h40

First time posting on this forum. I am a volunteer for a 501c3 non-profit. A group of folks are working on a Ken Bar Whirlwind with an original H40 engine. The aluminum cylinder walls are scored beyond repair from possible cracked ring(s). The crankcase/valve guide breather is expelling...

Looking for a nice runner with a 3/4" shaft. I have some things for trade with cash if interested.All cash price ok with me too.....PLEASE RESPOND WITH AN EMAIL OR A NOTIFICATION...THANKS

Got ahold of a Whirlwind with the Tecumseh H40. A couple questions: 1. It has an oil leak from the gov shaft. Yes, the shaft has some play, but I'm thinking maybe the breather isn't working right and the pressure is blowing oil out the governor shaft hole. All suggested...

Just about to repaint my 66 h40 and I was wondering which decals, flag or ballon? Which is correct for that year engine. Thanks

Looking to freshen up my what I think is a 66 h40, is there a rebuild kit out there or do you just need to find all the gaskets and such separate? Thanks

I've been looking around so I stopped by an old lawn mower shop in my area and they had this sitting on a shelf in the back $40. The petcock was closed with old gas in the tank, drained, cleaned the tank and threw some fresh gas in her and she fired right up and sat there idling:) can anyone...

this engine came on my arco not original. off an ariens snow blower, would like anyone to decode it.im going to tear it apart bore it .10 over with new piston and rings and gaskets valve job. maybe mill the head. and blast it and repaint it.

Is it a 1963 someone told me 8 1 63 Not sure. It's similar to Ariens Snowblower of the early 60's Thank you

Not sure if I remember this correctly and can't seem to find the thread. I need to adjust the governor. Do you push the throttle all the way open (with spring and shaft installed), loosen the governor screw on the block, push all the way open and retighten the governor screw on the block.:out...

Anyone modded a H40 tecumseh. Got one on a ken bar whirlwind bike i just picked up and don't whether to try to mod this engine or replace it with clone engine. The H40 runs good and looks to have low hours on but don't know alot about tecumseh engines or where to get parts for it.

Hello everyone, I just found this forum and have searching around a bit to try and ID my engine, but so far have only confused myself more lol. The tag on the shroud says its an H40 55805a and the DOM is 7352. But from what im reading is that an H40 is really old and there are only HS40's...

While removing one of the head bolts from my H40, the top of the bolt snapped leaving only a small amount of the bolt sticking out. I've begun to drill it out and the thread seems to be rusted to the rest of the bolt as i cant find the thread of the hole. Any suggestions?

On the block is a Sears model Super Two-Speed. However, it's missing the jack shaft set up for the two speed portion and is using a chain directly from the motor to the drive sprocket. Other than that, it's in great shape! I believe the paint to be original, although with some scratches. The...

Does anyone know the bore and stroke of thses engines so I can ID this one?
