Greg F Posted August 29, 2016 Report Share Posted August 29, 2016 Hi guys: Got my new 1940 P10 and she ran pretty good. Decided to put in Stovebolts electronic ignition like I have in my P15. Ever since that, she starts great, run for about 5-10 minutes, then sputters and dies. Let her cool a bit, then starts and drives for a few more minutes. I put back in the original ignition, and still does the same thing. Have searched on the website and tried some of the suggestions, but at this point Im frustrated and going nowhere. Anyone have any ideas on why this is happening? Don't think its a fuel or ignition problem, may rebuild the carb next. Like they say, if its not broken don't fix it stupid! Thanks Greg Quote Link to comment Share on other sites More sharing options...
dpollo Posted August 29, 2016 Report Share Posted August 29, 2016 Have you changed the Ignition coil itself ? It almost has to be a heat related problem. Quote Link to comment Share on other sites More sharing options...
Greg F Posted August 29, 2016 Author Report Share Posted August 29, 2016 (edited) Well not with the original setup. With the Stovebolts it came with its own coil(took that one out, when went back to original) Will try that. Does seem to be a heat issue, as it runs well till warms up. Thanks dp PS. Amazing how may cars and trucks you have, lucky guy. Edited August 29, 2016 by Greg F Quote Link to comment Share on other sites More sharing options...
knuckleharley Posted August 29, 2016 Report Share Posted August 29, 2016 If it's not the coil,chances are you have a bad ground somewhere. Quote Link to comment Share on other sites More sharing options...
Jeff Balazs Posted August 29, 2016 Report Share Posted August 29, 2016 I kind of doubt it is ignition related since both systems have been tried. I think I would be looking for fuel starvation......especially since you say it sputters some before dying. Jeff Quote Link to comment Share on other sites More sharing options...
busycoupe Posted August 29, 2016 Report Share Posted August 29, 2016 Check to make sure that the fuel filler cap is vented. Also, if there is a rubber fuel hose connecting the hard line to the fuel pump, make sure that it has not softened and collapsed on the inside. Ethanol in the gas can raise hell with old rubber parts. Quote Link to comment Share on other sites More sharing options...
TodFitch Posted August 29, 2016 Report Share Posted August 29, 2016 What was the last thing you changed/fixed before it started acting up? That would be the primary culprit. When it dies, have you checked for spark? Have you checked for gas in the carburetor (air cleaner off, accelerator pump squirts gas)?

bobostski Posted August 29, 2016 Report Share Posted August 29, 2016 You could have a clogged fuel filter. I had a car where the junk in the filter settled when off but clogged up again after running for a bit. Quote Link to comment Share on other sites More sharing options...
Greg F Posted August 29, 2016 Author Report Share Posted August 29, 2016 Thank you gentlemen, I will try all your suggestions tomorrow to see if they help. Greg Quote Link to comment Share on other sites More sharing options...
medium_jon Posted June 23, 2017 Report Share Posted June 23, 2017 @Greg F: what did you do to solve this issue? Quote Link to comment Share on other sites More sharing options...
rcb Posted June 23, 2017 Report Share Posted June 23, 2017 (edited) It could be any recommendation above. Next time you run it and it dies, carefully touch the coil (only briefly). If it's burning hot, then it may be your coil. Beyond that, you might double check your float adjustment in your carb. Also, not sure on these carbs but on my tractor carbs there is brass mesh where the line runs into the carb. Sometimes those collapse and cause a restriction so you can basically run it dry but if you let it sit, it will slowly refill the bowl. So restarting shortly after it dies gets your a few minutes, but if you let it sit for multiple hours it would run for several minutes before running dry. It's the only things I can think of... I'm sure you've tried those, but I figured I'd mention it. Edited June 23, 2017 by rcb 1 Quote Link to comment Share on other sites More sharing options...
