More ultrasound and high pressure air. For stabilization use the Marine grade Stabil. B&S had a great product but it was discontinued for some reason - probably not healthy, like most. As for cleaning, Injector cleaner is good. Best product that does multi things changes based on new and...

I also think it could be fuel. The after fire solenoid on the bottom of the carb when dirty or weak may pull away from its spring loaded fuel shut off valve at 12 volts, but at cranking speed, you only have 9 volts and it may not allow fuel to main jet. once it fires and the starter current is...

99% of the time, the wire from the BATTERY TERMINAL YOU SPEAK OF goes to ignition switch post marked battery - buy way of a fuse sometimes. On the after fuse side is usually the output of the regulator or common tie at the Ignition switch. Then the run terminal of the switch feeds your common...

This is a very reliable simple transmission. The most common problem is the shifter shuttles from forward to reverse but need a bit of a roll to complete the shift. Try keeping pressure on the shifter as you slowly try and move. It should them complete the movement into forward position. If not...

This is classic and often never properly identified. When changes from toe in to toe out ie forward and reverse, I have found the axle itself is usually the problem with little fix. The axle tilts forward and backwards rocking in the frame cradle. Often caused by striking a tree or other while...

this statement is fact of the blue smoke with a blown gasket.

For hydro parts, need model of it on it.

Valves wear and a decompression system then does not provide compression relief, thus this is what he referes to on valve adjustment.

It is Kawasaki and look at the block pin pricked numbers or cast numbers to get the rest of the numbers. Failing to find them get the numbers on the carb.

popping may also be 1) mechanical decompression if so equipped, 2) sticky valve. 3) head gasket, 4) plug/spark. Where is the pop showing - intake or ex? I also did not check specs against the model but all B&S I have done ( many ) intake and exhaust valve lash are not the same.

No engine numbers means we do not know make, model type of start enrichment. Pulling slow on auto choke B&S models can give a bit of enrichment so that the vigorous pull will fire. If primer Tecumseh then prime wait 10 seconds and prime again. This has an advantage on some B&S engines as well...

Insufficient info but... that fuse may be the one that protects the battery charging system and if blown shortly after it gets running, then you had power to crank but then a short most likely blew the fuse and you now cannot start or charge while running,

When you say idle screw, are you talking idle mixture or idle speed? If it needs a choke, you most likely have plugage in the carb if no mixture setting makes a correction. There is also a service buletin on that carb system. Model info - means I do not research it.

I have serviced small engines for 55 years. NEVER found an engine damaged from any of the recommended oils in this conversations as long as the level was proper. An oil class I attended informed me that the US regulations allow anyone to call it synthetic even if it is not and the only way to...

Hybrids as mentioned will not take over the world for lack of raw materials. To bad cause it with the proper drive train has great advantages. static hybrids that continue to charge a larger battery bank and use a engine just able to get the car moving when battery storage is drained and have...

If it leaks when sitting and key off, the fuel solenoid only prevents the fuel from getting to fuel passages. Thus the float if can be gravity fed, can leak by and overflow. The carb has an atmospheric vent for the bowl, so the fuel overcomes the float and either comes out the vent or if the top...

Clean oil rinses the desired cylinder walls of the break in folded over microscopic metal peeks. Slightly used oil is always polishing surfaces while it provides lubrication. There is a balance to be had between over frequent oil changes and under frequent. B&S has now marketed engines that...

rate of growth due to heat causes valve lash settings changes. Exhaust is hotter, steel expands less than aluminum.

Shift fork is worn and therefore does not travel far enough to engage contacts or flywheel teeth mis meshed.

love it

Agree!!!!!!!!!!!!!!!!!! get valves adjusted.

By law a braking system is required. On BadBoy it is in the clutch. The clutch has an anchor to keep the base of clutch from spinning. This anchor is usually a pin on the chassis and a hole in the clutch body. After shut down, the spring tension system can slacken as the belt torque is in...

There are so many reasons B&S was top dog for years. They got caught by many OEM's who could not pay thier bill so they sucked them up. All USA competition still cannot hold a candle to the total of the B&S line which has a product for every class and is working to meet the on coming EV market...

I use simple green and LRC and water. Note: 2 cycle carbs - In my opinion are no longer rebuildable. It took me 2 years to make that decision 5 years ago based on the check valve either open or stuck closed due to ethanol. I rebuilt those carbs for 45 years with nearly 100% success until ethanol...

I have had 7 new carb floats act up! Float problems can be intermittent, particularly when not in use. When running, the vibration often stops the problem. Biggest thing we have done that helps tremendously is add some 2 cycle oil to the gas to lubricate the rubber tipped needle of the needle...

You are missing a cupped washer. see the IPL to find the parts. These systems do not work well new and are often removed totally by the customer. They wreck belts, parts wear quickly, springs break and assembly requires the step shoulder ,spring and cup washer to be assembled with out clamping...

I believe since your bulk order of gaskets a gasket change has been made.

Even a dirty air filter, and a few more like bad breather. Head gasket need to be proven in my thinking.

If a metal capped/covered plug connector that mounts to the base of the plug, it probably has a cracked insulator internal and the arc is coming out that insulator to the metal shield then to the base of the plug, never reaching the gap intermittently. A common problem caused by wiggling the...

So far so good unless the cable will be in the weather. Al cable will be greef if allowed to corrode which it will do even if dry but open to any air. Oxygaurd is a product that will promote conductivity and minimize corrosion.

most likely is missing a required key cause the wheel was removed and reinstalled pushing the key out un-noticed.

These starters are marginal. You said the clutch is on with key on. That extra drag will then reduce cranking speed to zip or so slow you will not have enough rpm for magneto to fire a spark. Fix wwiring for clutch.

Take it to a real shop and some engines need mods to have what you want - a throttle control. I did not research but based on " repair facility tried, they tried numerous flywheels, different carburetors and opened up the jet" - they may haved caused more issues than fixed!!!!!!!!!!!!!!

Give a dealer information to look up a replacement ignition switch and forget cobbing the beautify old beast please!

Good advise, and I would add that fix a flat fixes 70% of slow side wall leaks if you apply and spin to spread it on the sidewalls everywhere by going for a ride. Cost of complete wheel is almost always cheaper - period. Life is to short!

Get OEM belts - see another post " D125 stretched belt?

Yes belts are all over the place. So are applications and thier ability to accommodate belts of various specs. Some are very finnicky and some not so much. Also OEM's are often making belts at fractions and different vee angles to force proper fit to be an OEM belt. Then aftermarket copies the...

Good advise here. I would add, only generally 2 metals , ie aluminum or steel, magnetic or not. Additionally, I do not think synthetic an ideal oil for these engines except maybe I might agree for recent 2-3 year production where fits and finishes are better for synthetic. The size of the metal...

B&S will be here after we are long dead. The CEo's just took the money and ran. There production sales are booked into 2023! With existing engine and chassis information, check with a qualified B&S Dealer for an existing repower known engine option. If you go ahead with the overhaul...

CC=Cranking amps, CCa= Cold cranking amps. They do mean something. It is a rating of the battery to deliver amps and has a value to its depth of capability. Every battery manufacturer rates the battery either CCA or CA or both. Most low class riders have engines with cheaper starters and...

CAUTION!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Governor and throttle must be correct or you blow up your engine. Do not guess at this. Do not cob it. Fix it before even starting it or risk high speed devasting failure in less than 3 seconds.

The above is most likely the cause. If oil at the level of the piston because plug is doen hill or slightly over full, oil will weep past rings when stored before next use. If overhead valve engine could be he3ad gasket. All this is assuming the smoke is blue. One last possibility is float...

Either flywheel key partially sheared effecting timing OR intake valve to tight OR valve guide has migrated and valve does not close all the way. Since you said it seems to have good compression when you pull it over, either valve guide interference with piston or you actually have compression...

both a blown head gasket and a bad breather system will pressurize the crankcase ( in case of gasket ) or not create vacuum ( in case of breather ). One way to determine the culprit is a leakdown test. I suspect breather because you indicated the smoke came after a bit. Unless on a slope later...

Some Bronco's I feel have a major design flaw. Look at the carb fuel line elevation and the level of the bottom of the tank. If the tank is no more than about 1 1/2" above carb inlet, they run fine till the spring type fuel inlet needle gets some hours on it and then fuel delivery problems...

simple test: read battery voltage sitting quiet: "Static " voltage. Run and read again. If within tolerance of max 15v I would say all is good. You early said ok after new regulator, but then reading where curious but not really identified what readings.

iF THE CABLE MOVES FREELY, the problem is most likely the deck and most likely the brake system. Many times we find the cheap brake systems are the problem and it can be hard to detect.

ANYONE WHO FIXIES ENGIINES FOR A LIVING WILL TELL YOU THE CARB FLOAT IS NOT WORKING PROPERLY. OVER FULL WITH GAS WILL DILUTE THE OIL, DIRTY AIR FILTER WILL DILUTE THE OIL. i WILL NOT SPEND TIME TELLING YOU HOW, JUST KNOW IT DOES.

No, The opposite. The Battery is frying the system. Batteries can have an intermittent internal single cell short. Additionally, the fuse might be over rated. The output is protected by a fuse that will protect the diode. The only other option is a short on the way to the fuse. An ac pressure on...

You are possibly wrong, as MTD owns Cub. MTD designs thier belts wioth a different bevel than standard belts. Cub parts may or may not conform to standards or MTD design belts. Also OEM belts may have different cording weave or more cords or different material for better grip or more strength...
