O.S 30vg will not start

[wallerboys]

I bout a used savage 25 with a O.S30 it would run for 5 to 10 minutes then stall out and would not restart but now it will not start at all. Anyone have any fixes

It could be a few thing's wrong @ the same time

check glow plug / & wireing connecting to glow plug for dammage

make shure engine is getting nitro fuel to carb & flow is good & no air in lines
make shure your glow ignighter is fully charged or batteries are good

check your needle setting's HSN & LSN check manual if you rig came with one when you bought it sometimes resetting needles to factory spec's with get engine refired

Try all thease tip & see if you can get Rig running

This is a textbook sign of overheating. How hot are you running? Richen it out and try again. You may have also lost compression. When it gets hot the sleeve and piston expand, however the sleeve will expand more, and if you have even a small loss of compression it will not start until the engine cools and the engine contracts back to its normal size. But richen it out gradually until you show signs of it being too rich (bogging, wont take full throttle) If its quiting on you, its because your running too lean and not enough fuel is getting to the combustion chamber and it stalls. And it of course overheats.
