so, does anyone know the measurement specs on counterweight groove, and the rib it rides on??? i have .005 clearance... when i move it side to side it 'knocks'

i have a question... why, in the 04-s kit, does it have TWO needles??? it looks like one is longer, which tells me it would shut fuel off at a lower level.??? am i right?

so, if i have a gravity fed carb, i can remove the needle and seat, and install the pressure needle and seat in its place?

i will get that in the morning thanks

i will more than likely change the oil AGAIN after i figure out the problem...

I have an older Broadmoor...#1693840 with CV46016 hp Kohler . with a chi8nese replacement carb , the carb started flooding and belching black smoke when i was mowing the other day, finally quit 20 feet short of my garage. ordered a replacement chinese carb from Amazon... just installed it, will...

thank you very much!! ive been looking for a manual that covers this 31H777 intek...

Mine is at high limit on crank eccentrics... i didnt find ANY wear on rod or journal... interesting, i may put it back together and run it. i ran this mower at high throttle for 3 mowings ( about an acre each time) never skipped a beat, ..just that annoying low speed knock.when i saw the...

thank you, now i can find out if this is where my knock was coming from

that was not the problem... they were tight, i have the engine on my bench torn apart... my question was, where can i find measurement specs for these links?

i have this 18hp intek, model listed above... there is some (not measured yet) play in the counterweight links to crank journals... could this play have caused a low speed knock? similar to the sound a bad rod would have made? was noticeable more at idle to low rpms, than under full power...

i wish my problem would have been that simple

governor update!!! well, after 2 governor changes (both blew up) i believe i found the problem.if you notice the pic of the governor layin in the block, the shaft came out. i believe it was loose and moving the first time the governor blew up. and, leading to the "hunting rpm's" . after my...

i also realize it was a lot of time and extra work, but i never in my 45+ yrs of being a ,mechanic, was one to 'give up'. i wiull beat this thing...one way or another!

So, after tearing this engine apart for the THIRD time, with a gov issue... i found this in the sump/crankcase...i realize that governor shaft is NOT supposed to come out, but it did, and it ruined the new governor. have another one ordered... in the mean time, i put of some of my limited...

yes, i put new lines and filter on, and new fuel pump... pushes fuel out the outlet in a good stream. i have not done a volume test...maybe i should. i will do that, after i put the engine back together. thanks

the part that has me dumb founded, is this engine ran fine, although it had the rpm hunting before it went full throttle the first time... i just don't see, what changed...maybe ill find it when i tear it down

and thanks again for the link to manual... this will help me not go 'blind' into assembly. if this engine hits max rpm one more time, i may be throwing it on the scrap heap.

thanks for the info... according to THIS instruction, they are rotating the "control" (round piece). at full throttle. im assuming with some tension on governor spring. they are NOT holding the governor arm at full throttle... maybe i better try this way first... i checked and double checked the...

i might also add, this was an engine swap for a knocking 18 hp one cylinder. twin eng model 407777-0128-E1

Well, i guess it is time to pull the engine a 3rd time... after getting a new governor gear assy, gasket and gov seal. i checked and rechecked everything i can see with the governor... put the sump back on, set governor , held at full throttle with a cheater wire, turned shaft clockwise till it...

Ok this story seems to get nothing but WORSE... now, upon inspection of the gov gear shaft, i see there is no snap ring that goes into the case. also, i notice some galling right above the lower snap ring groove... my question is, is there a part number for a new shaft with both snap rings? the...

that was my initial thought, when i get this back together thursday, to limit the throttle at the carb... ill keep you posted, thanks for the info

i really think one weight was off when i started it the first time...

Update... i believe i found my errant governor hunting problem...parts are ordered... cant wait to get it together.

OK, so now i am removing this engine i just installed. i wanted to warm it up BEFORE re- adjusting the governor.. it went FULL throttle, i was afraid the rods would fly out before i could shut it down..i guess maybe the governor came apart, maybe it was failing last week? who knows..a teardown...

i will recheck governor adjustments...and post back a reply. thanks

this is a 20hp v twin intek donor engine from a junk tractor with the 2bbl Nikki with the black plastic fuel transfer tube and 1 main jet., it has been sitting for 4 or 5 years. i will check the governor settings again, both idle and high speed. and try to cheat the governor back a bit. it has...

appreciate your reply, so...how do i proceed to set governed idle speed? mine does have 2 separate springs...on attached to a fixed point on bracket, the smaller (idle) spring on a bendable tab , also, both these carbs have the single jet fuel tube (black) , so i ruled out one of those affecting...

also, most small engines have an anti-surge spring from gov arm to carb link... i wonder why these do not?

no change with choke, already thought maybe a bit on the lean side. and, as i said... this surges with a carb off a separate tractor that ran fine. im beginning to think i may have to pull the engine and check governor.

thats interesting... ill have to look for that, my only question being... why would the carb off a good running v twin act exactly the same

ok, i fixed one problem, over rich belching black smoke,,, now, i have an annoying surge...rpm rolls up and down, tried another nikki carb off my craftsman, whcih did not surge... same problem... i have adjusted governor, and checked linkages...could the springs be out of whack? i give up...help?

Great, i closed up those holes in the transfer tube... not, it starts and runs clean.. but now i have picked up a 1/2 throttle surge... now what? i have set , and reset governor ,,,, could the governor spring be weak? this engine sat idle for quite a few years

THAT was just my thought, i also have a Nikki carb on my DLT 25hp v twin. that particular carb has the white fuel transfer tube with 2 individual jets. i have some #9 shot in my reloading room, im going to plug those 2 passages and try it! thanks for the input

also, the gasket under the venturi is fine... checked that tonight...

i recently upgraded a troy bilt rider with a knocking 18hp Intek...with a strong & quiet 20hp v twin. it is belching black smoke, after a carb teardown and immersed in my ultrasonic cleaner for 2 cycles... i have found clogged passages in the upper main body before, but this one is spotless. i...

but, even now it seems i have strayed from the original problem in your post... "awful banging" noise... sounds internal for sure...

i was ready to pull the head, but my leakdown tester showed no leaks thru valves.. OR thru the oil fill tube. so i was certain valves & rings were ok. well, the only way to get "compression",,,, is there has to be a volume of air for the piston to 'compress"....you cant obtain that volume, if...

glad i could point you in right direction... id be very curious to know how it turns out

i just replaced a timing gear on crankshaft on a smaller 675 series briggs... had spark, key was ok... cam was out of time,,, just an idea

guess the pic didnt attach

i am really getting frustrated locating parts to recondition this not so bad Sabre i acquired. does anyone have a GOOD source for parts they have used repeatedly. i refuse to go to JD and pay their ridiculously high prices! i thought i would add a pic of the service tag, as NO parts sites i...

yes i am about to tear this apart, i have 2 Broadmoors with tuff torq's in them. as a retired mechanic with 20 yrs worth of rebuilding automatic transmissions, im not 'afraid ' to tear into it, it's more being afraid of needing parts, that are obsolete...or way out of my social security income...

thanks, thats what i was wondering.

tks for your reply, but my question was... the silver dollar size filter you mention, was that the screen in the fill port...or the filter under the pump inlet???

i'm curious, the filter you mention, was that the screen in the fill port? or under the pump housing?? i have a Broadmoor that wont climb inclines when warmed up
