I want to use a riding lawn mower engine and trans to power my new go-kart. The go kart will be used mainly to pull boat trailers, so I need some torque out of this engine, but I would also like to have a cruising gear. Any suggestions?

errrrrrrrr i dont no depends wot cc engine u hav init al ready lol tel me and i can tel u ;)

I took an old flat-head lawn mower engine, cleaned it up, cut up, painted it, and gave it to my son to play with.

i want to know how to replace a push-rod on a riding mower engine that's a v twin and where can i get a replacement and know which one i need. and how much (approx) will a push rod cost for v twin engine

Here is the easiest way to show you. Get the make and model number off the engine and go to outdoor distributors. com. Locate the engine model and it will show you an exploded view of the engine plus parts and part numbers. This will give you a good idea of how you have to go about replacing the push rod. With the part number you can also look up the part and the cost on the same site. It won't provide torque specs or valve adjustment numbers. That will have to come from the engine manufacture.

I have a 1987 model Snapper rear engine rider and I have a replacement engine ordered for it. I have been told that there is a keyway at the end of the shaft coming out of the [vertical] engine. If I remove the mounting bolts, will the engine slip off of the top of the pulleys, or how much work will be involved? I am somewhat of an auto tech, but when it comes to small engine replacement, I'm starting from scratch. It's an 11 hp vertical Briggs engine. Any advice is appreciated!! Thanks in advance!!

Swapping engines on a scale of 1-10 is probably around a 5 - not hard, but theres some stuff involved. The rear engined tractor is a bit tougher, with all the mechanicals located at the back, but it can be done with normal tools.
First off id reccomend taking photos/drawings of linkages/belt paths/ect before taking anything off, to help with reassembly.
The wires from the starter motor, and charging system need to be unhooked, the fuel lines ( gas should be drained out) and throttle/choke cables need to be unhooked, since the old motor is no good, id drain the oil out of it ( ive tipped one over- its a mess!) to be on the safe side. Pretty much the only thing left is removing the motor mount bolts, it might be easier to either jack it up and block it or since its a Snapper - it could be stood on end and easily unbolted. The motor and drive plate/pulley should come out thru the chassis.
Once the motor is off the tractor, you'll have to remove the pulley/plate to put on new motor, theres a small allenhead screw holding it on the motor- loosen that , it might be a bit tough to pull off, but it will.
When putting on the new motor, use a light coating of never seize on the engine crank end, so if it needs removing later- itll come off easier. Remount the motor back on the chassis, and reattach all the linkages/hoses. Id suggest a good high quality SAE 30 motor oil and using a new fuel filter on the fuel line. The only thing that might be a problem is the charging system wire - you might have to splice it, depending on the wires from the motor and chassis. After the first mowing- to be sure , just recheck all the engine mount bolts- check it over.

It was put away for the winter.I changed the oil and spark plug.When started it did a lot of sputtering but smoothed
out by pulling the choke out a bit.I let it run a while and when I shut it off, it backfired very loudly.I am just learning about small engines by trial and error.

too much gas, fumes dont ignite in cumbustion chamber and flow out the exhaust where they are exposed to high heat then "explode" causing backfire.

I didn't hit anything, I was on an even patch of lawn and there was no real noise when "it" happended. The gas pedal has no tension at all now, where before there was normal "tension". What happened? Is it the transmission? What can I do?

It could be driven by a belt. You may have broken the belt.
