I have a couple of questions about my sh28.
What are the factory settings for carb and what plug are you guys running in these engines?

Thanks ahead of time

Best you can run would be a 20% mix..........not Traxxas [&o]

Depends on the climate in your area for the glow plug, i'm running a medium temp GP, Mccoy MC8, OFNA medium or the best yet OS8 !
Needle settings are gonna be hard to tell, reffer to your manual (don't quite remember if it has the stock settings).

Hey bro, 2 1/2 out on the high needle and 4 to 4 1/2 out on the low should get you going pretty good. I would suggest a med - med/cold plug, os 8.

I run 2 sh.28's so far...both on os8's..work great.....

I find that my 28's run better on 30% fuel, NOT TRAXXAS 33%

With the exception of the 1/10's I have most of what I run are P3 .28's or 24.7's and the SH 4 glow plug works about the best. Go figure [X(] SH plug works in an SH engine

right on John...thats what they come with anyways..lol..were do u get em?

I run MC-8 glow plugs in my big block engines (.28 , .26).
