raise the wheel off the ground The run the engine at the lowest speed it will run smoothly Work the control arm 20 to 50 times slowly in both directions You should see the wheel eventually start to pick up speed then it will be impossible to stop it with your foot You have now purged the air...

Engine oil soaked rags will compost quite happily Engine oil soaked rags do not spontaneously combust Vegetable soaked rags are the ones that can spontaneously combust and it is quite rare . This is due to the bacteria that produce methane gas Same story with oily rags in a metal shop they sit...

The alternator just recharges the battery & runs the lights & fuel solenoid Most mowers will run fine without a battery installed at all if the fuel solenoid is clipped . The red wire sends pulsed DC to the battery to recharge it and the black wire provides AC to the headlights only . So the...

try loosening the fuel cap Sounds like a fuel starvation problem Would help if we got the make model & serial number of the engine

Is there a dent in the rocker cover ? Common problem is running into some thing , denting the cover with prevents a valve from fully closing thus no compression Also do the pencil down the plug hole trick to make sure the piston is going up & down . LEt us know what you find .

Apply nickel high temperature anti sieze to the bolt before fitting as they are notorious for corroding solid into the head And note they are socket headed allen bolts not std hex heads because you can not get a socket or wrench onto a hex head

The cheap & nasty check for blown head gaskets is to run the engine for 5 minutes, turn it off then pull the dipstick out If you get white smoke coming out of the tube the head gasket is gone As Illingne said, a very common problem with all intek singles I do about 6 or so a year. No specific...

Well Trev it is dead so you have to make up your mind if it is worth putting a new engine in it A new B & S will set you back around $ 2,000 ( Aus ) a Kawasaki around $ 1,500 for Kohler you will need to auction of one of your children A Loncin will be a little under $ 1,000 A B & S short block...

IF you post the numbers from the tag under the seat then we should be able to pull up a wiring diagram Two things easy to check is the main fuse & the battery connections at the mower I am assuming you did all the normal things like make sure the blades were off , parking brake was on & mower...

Remove the carburettor turn it sideways , hang it on some wire and see where the fuel is coming from What usually happens is the float needle clags up and does not shut off the fuel with then overfills the carb and leaks out of the air vent for the bowl which is usually between the carb & the...

At this time of year in the USA mice chewing through wiring is the usual cause

you do not need zinc in a mower engine that has single valve springs that you an compress with your old fella High zinc is needed for engines with double valve springs and high lift cams I really wish idiots who know nothing about oils would stop crossing between NASCAR requirements and mower...

You will most likely find one kill wire has fallen off AFAIK only B & S use external diodes between the magneto coils

Businesses have not given a tinkers curse about satisfying customer requirements unless you are talking about the top 5% of the market . As for the rest it is brand loyalty , BS marketing and price point marketing.

The one thing you re missing is engine balance factor Now I have zero idea if mower engines are actually balanced at all being that modern production tollerances are such that they probably can run without dynamic balancing. I ride single cylinder motorcycles and we go to great lengths to get a...

First bit is correct. No battery powered anything will reduce the overall pollution of the planet and many will actually make it worse although the actual vector for the pollution may change . The second part is 100% incorrect global warming is very real and it has been real for decades but...

On any mower I use the ramp of mu tilting trailer Engine off brake released if the hydros are good it will sit there and not move If the hydros are stuffed it will race away like Mulga Bill's bicycle

(y) :LOL:

IT is a highly flawed design from the start and both AYP & JD use it It was just OK on the older models like the LX Deers that had narrower wheels and not this idiot pretend near zero turn steering set up . There is simply too much load on the bushing , it needs EP bentonite gear grease , not...

Me thinks it comes from the days of oxy where the lenses are just a plain tint because oxy gives off mainly infra-red so no UV protection Arc welding filters are supposed to filter off UV & infra red And plasma cutting lenses are better still In any case I am not going to look at it because...

Are you using the key switch off the JD to run the Swisher ?

Sounds like a leaking fuel hose or you have them reversed Fill the tank and depress the purge bulb ( if it has one ) If air comes out the filter the hoses are back to front If no purge bulb fill just above the return tub in the tank and see if it runs till the fuel level drops to the end of the...

I do around 300 jobs a year when the health allows it 1 person sole trader & independent And that is individual jobs , not uncommon for some one to turn up with 3 or more items This excludes blade sharpening ( both mower & saws ) I could do more if I wanted to but headache customers get told...

Farmer tech in China CTS in China ( they sell via ebay if you ask them to list ) Made in China Alibaba ( not Ali-direct ) Stens, Rotary Prime Line I keep about 20 mower carbs in stock I keep about 50 hand held carbs in stock

It is a casting defect They can actually move through the alloy when it gets hot enough Flat heads usually do not have that much compression so it should not be a problem IF it worries you then Devcon aluminium paste is the best filler Next best is POR 15 metal filler After that there are...

One of the really good things about being allowed to use swing back blades I end up with boxes full of old dead blades to patch decks with Being that I Oxy weld I just tack the end then forge to blades around the complex shapes tacking as I go Then back for a full edge weld

Tygon is branded with their name and the grade of the hose Unbranded is yellow cellulose plastic and crumbles in a season or so .

Nothing happens till you run the engine The governor at rest has the throttle wide open So you do not see any movement apart from the spring going a little slacker .

That is why we are here to help & also learn. Like Star I have added some to my next electrical parts order . I found one listed for Cub and it was $ 42 wholesale so $ 5 worth is a good investment if I can charge $ 20 and save the customer $ 20 . Otherwise you are looking at a full loom and...

Yep used to use it every week on the petrol station dip sticks .

the only conspiracey there would be port official taking back handers to allow a dangerous ship to leave the port . When we had only governments running ports there were next to no vessel defect problems Then we sold off the running of ports to private enterprise and we have 3 or 4 major...

Just to put it in perspective when we raced the 500CC BSA we were using AMAL main jets from 495 down to 420 A standard petrol engine ran 190 to 240 so better than twice as much fuel And from memory ( 50 years ago ) we ran 15:1 to 17:1 . My diesel runs 22:1 And like everything else for speed ...

raise the rear both wheels off the ground and try to turn them If they turn in opposite directions then the clutch pads have rusted onto the disc or the pins have rusted in the caliper Assuming they do turn Remove the wheel Take a photo of the clutch noting where the springs go Remove the rod...

And I would give Xtreme a quick call to make sure that the end cap is correct Never seen one that was not D shaped so yours might be a hangover monday morning special .

And note just how clean that box is Dust in a hydro kills them in no time flat So clean, clean & clean again

Soldering the replacement will do fine. Usually they are just crimped together with the wire at the terminals ( cheap ) before the terminals are inserted into the plug If you have the terminals , crimper & extraction tool it is a 3 minute job Just remember they are polarity sensitive as is a...

Hard bore soft rings make for an engine that runs in very quickly . Most Mitsubishi engines are the same I use a lot of L300 vans and I have needed to re ring a few but never a rebore except for the one that a rod let go My fault of course .

And a forged or steel rod Both will require rebalancing of the engine Not too expensive for a buggering around project Get a racing head if one is available as they have a squish band designed to burn dope .

You get more power but you burn more fuel. The extra power comes from being able to run higher compression ratios

On some of the old flat heads I have needed to ream out the throttle butterfly shaft hole because it it oval and leaking air . I got a pile of small plastic bushes in a grab bag of stuff at a swap meet some time ago and wadda know one of them is a perfect fit for the shaft . I never buy carbs...

Governed engines usually run around 1000 rpm faster than peak torque The reason for this is as the revs drop the torque increases to counter the load that is making the revs drop in the first place So if that curve is the correct one for you engine then 2900 rpm is probably fine What makes...

No you were not But as it is a mower engine it probably will not matter The + 020 is a circle that is + 020" larger than the bore so you will nor get full contact pressure because the curvature is different Over time the rings will wear excessivly at both the gap and 1/2 way round then break...

South Africa did it during the BS embargo years Ethanol burns slower , needs a higher compression ratio to burn fully and bigger jets ( lots bigger ) because it is not as energy dense .

In a previous life I was partners in a specialist courier business and we had a lot of trade houses & production studios . Not because we were the greatest but mostly because we would allow them to open a new account for every job so they got invoices for each production and that saved the staff...

Thanks Star I have not been there for a while because that was on the old box and it can no longer connect to the WWW Hope I stored the password some where safe. My ISP TPG just sold off their emails section to The Messenging Company and now only 1/2 of them work and none work properly .

Measure the PTO shaft carefully as both B & S and Honda made metric engines for the EU and they have 25mm shafts while US ones are 1"

Got the last lot from India One of the motorcycle parts retailers .
