Ok so I have a new DLE55 on a GP Pitts. I have 4 flights on it. First on went uneventful, second one the fuel line in the tank fell off, fixed that and third flight was good. Today I fly for 5 minutes engine running perfectly then all of a sudden it starts to want to cut out going vertical, then even in level flight and it flames out and safe landing. I go over and touch the motor and its is hot and not only that the aluminum spinner is really hot. I also richened it up 1/8 turn on the HS needle before. Any thoughts?
The problem is with the fuel system not the engine. A few questions, What type of tank setup?, What type of pickup in the tank?
No matter how much foam or insulation you have around the tank the vibration on the gassers will make the fuel foam, you will reguire a filter/pickup as fitted to ALL weed eaters/chainsaws to correct this, this will fix 99% of all fuel problems. Walbro make a great one.
You will need to run it slightly rich untill you have run around 1 gallon of fuel through the motor as they take some time to runin.
As has been stated, replace the DLE plug with an NGK this is done by the importer down here.
Cheers
