While I running my Savage 25 with Mach 26 engine and got through about half a tank of gas the truck lost about half it's speed and power like it was bogged down. It happened all of sudden. All signs point to the High Speed Needle but it was running fine during the first half of a tank. Help please

That could be a drive train issue as well. Did you inspect the clutch, tranny, slipper clutch, and diffs? Does everything move smoothly if you turn these parts by hand? If nothing is broken in the drive train it could be a loss of pressure in the fuel tank due to a blown line, cracked pipe, or cracked tank. I've also seen that happen from a clogged fuel filter before. Where you using fresh fuel, and how old is that engine?

It turns out that I had an air leak around the glow plug. Bought a new button head and the problem cleared up. Thanks for the help guys

Nice, glad it was a simple fix for you. I'll have to remember that one for future reference.
