depress this as many times as it takes to 3/4 fill the bulb, pull the choke fully out, if it has a deco valve push this in, now place the saw on the ground with the chain brake on and crank the engine ( always have the saw body between you and the cutter bar,NO left hand starting, NO drop starting ) the engine will only fire once on full choke, do not continue to crank engine after the first fire or you will flood the engine, push the choke back in, crank the engine until it fires up and runs,release the chain brake and blip the throttle to release the half throttle device.

I HAVE A ECHO POLE SAW PRUNER. 25.4CC ENGINE. IT STARTS AND RUNS, BUT IT MUST BE CHOKED ABOUT 1/2 WAY. OR IT WILL STALL, IT HAS NO POWER, IT WAS LIKE THIS WHEN NEW. PURCHASED IN 07. TRY TO USE IT EVERY...


Inspect the jet screw (H and L) heads to see if the have slot heads or are 'D' heads which must be adjusted by a service dealer. Make sure to have fresh fuel mix with modern synthetic saw oil in the tank (50:1 ratio). Be sure to shake the container thoroughly each time just before adding fuel to the tank to prevent oil starvation. Inspect the fuel filter and air cleaner for plugging. Also, check the fuel line for decay or other problems. With slot-headed jet screws, turn both CW to stops (lightly), then turn each out CCW 1-1/2 turns. Start the engine and allow to warm up, then pull the throttle full on and turn H needle CW until the engine starts to speed up, but still 4-stroking. Proper adjustment is when the engine 4-strokes unloaded, but immediately 2-strokes when cutting. Release the throttle and adjust L CW so that the engine idles fairly well, but will still 'follow the throttle'. If the chain is trying to turn at idle, turn the idle speed adjustment screw CCW until the chain stops trying to move. Hope this helps!

I have an old McCullough chain saw 12 or 14 inch chain length. What is the oil to gas ratio I need to use? 50:1? 40:1? What do you recommend? I can't see any serial number or identifying numbers so the...


Run 40:1 using fresh fuel and a modern synthetic saw oil--mix it in it's own can and be sure to shake the can thoroughly each time just before refilling the tank. Don't mix up more than a gallon unless your business is sawing. You may need to deal with a plugged fuel filter if it won't start. The oiler button was intended to supplement the pumped bar oil when cutting thick/difficult wood. Normally, it is not needed. To start, set the choke full on until you hear a pop, then back the choke off about half way before the next pull (don't forget to set the fast idle button near the throttle--squeeze the throttle, push the button and hold while releasing the throttle). As soon as you squeeze the throttle again, that will release the fast idle, so make sure the engine is warmed up and the choke off before hitting the throttle. This engine will drive a 16" bar and chain, so upgrade when the original parts wear out. Hope some of this helps!

Hi how to tune homelite 330 chain saw carby, idle


Before adjusting anything, check the fuel filter, air filter, and muffler for plugging. Check the condition of the fuel lines for decay or other damage. Tighten all carburetor fasteners. Make sure you have fresh fuel mix in the tank. Does the primer bulb pull fresh fuel into itself when pumped? Turn both jet screws CW to stops (lightly), then back out CCW 1-1/2 turns each. This is a basic setting and should allow the engine to start and run. Start the engine and allow it to warm up, then pull the throttle full on. Adjust H needle CW until the engine starts to speed up, but still 4-stroking. Proper final adjustment is when the engine 4-strokes unloaded, but immediately 2-strokes when cutting. Release the throttle and adjust L needle CW for fairly good idle, but still allows the engine to 'follow the throttle'. Adjust idle speed screw so that the chain stops turning, but the engine will continue to run. Hope this helps!

Put a new chain on a macullock 335 saw it start


Remove the spark plug when it quits to check for good blue spark. If ok, squirt some starting fluid into the plug hole, replace the plug, and try to start. If it pops a couple of times, then you have fuel problems. Check the condition of all fuel lines for decay or splitting. Make sure the air cleaner and muffler are not plugged. Check the fuel filter inside the fuel tank for plugging. If everything looks ok, then it is likely time to clean and re-kit the carburetor. Basic setting for both jet needles is 1-1/2 turns CCW from CW stops (lightly). If everything is in order, it should start and run. Allow the engine to warm up, then apply full throttle and adjust the H needle CW until it picks up speed, but still 4-strokes. It should immediately start 2-stroking when cutting. Allow to idle and adjust the L needle so that the engine idles fairly smoothly, yet allows the engine to 'follow-the-throttle'. Hope this helps!
