engine?

Inquiring to see if another member can offer information on Efenel Cobra mini bike. My question is the engine original. It is a Clinton 4HP Pull start not kick start. Any info appreciated. Thank you. Pictures are posted under member galleries.

I went out the other night with a friend on our Motovox 10's and the stock engine, we had a blast. We were able to get them up to 33 MPH. Anyone..

Just wondering if anyone can sell me a doodlebug engine for less than $75 shipped? It's for a motorized bicycle, and is my main transportation to work. I'm on a pretty tight budget as I'm only working part time (hopefully full time soon) and I'm just wondering who can offer me a doodlebug engine...

I see a local CL ad for a Subaru EX21 off a power washer for sale ($100) which is resonable to me as he said it works great, starts on first pull blah blah etc etc.. Anyway I have next to no karting experience and have that old MTD Yard kart and the '64 or '65 Rupp Lancer that I posted about...

I'll pay for shipping both ways, parts, and labor (within reason) if you can get my HS40 running. I've been messing around with it for a couple of months now and I've lost patience with it. I put an electronic ignition system on it, but still have the points and condensor. Right now, it...

I have a Sears Bird Duck frame that I am hoping will be my next project once I get my Harrison Wildcat done. I was wondering if it would be safe to tilt the engine forward so it looks more like a motorcycle setup? I have a few Tecumseh h60's and a Briggs 3.5hp that are likely candidates. Will...

Is there any way of telling if an engine is blown? I have a 6.5 horsepower briggs and stratton intek engine, I was riding my minibike and it suddenly stopped. Ever since then my engine will not turn on, I pull the pull started but I feel no resistance. It feels as if no spark plug was there. I...

Only numbers are on the shroud, and the first few are rusted beyond recognition. It was part if a 5 engine package deal and have no idea. Looks like it was off of a snowblower(electric start and no air filter). Hope the pics help determine this mystery for me. Thanks! Adam..

I have a stock db30 engine (98cc Lifan flathead) that I would like to extend the intake on. I'm wondering if anyone knows where I can get a flanged elbow that will fit the intake on this engine, which I can use between the carb and the engine. There are several reasons I want to do this. One...

Was not sure if this was the right place or not so I thought I would try. I picked up what I believe to be a heald trail bronc vt (3-5). From what I read it is the vt-3 due to it being the blue color. I love the bike and it has a hs40 which appears correct but wanted to ask you guys your...

Hello, all. I'm quite new to this forum, and to minibikes, so I hope I don't seem stupid. In about a week, I'm going to visit some relatives, and apparently, they have an old rider lawn mower that I might be able to salvage an engine off of. Apparently it has some carb problems. I'm hoping to...

Rupp roadster 1970 minitrail - Québec Scooters, minimotos à vendre - Kijiji Québec I'm thinking of buying this but i'm not certain it has the original motor. Does not look like a curved intake. My 72 roadster has a slanted intake for the carb. Could it be original?

Hi guys and gals. This is for those of you who have experience with these small engines. If price was equal which one would you buy, an intek 206 or a predator 212? It will be used on a drag minibike (not too serious) and it will get a billet rod, flywheel, header. The rest will most likely...

Im on my way to the store to get something WD40 kroil or something in the meanwhile I poured some seafoam on it

Anyone familiar with 1st generation Briggs World Formula engine, the one before PVL ignition/ flywheel? This one has steel flywheel and coil like Briggs 5hp Flathead. Original owner used it for kart road racing. It died when the yellow oil cap came off during a race, blew the oil out, and...

I'm using Shell Rotella T Triple Protection Full Synthetic Diesel Oil 10w30. Its got great wear protection according to shell's website. I just started using this oil, having switched from Royal Purple. Before that it was Walmart Supertech oil. Curious what others use in their 98cc Lifan...

http://boxstockproject.com/cart/index.php?l=product_detail&p=190 I am looking at this engine. It says 'some assembly required' what does this entail? I basically want a modified engine so I can drop it right on a go kart. I don't mind putting together a small amount, but I don't want...

so I know its super super hard to do without pictures and I cant get any but it is a 5hp or smaller hp the spark plug is angled into the engine it is a flat head, it doesn't have a pulsa jet carb just I guess a normal carb, and it was on a generator and had a tapered shaft

3.5 hp engine? Or is it bigger? This is my Tecumseh I'd # HS5-67016C SER 7124B. So the according to the sticky HS is horizontal small frame. I assume the 5 is 50 cubic inch. (Is that 3.5 hp ?) And in the serial # it was mad in 1977. Does this seem correct? I never knew the 3.5hp engines...
