Unknown Techumsa Engine.

[wobbedennis]

I have this old style, brown Techumsa engine that I need to find the numbers on, so I can get a set of floats for. It has the old Indian logo on it, and it says to use 30W in the summer and 5W-30 in the winter. That's all I have that and the address to the plant it was made at.

What you describe could fit a lot machines.

What is it on? Do you know the HP? and can you post any pictures? All this plus anything else you can add might help us pull the needle out of the haystack for you.

Look for a small metal tag , or signs of one having been there, bolted to, sometimes the breather cover.. sometimes one of the crankcase cover bolts (and tag folded up over crankcase) - The same sort of tag can be found on many Short Blocks (SBV or SBH models)

If you need float for carburetor, possible to find the carb MFG number (if Tecumseh) or model (if Walbro) and cross reference it to tecumseh part number, which can then be used to do a "where used" lookup and have at least a range of possible models..

Or you can measure bore and stroke, find the displacement and look at engine spec charts to find the HP it might be, from which you can sometimes determine your base model... and then take crank measurements, with old fashioned crank drawings data, may be able to identify further the exact model and/or range of spec numbers..

Other locations for model number tags: if vertical, riveted to front of engine block (you may find signs of rivets or bits of tin that show tag was there but ripped away) (more likely on ECV, TNT, VHxx, LAV model series) , the aforementioned tag, it can sometimes be stamped in the cooling shroud instead of engine cover..

I have also seen model numbers stamped in the control bracket, air box (on snow king engines) and I've even seen some where they stamped or engraved model-spec in the engine block itself (but that would not have been OE Factory done, usually)

Other than that, all you can really do is take an educated guess.. maybe post some pictures and we can get you within a model range that it may be for. if there's 120V electric starter (Snow King) , remove the switch box and look under it for numbers.. if engine has been painted, that, too, can cover or obscure numbers (Removing the blower housing and look for indentations from the inner side of the housing can often show you where to scrape away paint.rust and take a closer look)

it's off of a wood splitter, but I don't think it's the original to the splitter. It's a modern design. It's bolt pattern is odd too. It bolts into the block, no nuts required to secure the engine, kind of. It's got a mounting bracket that is bolted to the bottom of the block, and bends down, to where it then bolts to the machine. it does that on both sides. It's a gravity fed system, and the fuel line runs behind the fly wheel. It's a L-head engine, and I looked for a tag or a stamp of any kind, I cannot find one any where. There are just the stickers that are on the engine's shroud.

2 clues now.. your first post mentions it says use 5W30 winter, which would mean it is probably at least 1980's vintage,I suspect , not that old and second from your mounting description, it's horizontal shaft,. so we know your model number most likely is gonna start with H

get some pictures, or some sort of number off the carb perhaps, and maybe we can get a little closer, otherwise, it is just a guess.

Your mounting is not unusual - indeed. most Tecumseh I have seen have that capability - threads in the block so you can mount like that.. and some actually have that plate bolted to them from the factory, which is what makes them a horizontal shaft (Block could be converted to a vertical, if I remember right) .. could still be anywhere from mid 70's to late 90's model Horizontal shaft

Not but ONE float....632019. I've been out of
the loop for some time now, and this brass float
may be replaced by a plastic version? Brass versions
were abundant in the aftermarket (Rotary, Oregon, Stens)
631021B needle & seat and bowl O-ring. You'll need that,
too.

Confirmed. Number 632019A - also has a dampener spring included in kit, as spacing between hinge is smaller... and of course the disclaimer instructions "only use where originally equipped"...

Still are

Yup, and if you buy OEM, kit also includes bowl gaskets too (27110,631028A) while aftermarket kits (most Ive seen) don't.
