havent been here in a while :)

my cuz gave me a generator he was gonna throw out.

is it worth restoring?
it needs a carb, maybe coil pack, spark plug wires, and AFAIK the flywheel is seperate from the engine, so it takes up PTO space

anyone got an extimated hp output?

[robertdjung]

10 hp? looks heavy! Sometimes it's hard to get to the PTO on those.

[Russ2251]

2 cylinder...could be 16 hp or better. I dont recognize it. From an RV?
There must be an ID plate on it.
Send it to me. I'll get it running. I could use a challenge.

[ed1380]

yep rv generator.

it shouldnt be hard getting it working. just carb and ignition.

so do you guys think it's worth it?

[crazycart]

Who cares what its worth,slap er' in a mini bike!

[Russ2251]

Most generators I have worked on have a tapered shaft making them pretty much useless for anything except... well... a generator.
Based on what I see in pic, I would probably put it on Ebay with a starting price of $150 and see if anybody bites.
It will bring more $$ if it runs (duh).

[ed1380]

cant you get a clutch/torque converter for that diameter and it work?

so any coil pack and any carb will do? as long as it physically fits?
cause we got a equiptment junkyard here (backyward of small engine repair shop) :D

Useless??? :confused:

snowmobiles use tapered shafts,you can find old sled clutches pretty cheap(i got one for my golf cart for 15$)

i would say a tapered shaft is better in some applications than a regular shaft.you can put the power to the ground alot better with a cvt from a sled.

you could make a pretty badda$$ go cart you dont see to many with opposed twins.

[Russ2251]

It depends. As I said in previous post, most generators have a tapered shaft with which a clutch cannot be secured. But you might get lucky and it could have a straight keyed shaft. If it is 1 inch (maximum) or less in diameter, you just may have struck gold. You might be looking at some serious wheelie material given the kind of mass/hp you have acquired.

Good question. Check coil first and make sure it is indeed bad. Coils are notorious for outlasting engines. It probably is identified and still should be available commercially.
Carburetor may be different story. If you have a carb with same bolt pattern and venturi size you can probably use it. If bolt pattern is different you can always fashion an adapter plate to accept it.
Good luck and let us know what the outcome is.

None of my snowmobile clutches will fit any generator that I know of.

The engine I'm using on my kart came from a generator and has a tapered shaft. All I had to do was dremel out a keyway and use a pulley that I got from a local garden store. It fits on perfect. If yours has the same thing, you could do something similar.

[2or3wheels]

looks like a beast. DO IT. Remember on the carb issue, if you dont have one that fits and you have to make an adaptor go with the bigger carb :) .

[ed1380]

thanks guys. you guys are making we want to put more effort into this.
I might check the coil today. what sucks is that the wires from the sensor to the coil are burned. and one wires to a plug

about the carb. i know to match up bolt pattern, but what about A/F ratio? is it close enough on all carbs to work?

[kibble]

A/F ration you will probably need to play with the needles. I really don't think it would be the same ratio if you took the carb off a single cylinder engine and bolted it on a two.

[2or3wheels]

yeah just put it on and go form there, use the settings the old carb had and adjust form there for your motor. Looks like it has electric start too, snazy.

[ed1380]

yeah. electric start. too bad the flywheel is on the PTo and i might have to get rid of it.

as far as i know i have one working coil, one coil wire, and one good spark plug

the generator originally had a fuel pump on it. will i need one when i fix it? or will it suck it up by itself

as with teh carb. I'll go to the junkyard and see what they have

[2or3wheels]

as long and there is fuel getting to the carb by gravity i think your good.

Kibble, I am new here and have a 10hp Subaru motor off a generator with a tappered shaft as well. I was hoping to use a centrifical clutch with a sprocket and was thinking of having the shaft machined to accept it. Before I do I was wondering what kind of set up you were running and if you had pictures available? What is the pulley you are running and its purpose? I really do not know what direction to go with but I want to use this motor as it runs really well and it was FREE!!! Anyone else with suggestions would be greatly appreciated as well! Thanks!

[2or3wheels]

wowo 10hp for free?? I dont know f making a filler to make a cent clutch fit would hold to 10 hp but i think that would be easiest, otherthan finding a snomobile clutch to fit and getting all the belts and chains to line up and finding where to put the pillowblock bearrings.

making a filler? (explain please) I have found a cent. clutch that will work for up to 13hp. Cent. clutch is defenitly the easiest.

[2or3wheels]

you get a filler to make the shaft 1'' or 3/4. like a spacer but tapered inside to make the shaft straight and untaperd on the outside.

[timstar]

Useful information and greatly appreciated. The shaft is quite long though and the tapered part is in the middle which I do not believe will line up correctly to use on a single wheel application. I could move the engine plate over or make a live axle set up but I believe it may just be easier to cut the shaft shorter and put a keyway in it like kibble did (waiting for reply from kibble before I make a final decision). Maybe I should try and take some pictures and begin a new thread for my entire project?

[2or3wheels]

make a thread of your project. Maybe cutting and making new would work.

[Russ2251]

ed1380, have you found any ID tags/labels which identify engine manufacturer and/or power output (KW)? Pics would help. With this info, HP could be approximated.

[kibble]

@ timstar

Hey tim, you were asking about my setup. Here is a link to when I first started my kart. You can see on the last page what I did to the shaft and towards the end you see how I set it up.

I have the pulley on the engine going to a pulley on the jackshaft, which has the clutch on it. Then, the output of the clutch goes to a sprocket which then goes to my differential.

[ed1380]

@ russ- nope. no tags or anything. i havent taken all of the sheetmetal off. teachers are being anoyying PITA.


@kibble- o wow i remember that thread. holy carp that was a long time ago

[2or3wheels]

wow, electronics and i dont get along but, i have a bunch of those chapy remote control cars, could i use the servo for the steering for a throttle control? Im just going to try it on a motor on a bench to see if and how long it works but is it possibe?

[kibble]

Well, that's what I did. I have a servo on that engine. It's an R/C servo but it's not gonna be an R/C system. I made a circuit board that controls the servo depending on where the potentiometer is. The potentiometer will be connected to the gas pedal.

[timstar]

kibble, thanks for the info, very helpful.
