gaz097 Bronze Donating Members 1,752 Member For: 13y 5m Posted 24/02/19 08:22 AM Author Share Posted 24/02/19 08:22 AM Right new theory, as my stutter/misfire is quite inconsistent now and only happens at certain times. Only does it when it's hot. Like proper giving it a hard time.So either A.Heat soak. Probably quite likely. Or B. Fuel Cavitation when the second fuel pump kicks in. The reason I say this is the Hobbs switch I had here has a minimum setting of 10psi (and I have it set to 12), which is around when this stutter occurs. Or C. Coils are still I <3 Bananased and get worse when it gets hot. Link to comment Share on other sites More sharing options...

What keefy said can be taken into account here too. Get a giant single so you don't melt the motor if the second one fails. 1 Link to comment Share on other sites More sharing options...
