RMCIII 838 #1 Posted September 14, 2014 Needing some B&S advice....... If the members may recall, I just recently purchased a Bolens 4800 Chipper. Great, no wait, OUTSTANDING chipper! BTW. The issue is this.. It has a B&S I/C 8hp. engine.... The darn thing will NOT operate normally, until it is FULLY warmed up! I do not get it.... I have cleaned "everything" out on this. I have not left any stone "unturned". What is up with a B&S engine? It only takes 2 pulls cold to fire the "beast" up. But it takes 10 minutes to get the engine to respond to any type of throttle increase or decrease! < Serious, once it has run for 10 minutes, you can do whatever you want with the throttle, choke lever and it responds like you would expect.... what gives? Is this a cold blooded engine or am I missing something? Rob Share this post Link to post Share on other sites
Catmanii 36 #2 Posted September 15, 2014 Don't really know, but I had a Troy built tiller that did the same thing. It would start and run easy, but don't touch anything till it warmed up (5 minutes or so) or it would quite running. Finely took off the carb. and soaked it for 24 hrs in carb cleaner blew it out with air, put it back togather, and reinstalled. Run fine then. Share this post Link to post Share on other sites
squonk 41,017 #3 Posted September 21, 2014 Is this new or used? What type of carb fuel tank set up? If it's the style with the carb bolted to the top of the tank, I would replace that diaphragm that's between them. It doesn't like ethanol Share this post Link to post Share on other sites
rmaynard 15,425 #4 Posted September 21, 2014 I have a Briggs on a 5500 watt portable generator. It ran the same way. I cleaned and adjusted everything. Installed a carburetor rebuild kit. Better, but still not right. The only thing that fixed it was a new carburetor. I think it's an ethanol related problem. The new, replacement carburetors are made with material designed to hold up better to the damage caused by ethanol. 1 Share this post Link to post Share on other sites
shorts 182 #5 Posted September 21, 2014 The problem with the ethanol fuel is that the alcohol/ethanol is corrosive to the white metal in the carburators and erodes/changes the dimensions of the calibrated passages, bleed holes and jet openings. The racecar people that run ethanol hard anodize as much of their fuel systems as possible and then "pickle" the fuel systems with gasoline as soon as possible before storage to minimize corrosion damage. For my own personal small engines it is worth the extra cost and effort to find and use ethanol free fuel 2 Share this post Link to post Share on other sites

RMCIII 838 #9 Posted September 21, 2014 There are a couple but that stuff is expensive.... $4.99/gallon. Crazy prices on fuel at the marinas. Rob Share this post Link to post Share on other sites
Martin 2,131 #10 Posted September 21, 2014 Finding Ethanol free in Cleveland will not be easy. Rob are any of these in Cleveland? I'm not familiar with the area....... http://pure-gas.org/index.jsp?stateprov=OH this site is good but I've found many more stations in my area that aren't on the list. ask at the station or sometimes they have no alcohol/ethanol on the pumps. in my area at least 75% of premium pumps are ethanol free....

RMCIII 838 #11 Posted September 21, 2014 Closest is Strongsville to me and that still is a 25 minute drive. Crazy, but I think I may, just take the drive. Thanks! 1 Share this post Link to post Share on other sites
shorts 182 #12 Posted September 22, 2014 you can buy ethanol free small engine fuel at the hardware store for 6 or 7$ a quart or spend $5 a gallon at the marina , also check out leaded aviation fuel at $7 to 10 a gallon. If you are using a lot of fuel over a short period of time use ethanol added fuel but when you are done running the engine shot the fuel off and run the carb dry or drain the ethanol fuel from the tank and run a splash of real gas thru it and then run the carb dry. for my lawn stuff I just pay the premium price and buy marine fuel and keep a couple of 5 gal cans on hand, When I need to run the generator for a power outage I usually run on what ever fuel is available (ethanol fuel) and when the power comes back on I drain the tank, run the carb dry and then flush the fuel system with good gas and run the engine for 10 or 15 minutes and then run it dry and drain the tank until the next time it's needed. In myopinion the drain and flush proceedure is less time consuming and costly than the aggravation of an engine that won't run or run right when I need want/need it to run. The $ 1.50 a gallon premium price adds up to $20 or$30 a year for me and that's less than a carb kit and soak solution or a new carb. 1 Share this post Link to post Share on other sites
tunahead72 2,403 #13 Posted September 24, 2014 Martin, and everybody... The pure-gas.org site relies on guys like us to keep their information current. Feel free to add stations to their list. Which reminds me, my favorite station in Virginia isn't on there... yet. 1 Share this post Link to post Share on other sites
Martin 2,131 #14 Posted September 24, 2014 you are spot on Ed. I've added the ones around here that i use and updated some others as well. the importance of users updating and using accurate info on the site can't be emphasized enough. without testing the individual stations, its all anybody has to go by....... 1 Share this post Link to post Share on other sites
