Hello, I would like to thank everyone in advance for the assistance. I have a Savage .25 with a OFNA .26 engine that keeps cutting out. It runs for about 30-40 seconds and dies. I am using OS 8 glowplugs and Traxxas 30% fuel. I have a D cell glowplug igniter and the rest of the system is stock. It will run and take a few turns and then dies.
 
Not too sure but id ditch the traxxas fuel. Run sumthing better like Odonnel or sumthing.

Dito, switch fuels. I ran traxxass fual also in my OS 30 and had tuning issues galore. Switched over to Trinity 20% and havent had to tune since, plus I picked up a huge amount of power.

Also, more info would be helpful. Are you idling, driving, breaking? Does it idle high or have a "garbled" sound when it starts. All this and more can help with the troubleshooting.
 
Is there blue smoke streaming out at mid speed? Actually can you get it to go fulll throttle without cutting off?
 
It sounds WAY too lean. Does it run like a top when it is cold? Then not start for a while after it stalls?

It will start and idle. I give it gas and it will make a few passes, then I go to turn and it stalls out. I have not had it running for more than 1 minute before it stalls. I ordered a summit to play with while I rebuild some issues with this one. I have considered converting it to electric but I like nitro and hate to give up on it. I bought the truck used with no engine manual, so I think I should find one and tune the engine again.
 
Yeah if theres also little blue smoke id richen it, it shouldnt randomly be cutting off at high rpms.

Richen your LSN a 1/16 of a turn and try again. Rinse and repeat until you eventually get to the point that if you sit at idle and got WOT, it should launch without hesitation.
