Has it enough compression ? because i have the experience it have a questionable closing system for carburetor air filter it is not always fully locked take care to close it replace parts if its not as soon as this problem is there or its to late , on the way it should but when it is not good closed it leaks in much cases and the piston had often grooves by polution from graveldust it can have lost compression by it first to do is control the piston.
In the event that all of this is not the subject the tank airiation and fuelhoses to control.

RUNS AND QUITS


You could try replacing the ignition coil. If it's failed, then it may run ok for a few seconds, but as it heats up it fails. Trying to start again immediately will be too soon for the coil to have cooled down. Leave it a few minutes to cool down and it will run again, but only for a few seconds again.
Hope that helps

Sounds like fuel starvation, always start with simple things first, replace the fuel filter in the fuel tank, check the fuel hose up to the carb for signs of leaking.

I have a Homelite 330 chainsaw that I bought in 1990. It barely gets used and I have never done any maintenance to it. The problem is when I start the saw it runs wide open for a few seconds and then...


I will share with you the most common problem experienced with the model 330 with that type of symptom. Due to the anti-vibe system design of this saw, the carburetor is connected to the cylinder by a rubber "boot". Should this boot become damaged it creates an air leak and will cause the saw to overspeed and generally not run well at all. While there are other causes of this symptom, too many to list here, this is the most common with that model. Hope this gets you in the right direction.

Poor gas in carb it starts and runs for a few seconds and then quits


If the saw has a primer bulb keep pressing this, the bulb will pull fuel from the barb and dump back into the tank, now drain the tank and start again.

Husky 51 runs for a few seconds dies than when i open gas cap and put it back on saw runs a few seconds than dies


Check the fuel filter for plugging. Check the fuel lines for decay or other damage. If the cap vent was stalling the machine, removing it should allow about a minute or so of running before it quit again. Hope this helps!

start with the capacitors. you may have 2, a start and a run capacitor. also you can spray the inside of the motor with WD-40 and turn it by hand until it feels loose.

Husqvarna 235e will not stay running


Take the saw back for warranty service. We have a Husky #435 that had starting problems when new last year--warranty service replaced the ignition module the first trip, then a little later, they replaced the carburetor--it has worked very well since. I suspect that Husqvarna has had problems with our ethanol blended fuels. Hope this helps!

Poulan 2025 chain saw, I prime it cain saw, set the choke, give it a pull, it runs for a few seconds and quits. where do I start


Probably with the carburetor, fuel lines, and fuel filter. Check the air cleaner and muffler for plugging. Make sure the fuel lines are not decayed or damaged. If the above does not help, then remove the carburetor, clean it with spray carburetor cleaner, and check the two diaphragms for hardness or any damage. Check the impulse pumping passage behind the carburetor which may be plugged or is open to the air. Any fault with these pulsations will prevent the carburetor from pumping fresh fuel into itself while running. Hope this helps!

Doesn't want to start. Replace carb and ran for few seconds, Make you think that it is not getting gas, but pouring gas into spark plug does not help and drying spark plug dose not help. Spark appears...


The spark should be blue and snappy. Try a new plug--any help? If not, it may need a new ignition module. Check the flywheel magnets--they should be quite strong. The module gap with the magnets underneath the poles should be about business card thickness. Check the air cleaner and muffler for plugging. Hope this gets it running!

Engine starts and runs a few seconds and quits


It sounds like your carburetor needs cleaned. If you started it for the first time without emptying the old gas, you may have had dirt particle's that had settled at the bottom of the tank. This would explain why it had ran the day before. If you need further assistance on how to clean the carb., just let me know.
