Good eve. all.  I am a new member. I just purchased an old, don't know how old, Jacobsen Sno-Burst.  I'm hoping that someone will know about this snow thrower.  I'm not sure about the model except it says Electronic ignition and the label on the top-front says Jac-339498 and takes a 50-1mixture.   It has a starting problem but gets spark at the plug.  Any suggestions and information about the age and where to find a manual  would be of  great help.  Thanks kevandhel

* its at least 20 yrs old and probably 30

* once iin a while the manuals go on sale on ebay

*there is a tecumseh manual available (free)on the web for free that has 3-? hp engines( if u can not find it i will look for a link)

* parts are hard to come by.  i got a scraper bar from one of the websites. maybe jerrryssmallengine


*its great for up to 6 inches after that GOOD LUCK. 


*you might want to try a new sparkplug/ clean out the carb or just some new gas.

To you googlers, I've got a photo-tutorial for overhauling the Jacobsen Sno-burst carburetor...

Jacobson made their own engines. Tecumseh engine manual wont help.

Cylinx,
Excellent Link.

Butt, never knew that they made their own engines/
Thanx and thanx

Thanks for the kudos. I didn't know that they did their own engines either. One thing I did glean from the Tecumseh manual was the workings of the idle/load circuits. I've got 90% of an photo-tutorial on rip start repair done as well. I don't suppose anyone knows where I can get the pawls for the rip clutch, or even what they look like such that I could fabricate my own? Mine went *poing* one rip and were never seen / heard from again. I'm currently starting it by wrapping a piece of cord around the output shaft by hand. That's why the carb job giving me a one-rip start was so important =)

Sometimes parts  show up on Ebay.

Thanks to a kind passer-by, I now have a PDF of the original manual including exploded parts diagrams available along with my carb walkthrough:

Jacobsen Sno-Burst Owner's Manual

Hey Guys, This engine is not made by Jacobsen... It is one of the Early Tecumseh 2 strokes.

Friiy, do you have any references to back that up?  The owner's manual (linked above) states very clearly that the engine is a "Jacobsen J-501 ST (2 cycle)".  A quick Google search doesn't give me any reason to think that the J-501 was actually made by Tecumseh.
