Well my neighbor was getting rid of some stuff and I got a free lawnmower. It has a briggs 3.5hp engine on it and it’s a horizontal shaft engine. I tried it out and it won’t run. The engine won’t spark since that’s the first thing I checked after looking at some stuff online. Anyways, here are...

So about a month ago I flipped over in my go kart and the plate on the engine which has the throttle lever got bent. When I flipped over the engine also started smoking and then shut off. Now when I recently tried to start the engine it wouldn't start. So is there oil in the combustion chamber...

I want to later get a billet flywheel and I know they should be torqued to spec. I don't have a torque wrench.

So recently I purchased a set of used tires and they came with 3 hole tubeless rims. I have 4 hole rims (currently) and want to know what size hub I would need. Reason I am asking is the ones online are all 2-1/2 inch bolt circles but when I did the math (hole to hole is 3 inches) I figured I...

For a stock GX160, what fuel should I use? What octane rating?

I want to know how can I increase torque without increasing rpm. I did a top speed run and the steering was very fidgety. It made the kart shake a lot. Because of this I am scared of removing the governor.

I’m looking to eventually replace my rear axle as it is slightly bent on inebriate side. I’m wondering if an axle with a snap ring would be as strong as an axle that uses a nut.

So I have a 30 Series Torque Converter from OMB. The problem is that the torque converter is not reaching its final gear ration. It gets about 1/4 their then stops. I don’t know how I can adjust this. Please help me out. I want to go faster.

The chain I have stretched and now when I turn, the sprocket slides and the chain falls off. The key also wiggles loose. Also, the keys I have for my brake rotor is slipping and almost fell out. I have the rotor loose so it’ll float. I want to secure this key. So how do I tension my chain and...

So I installed some disc brakes I got from OMB Warehouse and they don’t work at all. I installed them and had the brake fully depressed but the kart kept on moving forward. Please help me out.

Hi, I want to know if there is anyway I can convert from split rim to tubeless tires. Thanks

So I finally got around to mounting my axle to the frame and what happens is that when the bearing holders are loose, the axle spins freely. When the bearing holders are tightened down, the axle is hard to spin. My bearing holders are on the outside of the flange rather than the insideZ don’t...

How does connecting rod length affect an engine's power and rpm. Is longer better or is shorter better?

I have a GX160 -haven't taken it apart yet- and I want to know how I can tell if I have a flat top piston or a dished piston. I also want to know if I can figure out if I have a UT1 piston or UT2 piston.

So continuing my research I know I need to get better valve springs in order to prevent valve flutter. I also want to get a better cam. I want to know if I should go with 22lb valve springs or 18lb valve springs. I also want to get a better cam. I see that in the description their is something...

So recently I purchased a used GX160 engine. I go to start it and it starts fine. The issue is that it cuts of after a while. I found that slowing increasing the airflow lever and slowly increasing the throttle fixes this issue. I want to know if their is a good setting where I should keep the...

Okay, so recently I was able to snag a Genuine GX160 engine for a pretty good deal. Now I want to do some mods but I do have a budget. What can I do to maximize my hp and revs using about $100. Any help would be appreciated.

So I am looking for engines for my go kart build and found a person who is selling 3 gx200’s. However, in the ad it says that the engines haven’t been run for a couple of years. I am wondering what kind of work I would need to do if I were to buy one of these engines. Any help is appreciated.
