Picked up a new to me Toro 2450 today.
Original Message   Feb 1, 2012 10:53 pm
All the posts about 5 hp SS lately thought I'd add another.  Picked this up at an online auction today.  Toro CCR2450 GTS.  Not in to bad a shape for $23.00
Missing the handle to turn the chute, but I have one off another parts machine.  Muffler was not even connected (stated that in the auction description) to the block
both screws backed out and they had run it like that awhile.  Ran them back in with a little blue Loctite, good to go.
Before I bolted it back on took a couple of shots of the piston, rings and cyl. walls.  All looked pretty good.








Got good spark.  Compression almost 90 first pull, 95 second pull, 105 third pull.
Wanted to see if it would run before I went any further.  Gave it a shot of stating fluid started on second pull, then died.
Good enough, of came the poly carb.  Little water in bowl but no other dirt (kind of hard to tell with all the carb parts being black)
Carb. back together and on engine.  Decided to drain the tank to check for water.  Well... I found some.
Flushed out the tank.  Fresh gas, started on the first pull.  I think I have another keeper and my CCR 2000 is going on CL.
Had to do a little work on the steel pan that the cutting edge bolts to.  Looked like someone had been banging the
blower into the edge of a manhole cover the way it was bent back in the center.  Also need to weld one of the handle
bracket back on.  Those are a weak spot the pan steel and bracket aren't very heavy steel.
May try and devise some type of chute rotator and deflector handle.  Or a combination of both.
Alll the snow has melted here and none in the forecast for the next 5 days.
Just temps in the upper 30s to mid 40s.  This is supposed to be winter time.

Finished up the Toro yesterday and decided to add a couple of handles to the chute today. 
Nothing fancy, but much easier to reach.

Nicely done.  You going to bend the governor tab or just run it at stock rpms?

You'd be surprised by how much more performance you can get even by jacking the rpm up to 4500.  I actually had to slow my 221 down to 4000/4100  rpm because it was pulling me down the driveway too fast.  If you've got a level driveway, the added rpm will extend the throwing distance substantially and the increase in engine speed isn't enough to cause any concern.  The R-tek is a pretty durable engine.  With the split connecting rod, I wouldn't trust it to be spun too high for too long but I wouldn't be afraid to run it up to 5000 rpm on occasion.   

If you get some snow, let us know how you like it.

Nice work, jrtrebor! I like the handles. Was it an eBay auction, with a local seller?

borat, what's split about the R-Tek's connecting rod vs, say, the HSK850's? In the HSK600, at least, the connecting rod is solid at the piston end, and bolts around the crankshaft at the other end. Though I just looked at the HSK850 exploded view (in "Predator Maco shark waiting for boratification.") and I see the 850's conrod is slipped over the crankshaft (as well as the wrist pin in the piston), and does not bolt together at either end. I'm guessing that's what you mean. Which means the smaller 600 is also of the split conrod design, I suppose. Hmmm. I wonder if the 600 will be less tolerant of revs. At least its piston is lighter.

High performance two cycle engines generally have solid conrods  and built up (pressed together)  cranks.  Built up cranks can take a fair amount of power but are not as strong as a solid piece.  Accordingly, when someone wants to ensure their super-modified or racing two cycle engines remain reliable under extreme loads, they weld the pieces of the crank together. 
 
Tecumseh has cleverly designed the HSK 8xx engines to have both solid conrod and crank.  That's a plus.  The fewer opportunities for rotating, reciprocating and other moving parts to loosen up, the more reliable/solid the engine will be. 

I wouldn't be too concerned about the HSK600 engine not being able to take a few hundred more rpm provided it was properly assembled.  Don't forget that just about every four cycle engine has split big end conrods and those engines can take some serious revs.  The only caveat is that if the engine's connecting rod and crank were not properly assembled (correct torque and lock washers), things could come apart in a hurry.  The bolts/nuts that hold the two pieces of the connecting rod together usually have a large flat washer that is to be bent up beside the nut or bolt to keep it the bolt from backing out.  If this critical step is overlooked, bad things can and will eventually happen. 

Chances are your engine hasn't been apart.  Accordingly, if it hasn't let go yet, chances are it won't.
