SOURCE: Backfire Tecumseh Generator

To maybe convert your Flamethrower back to a generator, Make sure the fuel line is a good quality thick rubber material (like OEM )since it passes through the engine,HEAT is a issue, if it has been modified to steel, or it's thin rubber, it will overheat the fuel on its way to the carb and cause backfires after the engine warms up , ( vaporizing gas and pressure bypassing the jets flooding the engine) I use 1/4 inch Goodyear sold at Autozone , one of very few name brand quality parts you can get there. The other possible cause is carbon deposits built up on the leading edge of the valve not allowing the valve to close all the way, just clean the valve, it is caused by too lean or rich carb setting or clogged jets, if it is a newer style carb with a pink main jet then debris in this area will always cause backfire, check and make sure the old tiny O-ring on this jet is not still in the bottom of the shaft, people forget to pull them out all the time or give up trying to pull them out, I use a paper clip and bend the end 1/8 of a inch @ 90 degrees to fish hook it out of there, CLEAN THE SHAFT with carb cleaner and a Q-tip.... A Tecumseh engine will always backfire if the carb or airflow is not perfect and sealed tight !!!!!! it looks simple to rebuild the carb but you must take your time and look close, clean it very well, make sure the jet is SEATED properly and all tiny holes are clean, use guitar string not torch head cleaners as they will enlarge the holes and make your carb run rich.

SOURCE: I have an old pressure washer that uses Tecumseh

When you get it started, move the choke to the middle, then let it warm up. you might have to move the choke back and forth until it warms up, keep the throttle wide open.

SOURCE: not getting spark

I would check that I didn't have a key sheared off in the flywheel, that the start/stop switch isn't faulty, and that there is no missing or weak flywheel magnet. Hope this helped and best wishes.

No spark in my toro 38080 mod# snowblower,new plus,new gas ,fuel line,primer bulb,line, no spark


The Toro 38080 was made from 1979 - 1993.

With it not producing a spark then you have an ignition system problem. Depending which Tecumseh HM80 engine setup you have you may have either an internal ignition system or external. By this I mean under the flywheel or external to the flywheel. There was also hybrid system that was both internal and external.

This engine could either points based system or a CDI all in one coil pack.

Now if it is an internal points systems it will be major an under taking for someone that never worked on one these engines as if you replace the points the ignition system must be re-timed. Note that where a few fix time setups. You might get lucky and it just dirty contacts which can cleaned without up setting the timing. To gain access to these points the flywheel must be removed.

Probably the best to do first is to download a copy of the service manual to see if this something that you can do or if you what to get a small engine mechanic that is experienced with Tecumseh repair to do.

Ignition system info starts on PDF page 67 (manual page 63) in the following manual. It will explain on how to test and repair the systems involved.

8HP Tecumseh with no spark


Check the gap between the coil and the flywheel. You can fold a dollar bill over a few times (3 or 4 layers thick) , place it against the flywheel , **** the coil up to it , and then tighten down the coil. This will give you a good clearance between the coil and flywheel and promote good spark.

Essentially I am suggesting you use the folded dollar bill to set the coil to flywheel distance/gap.

If it still doesn't work, I am at a loss. Is this a multi cylinder engine ? If so , does it have points or electronic ignition ?

No spark on tecumseh 4 hp lawnmower engine


Hi,

There is a shutdown wire, this wire is grounded somewhere along the route. Look at the coil for this wire; it shorts the coil to ground so no spark can get out to the plug.
Let us know if you want to know something else accept the suggestion.
Thanks for contacting fixya.com
