hm100

Here are some before and after pics of my big block :scooter:

Ok have a super bronc with HM100 it came originally with carb mounted directly to the block right beside the exhaust and when we used to ride it in summer seem like it didn't run as well when hot ,like maybe starting to vapor lock. So the newer ones (mine is a 1981 model) have a diff intake...

I need a ring gear flywheel for my VT-10 Super Bronc HM100 engine. It must work for the light/charging coil also. I'll buy or trade my old fly wheel(lighted/no ring gear) John

I now know my super bronc 10hp runs :thumbsup: It is pull start only. I would like to make it electric start also(12v DC). My engine has some sort of lighting coil but no ring gear for the starter. Does anyone know the part # i would need to do this ? Can you just add the ring gear to my...

I think I need a new carb for my bronc. Took the carb apart & the bowl area is all rotted out. The needle is also pitted very badly. Anyone have a carb for this engine. It looks to be a 1979 by the date code. I'm not sure if this engine will even run so a new $100 CARB IS NOT in the cards...

I bought a Super Bronc as my first mini project. The bike has no lights or electric start but the 3 wire plug for the kill switch/lighting coil is there. What type of alt/lighting coil system does the bronc come with? I have looked in a PDF manual I found & this engine has a number of systems...

Im looking for the following parts for a HM100: 1. Lighted flywheel 2. Starter ring 3. Intake Lets make a deal. After seeing all of the Bronc projects going on, I'm ready to get my big boy rolling. Tim

Pics 1 & 2- New Tec HM100 short block bought off ebay by a fellow OldMiniBikes member...he had them ship it directly to me for machine work on the tapered crankshaft. Pics 3 & 4- He'll be running a 3/4" torque converter driver, so I'll machine the 7/8" tapered crank down to 3/4" OD x 3" long... Pic...

rebuilt the carb and rode it yesterday w/out any trouble after having set for quite a while apparently and then today it is flooding out and leaking gas from the air filter side of the carb... i mean really coming out of there too. i noticed (since i always install clear fuel line) that some...

i know i've asked this before.. but i guess what i really need is some pictures of how to remove the crankshaft.. i'm afraid i'm going to do something wrong and mess up my engine. any help would be greatly appreciated. thanks

I'm looking for a crankshaft to replaced a tapered one on a 10hp HM100 engine off a generator.

Anybody ever get a hm100 tecumseh squeezed into 1970 rupp frame? I have a opportunity to buy a nice clean hm100( 10 horse temcumseh) I would like to put it on a beat up 70 rupp that I have, But it looks tight! I have seen 5 horse bigblocks in there, but never a 10 horse. Is the 10 horse much...

need a 8-10 hp tecumseh for my bronc,or a repair guy in los angeles area

Looking for an education and/or informative links on the Tecumseh HM100 engine. I take it that this engine is not the same as the "Star" engine, or is it? If it is not... What is the difference? I just brought home an electric start HM100. The identification # is: 159290M (B) D.O.M...

Picked up a tecumseh HM100 the other day. has cast iron sleeve, starter, and lighting coil. another low hour big block power house. getting ready to clean it up. I think I will be painting it black.

can anyone recommend the ft lbs. of torque for the flywheel bolt on a tecumseh hm100? thanks for the help...:thumbsup:

tecumseh hm100 throttle linkage wanted. i have an older white hm100 in need of a complete throttle linkage. originally had the 3 bolt, zig zag shaped upper bracket etc. pm me, and let me know what you have. thank you. :thumbsup:

would there be any benefit to putting one on a Tecumseh powersport? Is that carb any bigger or much different than the stock powersport carb? Thanks.
