okay so I have reassembled my 10HP TECUMSEH that now has a 3" long 3/4" bored Output on it. Clutch fits perfectly. BUT..... This 10hp motor is MUCH wider then the stock 6hp Tecumseh and the output shaft hits the tire and the side cover hits the brake band. So i think i need to make a new motor mount a weld it on about 3" to the right. Should I do this? and what size metal plate would i need, and how would i add the 4 SLOTTED holes? angel grinder? Thanks, pics if needed!

Maybe build a plate that bolts to the stock plate(stocker is already slotted).
Well it looks like the motor will match up perfectly if i slide it over about 1/2" to 1" and i have a mounting plate on a old wood chipped frame that i am cutting off right now. i have a buddy who might be able to weld it today, but i am very busy so IDK.

just use 4 angle iron and space it the width of the mounting bolts and weld. no drilling slots
And will hi temp silicone be fine on my exhaust? I plan on running about 20" of tube from the engine down to the a larger generator low tone muffler and i think i am gonna use a 1" pipe, high temp silicone, and a hose clamp to adapt it. The silicone goes to about 800 degrease F

You and your sillycone...most exhausts will get above 800 degrees. I suggest just buying the right **** gasket, or i guess you could cut one out of copper sheet.

If it doesnt use a gasket, why use sillycone? I would never weld a muffler on...

For someone who acts like they know about engines, you really need to re-consider ever taking the step of welding a muffler this is sometimes the first step to a burnt valve.
And yes, you will need to move something... should've noticed that the block was different man.

Burnt valve from welding an exhaust onto a block? doubt it.
You could run one of these without a muffler at all for quite some time before you have a problem.

Heh, I'll upload a picture from the customer who came in on Wednesday if he decides to bring that Tecumseh in this week. I'm freaking amazed it was able to do the damage it did. He had to buy a new head.
I'm seriously not much of an engine man here, I can do a few things, mainly I just work on the karts, but it does make sense to me if they do a poor job welding, have too short of a straight pipe exhaust, etc.
Now you've got me curious... I've run straight pipe mufflers several times on these engines, are you sure you wouldn't damage something running no muffler?

It should not do anything horrible as long as you re-jet the engine as needed. May shorten exhaust valve life, and you will most likely lose some bottom end, but thats it.
maybe this pic will explain things better. Im not welding to the block, im going to use threaded pipe fittings from the block down to a muffler (about 20" of pipe) and weld the muffler to the end of the pipe, got it? Sorry to be so misleading, bad habit i guess lol. And i didn't know the dimensions of the motor as it had been apart for quiet some time.

I'm guessing the customer simply wrecked something through the welding process... though I'm very sure using something like that more than a few times could damage an engine seriously.
Are you sure you want to restrict the engine that much Solomon?

so your gonna use silicone pipe to make the bends in your exhaust pipe right?
and the hose clamps to attach it
so you want to know if high temp silicone pipe will be alright to use to make the bends on your exhaust.

Slotted holes aren't that tough. Drill a hole at each end of the "slot". Drill these holes at the diameter you want the width of the slot, ie 1/4" wide slot= 1/4" hole. Using a straightedge, mark a line from one side of a hole to the same side of the other hole, repeat on other side of holes. Your slot is now marked. Using a thin kerf cutoff wheel in a grinder or similar tool, cut the material out from between the drilled holes. Voila! File edges smooth, and away you go. VERY fast and easy with some practice. The cutting wheels I use are 3/64" thick, so they're quite fast and accurate.
