what kind of glow plugs can i use for my mgt .21

I would recommmend the OS A3 Plug

You can also use the mc-59 plugs or ODO99 plugs

i got the mc-59 and and it ran good for 1 full tank then it would turn on and as soon as i take the glow plug igniter it turns off

You will probably have to lean your HSN. leave the ignitor to keep it running and turn the HSN 1/4 turn

Was there plenty of smoke coming from the pipe? was it bogging? Or did it have a irratic idle and cut out on the top end?I ran the mc-59's in my .50 and I went through 2 of them in less then 5 minutes so I put the OS A3 plug in and it is great. The mc-59's are great plugs but with these motors I would run the OS A3.

it didnt bog it had very good throttle response

well get a new plug in it set it back to stock settings and go from there.

ok thenks

when i had my .25 in my savage i ran the mc-59's and it hated them.. wouldnt run worth the shit..
