I now notice myself experiencing what I think is valve float where the engine was revving higher but then dropping back down over and over again. I'm sure this is probably bad for the engine, correct? Anyone know how many rpm's I must be pushing based on the sound of the video below, and the...

Hi all. As I posted about a week ago, I wanted to pick up a doodlebug, so I did. Since I've purchased it, I've done porting on the stock engine, added a straight pipe to that as well, and other random engine things to wake it up a bit. This engine topped out at 39.9mph with my lightweight...

Hi all. I'm currently looking to pick up a minibike and I have about $350 to spend. Where would you go to pick up a good kit, without an engine or clutch? I already have an engine and a clutch so thats taken care of and not a factor of the $350. I've been looking at the Azusa minibike kit seen...

I'm looking to pick up a clutch for my briggs 6.5hp that I just bought. My friend has the Comet 1" clutch from bmikarts.com and I've heard its ok but not the best. His cost $40. Is this the best I'm going to get in my price range? Anyone have any other suggestions(or are there any you're...

My friend has a go kart which he just got running. It runs a 7.5hp Vanguard briggs engine and it seems a bit hard for him to lock the clutch and go, especially on grass or when he's turning. He has 22" rear wheels, 5.5 ratio, live axle, and the kart weighs somewhere around 150-180lbs I'd guess...

I know its a dumb question but I have to ask. I found a deal at a garage sale that I thought was really good to pass by so I bought it($55). It is a 900 series B&S 6.5 (thought it was a 9hp engine when I first saw it) 206cc engine w/ an electric start. same as this but with a 1" shaft...

Hey guys! My friends and I have recently created a contest video for a chance to win sandwiches for a year and a party for 40 people catered and DJ'd by Wawa. If you dont know what Wawa is, its an awesome convenient store, pretty much a combination of 7-11 and subway. The rules were to create a...

I recently picked up a 5hp Tecumseh engine in rather nice condition but I really need the cash within the next week or two so I need to let it go. I've completely cleaned it out and it runs fantastic. The governor gear has been removed and the governor linkage is able to be directly used as a...

I was driving out to lunch today, just left my house. This guy maybe 5 houses down from me was wheeling out a rather new looking Craftsman chopper/blower machine with a nice yellow FREE sign on it. I stopped and asked "Youre giving that away?" and he said yep! Tossed it in my car and went home...

After reading for a few weeks, and with just a handful of knowledge, I've decided to give it a shot at making a go kart as cheaply as possible(making the parts as simple as possible to get by, but safely). I picked up a harbor freight welder, I had some spare angle iron laying around, and began...
