favor to ask: ST 16

1966 Views 16 Replies 9 Participants Last post by  GT_80
Hey guys,

I want to find out if my st16 has spark, missing the starter, don't know enough to feel 100 percent comfortable just checking the coil. Anyone got a starter and chain i can borrow? Still looking to sell the 16, just want to know the condition, and Dont want to waste money on a starter just to find out there is no spark. Thanks!

Well if your cheap like me, All I do to check spark if there's no starter. Is take a peice of rope and wind it counter clockwise around the pulley. Set the plug on a clean metal surface and give it a pull. If it has spark, All I do is put a big socket on the flywheel nut with a 3'' extension, And an electric drill. Then just spray a little ether in the intake, And crank it over with the drill and as soon as the engine catches pull the drill out. If the engine doesn't sound like a wood pecker is in it, It's probably a good motor. Just give the carb a good cleaning, And run the motor for a while on gasoline. And if it runs good with no noises, knocks, or smoke, Then you can get a starter for it. Those OH160 Tecumsehs are pretty forgiving, They're very reliable and well built. So if you decide to keep it, They're one **** of a work horse. Hope this helped, - Brad

Big help. Couldn't figure out how to pull start with sprocket type flywheel, i saw how to do it with the pulley type. I'll try the drill method

Make sure you don't use an impact driver- that can overtighten the nut on the flywheel, and damage or break it off (in the worst case)
You will need a BIG beefy OLD drill with at least a 1/2" capacity to whip that 16 HP engine over --one like an old Rockwell with metal case and pipe handles..smaller drills might be able to spin it with the plug out,but not have the torque to START it!...

I made a hand held starter out of an old Ford starter I had from an old T-bird,the kind that had the starter drive facing backwards towards the flywheel--I removed the starter drive,that gives you about 4" of shaft thats 9/16" or so in diameter,that you cam put a v-pulley on--or grind the end of the shaft square so a 1/2" socket fits on it,then you can use it on the flywheel nut..I put a "riser clamp" around the case of the starter for "handles" and wred a Ford solenoid to it so all I had to do to use it was clamp a pair of jumper cables on it to a battery,and push a button to activate the solenoid..made starting engines with rope only start or cranks a heck of a lot easier!..

I still think you can pull your new 18 up in front with them offset to line up drive pulleys with a long belt in between them. Have someone push the 16 back a little just enough to tighten which will turn motor over while you check the spark plug. There was a pic around here somewhere how someone did it with a tractor and gravely 2 wheel

ugh yeah i totally forgot it spins on both sides, forgot about the pto pulley. *feeling dumb* thanks for the suggestion!

I have one of those drills! I think it's an old Black and Decker- I used it to drill a 4 1/2" hole in my wall for a new dryer vent, and it is one of the old school ones that have the button on the handle to lock them in the On position- It grabbed the wall when I was drilling and about broke my arm off!!! :bonk: I think that one would whip a motor over :D

I must have the same old drill GT 80 :) My father had it and gave it to me, fairly old.....lol
I was drilling the holes through my well casing with a hole saw [pitless adapter install] it grabbed and took both feet off the ground. i felt that for days.
Mine looks like this

If he's spinning it over with the plug out, even a wimpy cordless drill should do OK.

My dad had one of those old manly drills, his was a Craftsman with exposed tie bolts to hold the motor together. It had at least one broken wrist attributed to it, and the cord was patched multiple times since it seemed like it would keep running for a minute after you let off the trigger or it was ripped from your grasp... I managed to stall it once, but the force of holding onto the handle so hard locked my trigger finger on and I had a heck of a time loosening up enough to let off on the switch while still holding onto the drill so it wouldn't get me. I may have pooed a little bit by the time it was all over. ;)

LOL. They dont makem like that no more.

GT-80,that drill looks a lot like the one I used in trade school shop class--teacher wanted to make a big hole in a heavy metal work bench top,so we could bolt vertical shaft engines to it to test run them...why he had me drill about 50 1/2" holes in a circle close together and use a sabre saw to finish cutting the disc out ,instead of the cutting torches,I cant say..

Anyway,I was standing on the bench,drilling the holes--the drill had 1/2" pipe handles about 2 feet long on it,and I decided to use the trigger lock so I could use both handles instead of one and have to hold the trigger "on"...bad move!...the drill bit snagged as it broke thru on about the 20th hole,and the torque tossed me right off the bench,onto the floor 3 feet down,before I could release the trigger..the drill kept right on spinning like a helicoptor,winding up 50 feet of extention cord around it in about 4 seconds,and it yanked the plug right off the cord,and pulled the outlet box and conduit right off the wall, before it finally stopped!...

Maybe that why they "dont make 'em like that any more"--they were man killers!..

I have used an electric motor I found at the dump that had a 50:1 gear reduction box on it as a "electric starter" too,it was only 1/3 HP,but it would spin even big 2 cylinder engines over like nothing,using a v-belt pulley--a bit too slowly sometimes though...I had to put a bigger pulley on it to get the cranking speed up to normal...I mounted it on an old hand truck,all I had to do was put the belt to the engine pulley and lean back on the handle bars to tighten it,then push a button to crank it...wish I still had it,I sold it to a friend,who has since passed away,and I think it was probably scrapped..:(

Before I knew better I did that on a lawnmower motor. What a dummy. Split the flywheel. Bad idea. Still trying to forget about it.
I split a few in half too ,using an air impact--also had a few Tecumseh's snap the end of the crank right off flush with the flywheel--it stayed in the nut !..:eek:..one was a customers mower I was "tuning up"...had some "splainin" to do when he came to pick it up!..

I use only hand tools on flywheel nuts now...
