engine questions

[Rotore]

since i have to be the wierdo and be into modding verticle engines ya kno.

i might go to the junk yard sept 3 my bday and get a 18hp verticle w/ electric to tinker with.

my plans are modding lubrication (oil pump, oil lines ect.), upgrading thew ignition (battery ignition if possible), port exhaust and intake, valve idk?

ok so on to the questions:

*would a battery ignition work on a small engine like this?

*if so would i be able to eleminate the flywheel? (probably not but work asking)

Battery ignition as in points? It would probably be very hard to do, but is technically possible, although i see no benefits.

As for running with no flywheel, Im not sure, it would probably be very hard to keep it running at idle, but i have doubts as to weather it would run at all. But hey, cant know until you try.

Will not run without a flywheel. Won't even get it to spin over...never mind start.

yea i found some diagrams of it by kolher and read up on it a bit seems t0 have some benefits.

nevermind about the flywheel ill need it to start the engine anyway

And what were those advantages? it would be fairly hard to do, you would have to file out a flat spot in the crankshaft (flywheel side) to actuate the points, make mounts for the points (not sure how you would do that without a welder).

from what i read it said it would produce a "bigger spark, superior to the traditional magneto".

i dont own a welder your right about that BUT my in-law does, i can get him to loan it to me for a weekend. but this is a long-term engine build for me. need to research the battery ignition a bit more before i try it.

ON the lighter side i've been kind of busy and haven't had time to go pick out and engine so right now i'm just debating whether to get a single or twin cylinder. Even thought i'm leaning torwards the twin i think i might have some trouble modding the lubrication system on it especially if its a pressurized. Also a single cylinder would have more torque amd the lub system would be easier to mod so i dont know which to choose.

so c'mon guys give me some opinions should i go Twin or Single cylinder?

2 vs 1

If its a pressure lubed u need to make a new oil pan and then run a pick up for the intake for the luberication thingy.

you lost me there dude.

Basically setting up a lubrication system for a full pressure lube engine would be hard than a splash lube system. If it were me i would take the twin...bigger=better

But if i were going to a junkyard i would probably just look for a motorcycle or atv or something like that.
