wheelhoss 2 #1 Posted February 19, 2012 I got a 418-a it runs for a bit then it dies. You let it set for about 20 to 30 minutes it starts up then it starts doing it all over again. The carb has been clean out I took it apart and clean it. Could it be the coil getting hot. Help Share this post Link to post Share on other sites
Sparky-(Admin) 19,677 #2 Posted February 19, 2012 After it dies you need to try to start it and verify whether it has spark or not. Dont wait 30 minutes but do it right after it dies. If it has spark then your coil or magneto is good and its probably a fuel issue. Mike............ Share this post Link to post Share on other sites

Don1977 604 #4 Posted February 19, 2012 If it is the coil braking down, you could check the spark plugs they should black with soot if it dies from weak fire. If the plugs look good it is something else. Share this post Link to post Share on other sites
wheelhoss 2 #5 Posted February 19, 2012 Could the fuel pump be losing its prime Share this post Link to post Share on other sites
Sparky-(Admin) 19,677 #6 Posted February 19, 2012 I think they lose it after sitting not while running. Mike.......... Share this post Link to post Share on other sites
Docwheelhorse 2,561 #7 Posted February 19, 2012 As soon as it dies take the air cleaner lid off and spray some carb cleaner in and try and start it. If it starts, runs and dies you have a fuel issue. If it doesn't start or even try then I would look at spark. Check the tiny hole in the gas cap to make sure you don't have a plugged cap that is causing a vacumn and the fuel pump can't pull fuel. If the cap chescks out OK I would change out the fuel filter.... the crud on a fuel filter can get stirred up and temporarily plug it. Tony Share this post Link to post Share on other sites
Kelly 1,028 #8 Posted February 19, 2012 I was going to say the same thing Doc, open the gas cap see if it starts back up after a few cranks, the vent may be plugged. Share this post Link to post Share on other sites

SAM58 30 #11 Posted February 24, 2012 Check the filter in the gas tank, sounds like a plugged filter... Had the same problem with a 520H. You can cut the filter off for a temp. fix until you can install a new valve & filter. Less than $7.00. http://www.rcpw.com/wheel-horse-fuel-shutoffs.html Share this post Link to post Share on other sites
