anniversary4: hey Donyboy,
sometimes I think I am certifiably luny..I am hooked on your youtube
videos; watching them till 2 or 3AM on a regular basis. You do a great job
and are very articulate and knowledgeable as well. In any case I take
serious note of your cautions about not setting engines to rev too high.
What is the best source for determining factory recommended hi rev levels?
Any single doc for this?
q13855: Hi DonyBoy. I have a 3,5hp classic that seems to run at about double rpm as
what it is supposed to , no matter if I shut the throttel. Is there
anything else than the linkage you show on the video that I need to play
donyboy73: thanks you!
PhilQ1000: Hi Dony, I have an older Tecumseh HS50 on an MTD snow blower. I just
cleaned the carb (and actually went over the carb twice). It starts and
runs good, but only on 1/2-choke. When I open the choke fully, it dies. Any
suggestions? Thanks Phil Q- Pittsburgh, PA
ClassicTVMan1981X: Some people just tune their governors by ear... on most engines the tone
and pitch of it should sound like between the keys of "G" and "A."
POLOLOUS3: Do you use anything to test actual rpms, and if so what?
Tom Ellson: Ok thanks also I changed the oil had no idea what was in the machine befor
but I've put sa 10w30 but it had started smoking and giving off a funny
smell SOS for all the pestering comments
Anthony Browning: I think I have an old mower that this tip may ne good for.
Roy Lewis: Sometimes the simple fixes are the best fixes! You made it look so
easy....but that what professional do!! Thanks for the time and effort you
put into your many informative videos. Roy Lewis Buffalo, NY USA
ethan carter: youneed to replace the governor spring
Micheal Gabriel: i always look forward to watching donyboys videos !!!!!!!!!!!!!!
Kevin Isam: Hey,donyboy73 is it possable to put a push mower engine on a ride on? im
thinking of buying a ride on without a engine, the two problems i can think
of is how to control the throttle and how i would get the key to work, id
turn the key to on then pull, any ideas? i know slight electrical. and for
the throttle would i hook the "wire" to the spot the spring is on the
govener in thos vid? or do i hook it somewhere else, ANY info is fully
accepted and a video would be VERY helpful
donyboy73: can u tell me the prob again
donyboy73: thanks Roy!
tivon3: I made a mistake and poured Ford engine oil into my Lawnmower and now it
won't start. I'm guess since I poured it out and put the correct oil in it
still does not want to start. So I had to resort to using my weed-whacker
to cut the grass and boy was that grueling. Do you think I need to bring
the Lawnmower to the shop and let a specialist look at because I don't have
the tools to correctly asses the problem sense it's impossible to get all
the oil out by just dumping it over.
Dnuccio95ZJ: Hey dony, i have a husquvarna mower in the shop with a honda gcv160 engine.
it runs, but it runs really really fast. ive replaced both throttle springs
with brand new OEM parts. linkage is not binding. what could be causing
Randi Del Cecato: Hi Dony, I alway thought that Briggs made a bad decision on putting the
carb on top of the tank, they go through 2 many diaphrams and gaskets!
donyboy73: high speed steel or titanium coated should do, don't spin the drill too fast
Teddybear500: Thanks for the info!
gertwarringa: Great tutorials !
Chuck Norris: hi donyboy73 i have a honda hr 194 ive done every thing to get it running
but it is very hard to start and the oil is getting to the spark pluk wich
i intend to sort out next but the hi rev is like a low rev and idle is
switching the mower off the throttel cable has been replaced the other
thing is it clacks when you start it ive cleand the carb and tryed every
thing but it still dosent rev high enough and dosent start properly so if
you can help me or anyone els on here
jeffy0807: @donyboy73, the easier way to adjust the revs is to bend the tag that you
took the spring off towards the front of the engine, if you didn't already
L P: 2 possibilities , blocked jets , causing need for a richer mixture or check
gaskets , you could have a vacuum leak , closing the choke is blocking the
additional air source , depends if its running lean or rich
donyboy73: oh yes thanks, this is just one way of doing it
cory batzer: None of that was necessary because briggs and stratton designed it to be
adjusted by bending the linkage to decelerate and accelerate rpms
donyboy73: it's not recommended because the oil dipper is different on a vertical
engine and the carb would have to mounted horizontally
moofushu: I'm not sure my old mower needs this tip, but I'm glad I know what to do if
the speed gets too low.
Tom Ellson: Have you done a vid o how to adjust it because I'm new to restoring mower I
know some bits but not enough sorry if I'm a pain
donyboy73: no but jeremyfountain a youtuber has i think
Michael Mantion: I just bend the straight part of the spring with 2 needle nose pliers,
takes about 10 seconds. if you want it even shorter bend it more or in a
donyboy73: can you make a video of it running so i can see?
POLOLOUS3: I have a demo cut off saw, 14" gas 2 stroke. It was hard to start and run
for awhile. Took it apart, compression reads 40 psi, heard if you put oil
in spark plug hole for a couple days, will help restore some compression?
Should I just order cylinder/piston?
siemenstraffic: I notice the that mower was vibrating quite a bit, was it a bent blade or a
Marclugar Mkw: Hey Donyboy73! I possess also a Briggs & Stratton lawnmower (sprinting 375)
but I wanted to ask if it is possible to convert a horizontal axis because
I have a plastic fuel like you but it is connected to a spring and
Tom Ellson: the promblem is the mower runs but not high enough to cut the grass i had
it running with new oil earlyer and it had smoke coming from under neath
the engine( affter i adjuted the carb ) ive replaced the throtel cable to
see if it would work any better but the revs are no higer i adjusted the
carb ive posted some vids off it so if you wanted to see whats happening
you could have a look
tidymanr: Excellent video...I didn't know you could do this...I would have just
bought a new spring and wasted money. You are the man!!!
Tom Ellson: hi donyboy73 i assked you about my honda hr 194 on my other account but it
wont let me on so ive posted it on my other one named it (honda mower
problem reply donyboy73)so if you can help tht would be good ive only just
started restoring mowers wiv help frm ur vids but this one i cant get
running properly if i lived in canada i would bring it down but im in uk so
would appreciate help
kx80moto: quick n easy fix nice vid dony
donyboy73: you can use a tachometer for small engines or some auromotive ones work too
zx8401ztv: i did something similar to my old 3.5hp b&s as it was on the edge of its
limit to cut the grass, just a tiny bend to make the spring loop smaller,
works ok :-) Smashing vid :-)
99carnot: Very helpful, especially if you do not have a replacement spring. Thank you.
donyboy73: you need a new cylinder kit, the oil only bring up the compression reading
but does not restore it
knightrider1545: Will the spark plug get fouled or bad when you manually take the running
engine to full throttle, past mfg throttle setting?
donyboy73: you may need to adjust the governor on the engine
Chuck Norris: i will try to make a vid off it so you can see the problem
donyboy73: there should be an oil plug under the engine to dump it out
Tom Ellson: It dosent run fast enough and dosent start right
kodibass: Nice before & after, procedure! great vid!!
Dnuccio95ZJ: Great video dony, I might add that shortening the spring can also solve a
problem if your engine is surging up and down.
donyboy73: the blade wasn't balanced
Vet: When I graduated High School, all I wanted to do was kick back and relax without having to do any homework. But I realized I have no money to do anything fun. So I went to a San Francisco Vet School to get trained to make money. But seeing your videos, I am gonna be an internet marketer on the side. Let me know if you have any tips. Thanks.
