Hey guys give me your thoughts on this build should I go Tecumseh or Predator ? Rebuilt Tecumseh HS40 mostly stock and will stay that way. Or a Predator 212 Hemi head (60363) that will stay governed but maybe some after market parts. OH and I'm a big boy..:anon.sml:.so give me your honest...

Ahh the beloved HS40, for the last few years I have wanted a first year HS40, only because I was curious about it. Recently I found one on ebay for a shipped price that was reasonable enough to take a risk on. Its actually an Ariens snowblower setup that will need some converting, but in...

Another novice question for those with on-engine vertical seam tanks. Engine originally had horizontal-seam, plastic tank with outlet nipple in the center/bottom of tank. No problem with fuel line radius out of the tank into the shroud. I now have reinforced rubber fuel line installed and...

Hello there! Working on a cool hs40 from a mtd I have. My questions are about the bore and what is considered bad/good. And what specifically I should do with what I have. The bore looks OK, and to touch except maybe one I can get a fingernail in. Should I just re-ring and try honing it. Never...

1970 HS40 As the title says a challenge, given to me by a good friend. HS40 not mini bike correct or lighted. Hopefully its a good engine and with a little luck I can make it work on a mini bike.

I have 3 HS40 engines and 4 Tecumseh carbs. I've taken the carbs apart, soaked them in carb cleaner overnight to no avail. I put in a new carb kit which is just gaskets, o rings and a needle... One carb works better than then the other 3. It will idle and runs well at Wot but sometimes has a...

I am wanting to know the importance of removing and replacing the welch plugs on the 631588 diaphragm carburetor during a rebuild. The engine went through a flood and I did a complete tear down of the entire engine to clean, dry old and fresh lube approximately 1 week after the flood to salvage...

The slant intake from black widow motorsports states that it is for both HS40 and HS50 engines. Is this possible? I am wanting to know if anyone has tried the slant intake listed on an HS40 engine size using a floated carburetor that used to run an unslanted diaphragm carb setup.

I read where Rupp's used a 3" crank on their HS40 engines for use with a torque converter. Ok. Now... Can someone tell he where they measure the crank from? I have a standard length crank and want to make a spacer but I need an accurate way of measuring what I have vs where Rupp measured it...

I'm working on a Rupp Scrambler with the slanted engine. I have a HS40 I want to put on it but it doesn't have a slanted intake. I'm sure I'm not the first one to do it. What are your experiences using a non slanted intake on a slanted engine? I'm searching for a slanted intake but haven't...
