Default Break in problem

Hi, Im breaking in a new O.S. 21 VG and everytime I remove the glow starter it stalls out. I tried running it with it on and it goes no problem. Please tell me what I should do to fix this. Thanks.

Either the mixture & idle settings are way off, the glowplug is no good, or the fuel your using is garbage.

too rich on bottom...the heat from the glow igniter is what is keeping it running.

i had this problem as well, it is because the glow plug needs to have platinum on it to allow for the fuel to egnite, the methanol in the fuel reactes with the platinum on the glow plug and allows the glow plug to keep inniting the fuel. just replace it with a new one and your are golden.

What plug you using, you should be ONLY using the O.S. P3.. you should only really run that in V-Specs.. I do and that is what they recommend..

Change plug, ok.
9 of 10, the factory setting is to rich.
You can tell if fuel is running from your stinger (pipe).

Preheat and many problems will be gone, a good plug will terminate many other issues, a fresh glow starter will finish of the other problems.

If this doesent work, and you have no indications the engine is running lean; lean the sucker

Default re

why not leave the igniter on it for the first tank?get some heat and time thru the motor wont hurt but you should never adjust the bottom end on a motor until the the high tneedle has been set proper period turn the idle screw in if needed may help blip the throttle and clear it out before you remove the igniter
