Bought a new out of the box, carb for my 10/28 1992 L Head Tecumseh blower. Is there any adjustments I should make? I really like working on the blower should i invest in a tach? I plan to use that motor in another blower, and eventually put a OHV engine in this one. Like tweaking adjusting and making the unit run better. Any advice appreciated.

I put an adjustable carb on my Ariens last year (Richie got me going on this one) and am glad I did. I purchase a tach/hour meter . I think it was about $20. From using the tach, I dialed up the rpms to exactly 3600 rpm. Other than making slight adjustments to the mixture, that is about all that can be done. :D

bbwb-

Did you notice an improvement with the new carb? What size machine is it.

Thanks, rob

Rob, the engine is a 10 hp Tecumseh L head, with a 28" cut. It's old, 1992, but using during the last storm, blowing heavy snow, it hung in there like a trooper. I got a new respect for the L head engines. I see why they put them on the new machines, a work horse. After putting on the new carb, started first pull with old plug, (to be replaced tomorrow). Picking away at this machine to make it better. Bought it used as a project blower as working on it is fun. The new carb seemed to get me a couple of RPM on top end, but that could be a placebo effect since I do not have a tach or put it under pressure. I like the idea of a new carb. Rebuilt a carb for my lawnmower and goofed it up so didn't want to go the rebuild route. The carb was initially for another blower I own a 1887 10 hp Tecumseh 32" cut Craftsman but I decided to put it on the newer 1992 unit.

Yes, I did see some improvement in the throwing ability. It did smooth out the high speed operation. I have a 10 hp Ariens 1028 Deluxe, 4 years old this February, Tech L head. My neighbor also has an Ariens 10 hp, about 4 years older than mine, I can out throw him :D

When I reached EOD with my blower, my next door neighbor was also at the same point. We watched each other's blowers working and it was a draw. I was hoping my used 92 would out blow his new unit, but no joy. Ordering an impeller kit tonight to increase performance. Got a bug in my bonnet about the performance of my used machine. After using the slide rule, research and devolopment, parts, pulley's hp increase, trial and error, internet research with the best minds in the business helping me, my guess, is after all is said and done, my 92 will end up costing more in the end than his new unit, but will have a gem of a performer and something to talk about, along with the satisfaction of making something that is old better than it when it was new. I am glad I am not in the car racing business, because that 65 Mustang would cost a lot more than a 05 Mustang after I got through with it. But the 65 would woop the 2005.

Garandman, I got to get one of those! Did some more work to the blower today. Tightened the "drive" cable, as the tracks would not work when going up a steep hill. I think the friction wheel was slipping a bit but now it moves along nicely. Did a little test blowing with the remaining snow in the yard and I noticed two things. It starts without having the choke on full when cold. With the choke 1/2 way it starts cold. I opened hur up and threw a bit of snow at full throttle and it seems I have (perhaps placebo effect), a little more power and a bit smoother all around. The real test is 40 minutes of hard blowing and hopefully it doesn't do the stall thing after it gets worked hard. The carb seems to be factory adjusted ok thus I may not tinker with it as I may goof it up. It will idle real slow, almost Harley like. It's snowing hard at the moment, so got to phone my plow guy and tell him not to come as I got the blower now. He's been plowing my driveway for 10 years now and I hate to make the call, but the snowblower has taken over. What I like about the blower best of all, no big gobs of snow that the plow leaves. But then again he was fast and reliable. I am going for a gas run before the roads get too greasy.

well Garandman...
that vanguard would certainly make your ariens a formidable machine (not saying its not now cause im sure it works better now than new).
vanguards area little pricy here .
i shortblocked 1 last summer it was a 16 horse unit and the shortblock was about 1900 i beleive...kinda scary.
the other part is ,i almost have enough parts to build one.
hmm that would work pretty good on my st1032.
