Back in the 1970's/80's before Honda offered the GX-series overhead valve engines they made the G-series flathheads in serveral sizes. They offered the G35, G42/50, G65/80, G100, G150, G200, G300 and the largest was the G400 like mine pictured below:
Its a 406cc./24.8 cid. - 10hp model with 16.6 ft. lbs of torque. They weighed 72lbs and were avalible with or w/o electric start.
Here's my G400 sitting next to a GX390:
________________________________
My other oddball engine is a Tecumseh Star. This engine was highly modified version of their H100/10hp industrial model and intended to be used for kart racing. They were sold in an un-assembled kit form complete with a 3-stage header and a Tillotson HL363 Methanol carb. Its specs were 357cc./21.82cid. with a 3.312" bore and 2.532 stroke. These engines produced around 20hp (had no govenor/reved to 7000rpm) with the stock parts but had the potental of reaching somewhere near 40hp when further modified and up to 50hp when ran on a Methanol/Nitro mix.
These engines bolt right up to a standard Briggs-5hp/Honda GX200/6.5-clone motor mount but are wider and come with a larger 1" pto sizing. They made/sold about 1000 of these before the componey bit the dust a few years ago.

Unfinished projects king.
You have to let them warm up and warm down for 10 mins or so.
Man do I have some engines to add to this thread, will tomorrow when I get some pics

All engines are supposed to be warmed up or run easy till they get hot. As for cooling down, that's usually a turbo related thing, buy a turbo timer and you are good to go.

its definitely an xj by the valve cover and the carbs
if its shaft driven then i would say it is a 650
you have an xj mike?

Kinda odd, but becoming a little mainstream on here. Vertical shaft lawnmower engines turned horizontal. My twin Lawn Boy Duraforce engines currently going together for a Rupp Dart I'm building.

Doin It!!
anyone know much about the hydrogen engines. i have seen a few vids of 2hp engines running on it, but its apparently very temperamental. I think that bmw have brought out a car with a hydrogen engine? anyone know much about them
All i know is if you crash it you go boom.

Pro- one idea to the next
ok so I have been doing alot of research on the wankel/rotary engines lately, so I will shed some light upon the subject.
The rotary was mostly known for it being used in the rx7's
http://en.wikipedia.org/wiki/Mazda_RX-7
they work alot like 2 stroke motors meaning they require 2 stroke oil.
they have 2 different sets of spark plugs, a leading and a trailing.
Their source of power is their ability to rev at very high rpms, so it doesnt fell like there is any torque untill you start getting close to a regular redline.
They are cool.
instead of pistons they use rotores (see the video)
hmm...they get bad gas mileage, its a performance motor.

actually most of them do. its a matter if they have an oil pump or not. the oil pump is electric and usually fails alot, so they cut corners by just premixing.
