Tecumseh outboard carburetor rebuild primer
Well it come's as no surprise to me that so many have had troubles rebuilding the Eska based Tecumseh carburetors due to there deceptively simple design, so simple that at first glance you think this is a “no brainier”. Well its not that easy is it or you wouldn't be reading this primer?
So lets start with dis-assembly, the first thing here is to make a note, mental of other wise of the orientation of all the parts, you will of course forget what you saw or if your the more unlucky type someone else has been there before you and your carb is out of whack and it makes no difference what you see, so tear into it and don't lose anything.
Now that we have it scattered on the kitchen table we need to order a kit, they are widely available from from a number of sources but I won't go in to promotions today.
Regular 87 octane 10% ethanol gas is the best soak/cleaner for the buck, I generally soak a carb over night to loosen the varnish and make cleanup a breeze with even with the worst cases.
I use a combination of small brushes, fishing line and and ignition wire that I have untwisted to clean the jets....Yes there behind the welch plug and you should have removed that when you disassembled and soaked your carb, give this area special attention and be careful, may “running engine issues” emanate from tiny bits of crude in the jets.
Now that the pump gas and scrub brush has eaten the paint and varnish from your carb and it looks like brand new its time for the carburetor spray cleaner and compressed air, all that I can say is “every orifice” over and over until your a believer.
OK, now we have a clean carburetor and kit with welch plug, a float that will not sink....Oh I forgot you need to check that before you buy your kit or pay extra for shipping another part, just hold the float under water and look for bubbles and check for internal sloshing when you do your tear down.
Now back to the primer, This is the most important and finial part of this primer, you must have instructions! or a Tecumseh engine manual that covers the outboard carburetor, this is the key to your success and there is no other answer or explanation, you will need this to reassemble and you will need to follow it like it was your holy book, it will not lie to you like me, the correct Tecumseh engine manual is open honest and straight forward and easy to follow.
Be sure to either buy or make the tools that the manual says to use, everything you need to rebuild a Tecumseh carb can usually be found in your own tool box or modified from an existing tool, also double and triple check your work.
I personally depend on my plastic calipers whenever I go out to my shop or to the parts store...there like a security blanket to me and I never leave home with out them, you shouldn't either
Consider yourself primed to rebuild your Eska based carburetor, everything you need to know is contained here in.
Good luck and happy boating,
