Exhausted!

[kibble]

With all this talk about exhausts and stuff, I got to wondering if what I'm planning for my kart would be a bad idea.

My engine currently has the stock muffler on it which is a big, cube like device up on the top part of the engine. My thought was to modify it so that I had a pipe coming out of the engine and go down where it would split off into two separate, smaller mufflers. I don't currently have a pic of what I'm talking about, I'll try to get one soon. I'm just wondering if you guys have any advise about what's ok and what's damaging to do to the engine. The engine is this one.

Here's a pic of what I'm talking about so you can get an idea.

With a four-stroke,that shouldnt be a problem at all.If anything itll be really quiet lol.

 

[ironman]

where did you find those little mufflers at

 

[Russ2251]

Looks like standard issue 1/2 inch B&S. Hasn't changed in 60 some odd years. Part number 89966 among others.
Do I win the Golden Piston Ring?

ok so your going to put the little tube into the yellow one, tight.

 

[kibble]

@ Ironman, I got them at a local nursery. They have various parts there for lawnmowers and stuff.

@ Russ, Yeah, I had a feeling they were for B&S engines. You can have the golden piston ring.

@ 2or3, Yeah, I'm gonna trim 'em down a bit and weld them to the yellow pipe. I'm also gonna trim down the yellow pipe cuz it's too long. I want the muffler to be a little bit closer together by a few inches.

Those Subaru engines are nice! It'll probably respond pretty well to you opening up the exhaust like that.

 

[russo2]

what did you pay for that engine?

 

[kibble]

$50 at a Harbor Freight parking lot sale. This engine and an 11Hp McCulloch were on a couple of generators that were pretty trashed. Got both generators for $50 each and just took off the engines. I couldn't pass up that deal! They're functional, just needed some cleaning. Too bad none of you live nearby cuz the Harbor Headquarters has some pretty cool stuff in their parking lot sales. They have a bunch of stuff that may have been returned or there's something wrong with so they sell it for dirt cheap.

 

[2or3wheels]

well talk about location location location.

 

[I like karts]

Make sure you put a support bracket on there! It looks heavy.

 

[kibble]

They're really not that heavy but I would put on some brakets anyway, just so they won't rattle or shake around too much. Now that the kart is working, I'm probably gonna get on making that exhaust.

kibble
so you drove your kart lately hows it doing?Hows your steering doing on yours?

 

[kibble]

Well, I came across a small problem with my brakes but I figured out the cause, I just need a longer bolt for part of it. The steering is really sensitive and I think I need to shorten the distance between the steering rod and the tie rod ends. Might take it out to a school yard on the west end of town on Saturday and really try to open it up.

id say go for it on the exhaust plan! looks good

 

[kibble]

Thanks! Unfortunately I want to clean out my garage first before I get on that because I want to raise the kart up so that I can work on it. Trying to work on it while it's on the floor sucks and hurts your back!

Trying to get motivated to clean out the garage is the hard part. :arf:
