Cant keep my mccollough airstreamIV running please help!!!!!!
Every time start it with ether, it starts and then it dies. I checked the spark plug and put tIhe right mix in it ,but it still dies and acts like it doesn't get gas. I also checked the air filter and sprayed carb and choke cleaner in it (nothing).
Re: Cant keep my mccollough airstreamIV running please...
First of all NEVER use ether on any 2 stroke engine . it sounds like u have a carb thats clogged but be for u do n e thing u r going to have to do a compression test on the unit .it needs to be a min of 130 psi if its below that u need to replace the piston rings and cylinder head . u might wanna get a new one if thats the case! when u have a 2 stroke its very important that the gas mixture is perfect and u have to shake the gas be for u use it . that will make the unit last 4 a long time ehter will kill the machine fast

When it shuts off pull the plug wire and using a spark tester see if yo still have spark. If you have no spark you probably need a new coil. If you stil have spark put the plug wire back on and spray a little ether *(product usually called "instant start") and see if it starts momentarily. If it does your carb is in need of a cleaning. Most have tiny screens that plug up over time. Replacing this screen is recommended. Cleaning almost never works!
check age of gas. Cannot be more than 30 days old.
Make sure to use fresh gas w/synthetic 2-cycle oil @ 40:1 ratio
(1 gal.) Gas to 3.2 oz. Oil). Do not use old or stale oil/gas mixture. Always
use the proper oil/gas mix. If you do not, your engine will suffer rapid,
permanent damage.May need to clean or replace carburetor.
check and make sure its getting fuel. when trying to start, spray some engine starting fluid in spark plug hole. just a little bit. replace the plug then try to start it. if it starts then quits then its a fuel problem. fuel not reaching engine. good-day !
I don;t know what engine is on your mower but if it has the self contained electronic ignition coil I have seen happen on several engines. It would run good for several min. then the spark just stops . And it will not spark again until it sets and cools . Just make sure it is the ignition that is not working.
I had a similar problem. I'll bet I took off the carb. 5 - 6 times and cleaned it with no success. Very fustrating! One time while checking the fuel level I accidently left off the gas cap, I started it and while running I put the gas cap back on and started to mow and about 10 seconds it died. I thought could'nt be! So I loosened the cap, restarted and it kept running. Any way the small vent hole was plugged. Thats my story!. Good luck.
These little engines require maintenance just like your car does....even more than just a spark plug change. They have issues with parts in the carburetor going bad, carbon build up in the engine and muffler and sometimes even ignition problems. A good bet most of the time is a fuel delivery issue so you have to start with your fuel mix (you said was good) go to the fuel tank (where there is a fuel filter)...the fuel lines (which deteriorate over time and tend to mess up the carb when they do)...etc. Start with the basics and continue on. Rebuild kits are available for the carb and its not too hard...that may be what's needed as the new ethanol laced gas we have is hard on the small carb parts.
