JERSEYHAWG / Glenn 4,487 #1 Posted June 6, 2015 (edited) Ok, heres a new one. Took the 854 out for a spin. After it warms up, maybe drove it about three thousand feet. It starts to sputter, miss, loose power. At one point it shut down, cools off, fires right up. Its got new everything, plug, wire,fuel filter, points, etc. Can someone point me in a direction? Has my a bit stumped,,,,,,,,thanks fellas.Glenn Edited June 6, 2015 by JERSEYHAWG / Glenn Share this post Link to post Share on other sites
Racinbob 10,299 #2 Posted June 6, 2015 (edited) Sounds like a plugged vent in the gas cap. Loosen the cap and see if that fixes it. Edited June 6, 2015 by Racinbob 2 Share this post Link to post Share on other sites
JERSEYHAWG / Glenn 4,487 #3 Posted June 6, 2015 Bob, my cap is new. I thought of that as there is no vent hole in the top. This replacement cap has been used by others on red square. My old cap, I still have it somewhere, would leak gas out from the tank and drench the top........I never could figure how this new cap "let air in". I guess as good a place as any to start. Thanks.fellas, who has a number on a differant can with the vent hole jn the top. Big thanks,,,,,,Glenn Share this post Link to post Share on other sites
JERSEYHAWG / Glenn 4,487 #4 Posted June 6, 2015 Here's the new cap. Seems to vent from the underside. I just dropped it to and dented it. Lol...what luckglen Share this post Link to post Share on other sites
Racinbob 10,299 #5 Posted June 6, 2015 That's how that one is designed to work Glen but maybe something is wrong with it that we can't see. 1 Share this post Link to post Share on other sites
JERSEYHAWG / Glenn 4,487 #6 Posted June 6, 2015 Took it for another three thousande foot run, kept the cap loose as suggested. Same problems. So the cap is ok. will check points and such again, but they were fine. These little gremlin problems are part of the fun. SometimesGlenn Share this post Link to post Share on other sites
Racinbob 10,299 #7 Posted June 6, 2015 (edited) Well nuts! It just couldn't be that simple. My mind is thinking possibly the coil. I've seen them act up when they start getting warm. Edited June 6, 2015 by Racinbob 2 Share this post Link to post Share on other sites
stevasaurus 22,234 #8 Posted June 6, 2015 (edited) It sounds like it is your coil then. Trade it with a coil from another horse. It has something to do with the coil warming up...kills the engine...starts right up after it cools for a few minutes. Happened on my 857.

JERSEYHAWG / Glenn 4,487 #9 Posted June 6, 2015 Was thinking like you guys said, coil. Who has a number,, might as well get a new one. It has not been replaced. Would feel better just replacing it. I bet you guys are right. Glenn Share this post Link to post Share on other sites
Racinbob 10,299 #10 Posted June 6, 2015 7................oh wait, you meant a part number for the coil. Here's the Kohler numbers 4151921S, 231281S, 231281, 4151921A There might be others as well. 1 Share this post Link to post Share on other sites
JERSEYHAWG / Glenn 4,487 #11 Posted June 6, 2015 Thanks bob, just checked flea bay, they want 25 bucks for used with probably problems. I will just get a new one and be done. No sense replacing junk with junk.Glenn Share this post Link to post Share on other sites
Racinbob 10,299 #12 Posted June 6, 2015 I definitely agree with that. I hope it solves your problem. 1 Share this post Link to post Share on other sites
stevasaurus 22,234 #13 Posted June 6, 2015 I would swap one first...they are not cheap. 1 Share this post Link to post Share on other sites
wallfish 15,937 #14 Posted June 6, 2015 Or try a new condenser. I agree with Steve, swap known working parts in there first to prove what the problem is. 1 Share this post Link to post Share on other sites
squonk 38,976 #15 Posted June 6, 2015 What does your fuel filter look like and how much fuel is in the tank. My 704 Vacuum fuel pump is weak. With a paper fuel filter it has running problems. If I put one of those red Briggs & Stratton screen filters on and keep the tank over half full, problem seems to go away. 1 Share this post Link to post Share on other sites

Mike, funny you mention that. But before I made the thread to ask. I replaced a perfectly good looking clean as could be paper filter with a brand new paper filter. Then I topped off the gas tank, darn near the top. My first things to start trouble shooting. Checked plug, spark, wire, connections etc. All the easy stuff. I am on the wave length of coil condenser. Thanks,,,,,,,,,,,,,,,,Glenn Share this post Link to post Share on other sites
Brian01 481 #17 Posted June 6, 2015 Hey, don't mean to intrude or steal a thread, but I am in need of a coil for an HH100 Tecumseh 10hp. If anyone has one they'd sale or know where I can get one that doesn't cost $199.99, I'd appreciate it..thanks Share this post Link to post Share on other sites
WNYPCRepair 1,875 #18 Posted June 6, 2015 Brian, I searched all over last night for your HH100 coil, the only thing I found was kits to modify it Share this post Link to post Share on other sites
Brian01 481 #19 Posted June 6, 2015 Well, I appreciate the effort anyways.. Share this post Link to post Share on other sites
Coadster32 793 #20 Posted June 8, 2015 I agree with Wallfish. A condenser will sometimes do this after it gets all heated up. (Certainly a lot cheaper than a coil) 1 Share this post Link to post Share on other sites
Brian01 481 #21 Posted June 8, 2015 Well mine is not getting fire at all lol, coils gotta be dead 1 Share this post Link to post Share on other sites
JERSEYHAWG / Glenn 4,487 #22 Posted June 21, 2015 Ok, I just had a opportunity to install the new condenser as suugested. Went for a mile and a half cruise, no sputtering, spitting, miss fireing or anything. Worked like a charm. And was the cheapest thing to try first Big thanks fellas. And as a side note, Many months back I asked how you guys do the white paint lettering on the hoods and such, I put the 854 hood on the 520 seat and decided to try out my medium point oil base white sharpie pen, worked great.so thanks for that tip also.......Glenn Share this post Link to post Share on other sites
