flywheel removeing from 14.5 briggs
Comments (3)The sheared flywheel key will not make a difference in removing the flywheel. B&S sells a simple, inexpensive puller that will safely pull your flywheel or you can make one yourself. Remove the crankshaft bolt. Remove the two studs on each side of the crankshaft holding the metal ring that secures the plastic cooling fan. Remove the plastic cooling fan, reinstall the crankshaft bolt without washer and run down to just above the flywheel. Drill holes in a pc. of flat stock, 3/8" thick or thicker by 1-1/4" to 1-1/2" wide to match the holes in the flywheel where the fan retaining ring studs were, drill oversize to make fit simpler. Buy two grade 8 bolts long enough to go thru the flat stock and 1/2" into the flywheel. Tighten them evenly, IF you get a lot of tension on them and the flywheel has not let go, hit the flat stock a good rap over the flywheel bolt. It may sound like you have broken things all to heck when flywheel lets go. Walt Conner...See More14.5 hp briggs & stratton engine won't start!
Comments (21)I recommend using a NGK BKR5EIX pt. # 6341 spark plug . IT will last 8 - 10 years depending on the hours per week it is used, commercially a good 5-6 years . The other problem is the fuel filter. An in line filter like a NAPA 3012 will filter out the the trash that the factory screen filter allows to get to the carburator. The carburator is another problem as water gets is the gas much quicker . Take bowl loose with a long pair of needle nose pliers & clean if bowl leaks gas may need to get the 2 gaskets to bowl. Make sure you have your model # . Fuel is another issue as there is more alcohol in gas these days . Premium gas may help if you don't use daily BUT the product that I have found that works best to disperse water in gas is REDLINE SL-1 fuel additive. 1 ounce per gallon will make the alcohol & water disapear. Exception to this would be when you see water on the bottom of the tank . In this case drain the tank first before cleaning the bowl of Carburator . Just a reminder to never leave the switch on when the motor is not running . Most 14.5 B & S have an electric switch that allows fuel to go through carburator when switch is on. If that does not fix your problems you have a spark issue , a valve clearence adujst hot or cold ? or broken connecting rod . Mechanical issues should be taken to a specialist !...See More18 HP Briggs & Stratton won't start - 'Is it Ignition?' - Help!
Comments (23)I have a very similar problem with a Briggs & Stratton 17 HP engine. I have put in a new carb overhaul kit. (The float was gunked up pretty bad, but now looks new, checked for leak or holes in it, found no indication that float is damaged.) Put carb back on engine. Engine runs, but poorly. It sounds likes it chugging, noticing black smoke out of exhaust especially at Idle. One thing I didn't notice in all the above posts. Is the adjustment needle on the carb an IDLE adjustment needle or a main needle? What is the initial setting? The engine does have spark. Although one spark plug shows more of an orange spark rather than blue. Both plugs were damp from unburned fuel when I removed them. (They are old plugs.) Engine running: It'll sit and run. I can drive the tractor. However when I slowly engage the mower blades (blades are new, bearings are good, belt is new) the engine dies, unless I quickly disengage the blades and apply full choke. Heading out to store to get new spark plugs this morning. I've already poured quite a bit of money in this beast. I may be the one who has a rolling ball of fire!...See MoreBriggs & Stratton 42A707 starting issues
Comments (2)Hi again! I have repaired the problem mostly. There were multiple problems, and one still exist. First, the flywheel key was sheared. I found that the flywheel was not torqued down properely. When I removed it, there was also a build-up of gunk on the tappered shaft and the flywheel tapper. I cleaned it all and installed a new key. Second, the starter had one negative brush wire burned off. I purchased a new set of brushes for $18 and this took care of the problem. It starts now, stil a little hard (turns over hard) but it runs very nice. There is some lifter/valve clatter, very little, but I know that it is to much. Later I will grind the valves and reset the valve lash. I wish they were adjustable like the older kohlers are. I want to thank everyone for the advice and for the exploded view of the engine and repair manual! I made copies and put them into a folder for future use. Thanks everyone! Ken...See Morercmoser
