Default What engine is this?

I bought a go kart for $50 the other day. The engine on it had no verification numbers at all. I planned on making modifications on it later on. I need some replacement parts first. I just need to find out the make and model.

Heres some pictures of the block:

"really, a raptor. how can you tell?"

The exhaust and intake port is reinforced, most 5 hp engines do not have the ribs running down to the crankcase, yours also has a stubby end on the crankshaft, flywheel side. the normal recoil starter will not work with that. and the engine has a ball bearing PTO.

What parts do you need, I may be able to help. what type of kart?

i got it from a some guy that salvages stuff. the frame is bolted/welded together, its pretty sloppy. down some research on the raptor(probably not as much as you), just seems this engine did not belong on the frame it was on. At this point i'm trying to get some set screws out to remove the clutch plate. until then i don't know what i'll need to replace. I have access to a sand blaster and gonna try to remove what little rust is on the block with a electrolytic rust removal process.

You will remove the whole block with electrolysis, aluminum is dissolved in the tank.

I think you just sent me a PM, resend it please

PM?
small engines are never made of cast iron are they?
what would be a good way to remove what little rust is on with as little effect on the block?

Hey Sam, Mac is telling you to send him a private message (PM) so he can talk to you off line .

A lot of small engines were made of cast iron at one time , not so today .

A small wire brush along with some elbow grease may take off the rust you are concerned with .

Some of what looks like rust is probably just burnt on oil and grease. If you want to make it look pretty jhoward's suggestion of a small wire brush is probably the best.

In addition to dissolving in an electrolysis bath aluminum can be pitted fairly easily with a sand blaster.

alright, if i were to take a wire brush to it and some elbow grease, would it do as good as sand blasting would? would it damage my block?

What would i do to prepare for painting?

I wouldn't use a steel wire brush or you may be defeating the purpose as you will inbed steel particles into the aluminum which will oxidize leaving additional rust stains. Also steel wire will likely show deeper scratch marks more readily. Get a small non ferrous wire brush ie brass which is less likely to leave deep scratches the original finish.

I use media on aluminum only if I am painting over it as any media will ruin the finish. If you choose to go that route and have a small hobby setup, hold your piece away from the gun 12"-18" to limit the amount of aluminum material lost. Your simply trying to remove the grime. Also media gets into everything ie oil passages, valve guides, bolt holes, etc and is nearly impossible to get it all washed out without going through all the other processes as well.

I use a 5 gal of Berrymans carb cleaner and soak all my small engine parts in them to loosen grime and then rinse them with a hose or powerwash them. Chlorinated Brakeclean in aerosol cans works very well also but gets pricey by the can. Still cheaper than 5 gals of Berrymans unless you do alot of work on other projects.

That looks like a Briggs regular 5hp briggs fun-kart block to me. Didnt the raptor series engines all have the cast iron liner and no govenor? I know my raptor 3 block has the liner with the govenor boss casting not machined out. What is left on the end of the crankshaft looks like a torque converter. The "rusty" looking spots you see are actually not rust, just discoloration from heat. Looks like this engine got a little bit too hot at one point. Oh, and the stubby crankshaft was the type used when they switched over from not using starter clutches anymore. I think they did that switch at some point in early to mid. 90's

Thats what i thought. Didnt think rapter made there blocks with the governor in it. You dont want a governor in racing and i thought they were sleaved too.

When you go to build a racing engine i would really recomend finding a blockzilla block If your serious about it. This block you have here is OK just for tinkering and to have the extra "UMPH" So to speak over your standard cart engine. Which is OK. A cheap quick way to get a torquey engine is to swap cams. That would be a cam good on low end but would drop out on high end. I dont really know off the top of my head which cam would fit you. My suggestion would be to look up Dyno cams and see what fits your needs. It's cheap, effective and a quick bolt in. I really recomend a better block if you want to go further.

i don't plan on racing this cart but modifiying it to haul wood in a small trailer, or anything else i need. I extreme duty torque clutch would be good for that wouldn't it?

In that case you really dont have to do anything to the engine. You have enough H.P. to be sufficeint. Add a heavy duty clutch if you feel you want to but just a standard clutch would be good enough for pulling small carts, ect. lite duty work.
