what block arre you thinking of?

 

[Snype2live]

i dunno thats why i was wanting some direction what would be the best block for the price of lets say 80

I can give you a crank for $20 shipped. It has 3/4" PTO shaft, in good condition. I pulled it from a running engine a few weeks back. Go for a cast Iron block with dual bearings. A Raptor 3 Piston, Arc Billet Connecting Rod, 94ss Cam, Dual Valve Spring Kit, Milled Head, Mikuni Carb, 3 Stage Header, and a lightened flywheel. A lot of lwn mower flywheels will fit, just have to look around, And they are VERY light!

like what kinda lawn mower flywheel and awesome as soon as i get the money ill prob get that crank from you

 

[solomon]

You have to pick around and find one that fits.

 

[Snype2live]

i mean like riding or push our what

I would not recommend turning a thin cast aluminum pushmower flywheel past 3600 rpm. There isn't much metal there.

 

[Snype2live]

so less metal that could potentially kill me if it comes apart lol just kidding

IDK, Russ seems to of had very good success with them. He claims they have never exploded on him.

ok will get u some ...ugghhhhhh!!!!!!!!!! i broke a bolt of in the pto side of the crank shaft

Now you get to learn how to use an EZ-OUT.

 

[gocart]

OK so besides the cheap project im doing im actually thinking about investing the money and buying a good block and building an actual racing engine so where and what would u recomend starting

Are you wanting to stay with the 5hp briggs "Raptor" style engine or are you considering going with an Animal? I personally like the raptor, since stock parts are abundant and cheap, but the animal looks like alot of fun.

 

[Snype2live]

hey i got some of those bits laying around lol now how to use them i might ask

 

[solomon]

you drill a hole in the broken bolt with a drill bit slightly smaller than the extractor. The hole must be PERFECTLY dead center and you put th bit in and slowly turn it counter clockwise, i use vise grips to turn the bit. If your lucky the bolt will start to come out. but usually these bits snap off when you got to extract the broken bolt and the hardened metal chunk gets inside the broken bolt making it even harder to drill out.

Those things are only good for screws stuck in wood.

 

[Snype2live]

lol well i just got a new crank shaft so yea and i chopped and lowered my frame today

 

[Snype2live]

so i came across a flat head engine gold mine i think i have 5 blocks now 3 of which are good 5hp blcks and 1 needs to be bored over and the other one is a 3 hp engine and all in pretty good shape just missing some parts here and there

 

[Snype2live]

I will not be limited by a rumor and have proven it. This is the kind of stuff by posted by folks who lack experience and common sense.
The last thing Briggs or anyone else needs is exploding flywheels and are over-built for that reason.

I must disagree. I have used those to extract many broken bolts over the years, including a starter bolt that had broken off inside the block on my Fiero. I removed the bolt lying on my back in my driveway using only a crappy cordless drill, and one of these extractors. I have never had one break on me.
If the bolt is well frozen, 1)Apply liberal doses of your favorite penetrating oil and let soak, prior to your attempt. 2) Drill a hole in the offending bolt using progressively larger bit sizes until the hole is ablout half the diameter of the bolt. 3)Use a hot wrench (propane torch) to gently heat the metal around the bolt, causing the hole to expand slightly. 4)Use a good quality extractor. You get what you pay for. 5)Select an extractor size that will go 1/2 to 2/3 the way into that hole. If you drill "slightly smaller than the extractor", you will likely break the tip off. 6) Turn the extractor with a decent tap wrench, a lot more stable and controllable than vise grips.
