How are you releasing the tension on the blades if you have an electric clutch that is not getting power ? If it's not getting 12volts there would not be any blade action anyway. Make sure you have a good battery then check voltage everywhere - Not sue you'd get more than 12volts anywhere...

Make sure the shroud around the flywheel / coil area is clean so air can flow freely

It's not burning oil - it's losing oil somewhere and getting hot makes it smoke nearly all engines have small oil leaks when they have a lot of hrs running. Just add as needed until you find / fix the oil leak

None will be exactly , those are close enough and it should run fine. If you have one that is 50 percent lower than another you might have a problem - why were you testing compression ? is there a problem with it's running ?

A ticking sound would suggest something loose being effected by the fan,

Safety switches typically turn out of the fit 45 degrees or so and pull from the bottom , the seat itself does not need to be messed with , might want to post some pics

Not sure what a WC 33 engine is but a Tick is not anything to stress over , A knock however is a real concern

If it's a pully problem it would be constant , sounds like a belt slipping, pull the belt and roll each pully by hand and see if anything feels rough or noisy. Inspect the belt also to see if you can tell if it's slipping - it would be sorta shiny and stiff and not flexible

None are problem free - I've run Badboy for a while now and only had normal issues - I don't recommend getting anything with electronic fuel injected systems - anytime is has a problem it will need to go back to dealership. Just my 2cts.

What exactly are you saying " wont fully engage " ? If it's an electric PTO - it either engages or not - is yours a manual lever type that you engage ?

Been running a 54" Bad Boy for last 10 years - no complaints

I've gotten new carburators that didn't work well in the past, it's rare but still happens - you surely still have a fuel supply issue or carburation - I know if's frustrating but keep at it

You need to verify the ignition circuit is working, if this happened after your engine swap something is amiss in the wiring - use a test light and verify the switch is working properly

Sounds like a safety switch , you'll need to bypass at least the blade engagement switch -

If the carb was sitting up that long - not sure you can clean it well enough also the soft goods are probably shot. If it idles the engine evidently is in good shape so it's most likely fuel issues - don't think that model has a fuel pump only the pulse off the crankcase working the diaphram...

Make sure it's not a LH threaded bolt

Sounds like your electric clutch is goin out - Never had one fail before but I'm sure it happens. Can't imagine what else it could be

That's only for the ignition system - most are built into the flywheel- the " coil " is adjustable and should have a small airgap that reacts to the magnet on the flywheel and creates the spark and also helps charge the battery.

Is it an electric clutch / pto or mechanical shift to engage the blades ?

Not sure where the magnet is that you're speaking about but never seen a magnet involved in a starter bendix The bendix should engage when the starter spins up - there is probably a spiral on the starter shaft that makes it travel up to the flywheel then a spring to return it to it's original...

Little you can do except change them out again, when all the belts are off look at all the spindle bearings - spin each one and see if any sound rough or have slack. See if they're tracking properly and go again. Never seen them all go at once but you never know.

You can remove the seal pretty much any way you want , it's no longer being used so don't worry about destroying it in the process, I've pulled many by punching a sharp screwdriver or something and prying it out of the fit. Be sure and dress the whole area / shaft and seal fit with emory cloth...

Did it just throw them off the fit or are they all destroyed ?

I had a similar machine and had to drill a vent hole in the fuel cap. Also make sure your oil level is good, might be shutting it down when it's running via the low oil safety switch

I've found there are a lot o small gas engines that will " humt "with no load - it will usually settle down with the load applied.

Fuel for sure, pull and clean the carb really good - might pour a little into the carb and try it, probably will run for a bit before dying - float maybe hung up

Carb

It's Done - Get another same model , salvage all the usable parts of the first one and you'll have back up parts for the new, If I don't see blue smoke from the exhaust on a 2 cycle , I use more oil in the mix.

What's the history on this machine ? Has it been giving problems starting prior ?

He stated No Click when trying to start so thinking it's the Starter Solenoid

Solenoid is only used to engage the starter

put a volt meter on the wires when you engage the switch, Repeat with the engine running and wires off the clutch. Could be a bad or corroded connection or wires

Should read close to 14volts , you need to look at the wires from magneto to voltage regulator - should read 30 plus into the Voltage regulator , from there should read around 14 volts to the battery. There is a procedure on Utube to lay it out for you if you do a search.

Next time it does it , bypass the solenoid and see if it hits. If so, it ain't your solenoid

Doubt it's your shut off valve, probably trash in the fuel line / tank - blow back through the line - look in the tank with a flashlight .

Yep, that's what I found when I tore into one.

I think that model courage is badly designed , something came apart internally - that's what happened to the one I had - did a little digging and found out it was common with that motor to fail like this

Linkage ?

Anything close that has the same bolt hole footprint should work , I've used Kawasaki to replace a kohler before and it worked well, you will need the same sized diameter Crankshaft for the clutch and make sure the exhaust will have enough room to sit in that spot.

Pull the belt off the deck and see how they feel and sound when turning by hand , should be smooth with no noise , if you feel or hear grinding noise - there's your problem 20 hrs is not very much run time on bearings sealed or other. Check each spindle - I've replaced complete spindles and the...

I think there's a " pigtail" connection available with the OEM connector but I've used a couple of female spade connectors before with good results

Well if it comes and goes it's not a major part like crankshaft / rod etc. BC that sort of problem will not come and go The fact that it's not constant is hard to pin point. Post a couple of pics maybe so we can get a better idea of what you're hearing - Does it sound like it's at the top of the...

Your P TO wires probably got dislodged , if not there's most probably a fuse could be blown , put a test light on the PTO wires at the clutch and engage the clutch - doesn't have to be running you should see the light come on if not work back towards the switch / fuse etc. - there is also a...

Usually safety switches will keep the machine from engaging the starter. Why let the starter turn over and interrupt the ignition ? Cub may be different though

Spark plugs rarely go out , a fouled plug will look like new sort of shiny , a firing plug will be a bit gray and dry older plugs my look a little black but if they're firing the electrode will be dry and gray looking , Pull the plug hook the wire up and ground the threaded area while spinning...

It is part of the Governor system and you need a replacement or your machine will run away. Someone here will find a parts diagram almost for sure .

If there's no compression the head gasket is the least of your problems

I ran into something similar with a Honda machine, if it stops in exactly BDC the rod didn't want to break over - after forcing it to move off that spot- it's all good. Sounds like the same issue

These machines are poorly designed in my opinion- I've seen this too many times and usually not worth repairing, Replaced mine with a 23hp kawasiki - had to get creative with exhaust and clutch but it worked out fine - I think the footprint was the same

Drillin a Crankshaft might be a little tougher than it looks
