meadowfield 2,570 #1 Posted June 29, 2020 Over the years a few of my k series have become sluggish to start and miss at high revs. The C-101 in particular suffer from taking a long time to draw fuel and misses - running better with a little choke. It’s a challenge to find a good cast aluminium pump, most of mine have had water in and the two valve seats are often really corroded making the pump inefficient.... I’ve tried at least 3 cheap plastic pumps. They start off well and all my issues go away. However within weeks I will find that I can’t get the tractor to start - working through it’s always lack of fuel. Each time the pump just fails to either draw or pump - priming it helps, but it still doesn’t work right. I once wired an electric pump under the seat, however the noise Was unbearable - as well as the size of the thing. so looking for inspiration on an effective replacement - has anyone ever tried a pulse pump from a later engine and tried using the crank pressure? thanks Share this post Link to post Share on other sites
ebinmaine 67,498 #2 Posted June 29, 2020 I haven't tried either one but I'm curious to see what others will say. I do remember reading somewhere about using a modern pulse type pump. Don't remember how they went about it. I'm sure you're well aware of this ... electric fuel pumps vary WIDELY in the amount of noise they make. Just wondering if a different type of electric pump would suit your needs better. Or, possibly, mounting it in a different location to change the type of vibration given. 3 Share this post Link to post Share on other sites
meadowfield 2,570 #3 Posted June 29, 2020 well I just looked up using a vacuum pump... I thought this video was a joke at first but he's just shown me how to do what I was planning - though I have a neater way planned of execution. btw is this guy for real? this is the kind of thing we would see on a comedy show here. 3 Share this post Link to post Share on other sites

I haven't found anything that is discrete and quiet enough yet... my briggs twin has a pulse type - My Kohler magnum has a breather pipe from the breather behind the carb - so not hard for me to borrow one pump and try on the other! 1 Share this post Link to post Share on other sites

squonk 41,118 #8 Posted June 29, 2020 The Facet pump ( Napa # 610-1051) is small, quiet, draws low amps & is reliable. I can hardly hear it run on my C-160. I do not know what the equivalent would be in Jolly Ol' England. 3 1 Share this post Link to post Share on other sites

pfrederi 17,739 #13 Posted June 29, 2020 Your engines must be very very quiet. I hear my electric pumps clicking (Facet Posiflo) when I turn the key on. Once the engine is running there is no way I can hear them. Pulse pumps carry a rick that when the diaphragm fails you suck gas into the crankcase. 2 Share this post Link to post Share on other sites
pacer 3,169 #14 Posted June 29, 2020 "I hear my electric pumps clicking (Facet Posiflo) when I turn the key on. Once the engine is running there is no way I can hear them." My 4 pumps are like Paul sez, In fact, as a rule I pause a few seconds to make sure I hear the clicking then when started ... nothing cept engine running... and the mower deck, etc. I dont have the Facet pump brand, but they are a copy of it. Had 3-4 of the round ones and they failed quickly but the Facet copies are holding up. 1 Share this post Link to post Share on other sites

I know fellows that have been in his videos and they say he is a very sharp guy on small engine repair. I know his antics are sometime very dumb if not stupid, BUT....he does know how to fix things. If you can tolerate the "goofiness'" for a short time you will find him knowledgeable and entertaining! I too am looking for an electric fuel pump for my 312 H...bought a new (cheap) one and it lasted maybe 2 hours worth of mowing....going electric now! 2 Share this post Link to post Share on other sites

I'm a yorkshireman (ask Norm - aka Stormin what the means) so try to do things frugally sometimes to make up for the bigger spend elsewhere - i.e. I've just spent $250 on sandblast/powder coat and tyres If you can point me at a cheap chinese electric pump thats not the size of a Kohler coil then I might take a look...

oldlineman 1,481 #22 Posted June 29, 2020 Ya what squonk said, I replaced my mechanical pump on my 1989 414-8 and I will never go back to a mechanical pump, I used a Facet pump a little pricey but you only get what you pay for. Can't even hear it when engine is running. I will never use a mechanical pump again instant starts every time! Bob 5 Share this post Link to post Share on other sites

Cleaned them up as best I could, applied a little JB Weld and installed the valves and clamped them in place. Once it set up the pump went together and has been working fine for several years.
