Hi, Fella's
Having trouble tuning my .21 buggy motor. It idles fine, starts fine, blowing good smoke . In saying that when I pull on the trigger the motor blurts a few times then stops with a puff of smoke at the end. Using 20% nitro and a #6 hot plug from O.S
If there is any good tuners out there that could help me with the tune I will be very grateful. Cheers

what engine you have?

A #6 OS is too cold for 20%

Not the best motor I no but it 's what came with the buggy .21 SH or as they say s**t hot.
And with the plug I looked it up on the OS site for glow plugs and on it's scale for glow plugs a #6 plug is there hot plug
It was called originally the A3 hot plug.
Can you guys suggest then a better plug, and if the motor will run properly and get some good
use out of it. Then I can look at another motor any suggestions on a good motor at a reasonable cost of cause as having a family and
a tolerant wife ,money for me is in drips and drabs. ie an allowance weekly it sucks but family come first.

Cheers.

SH arent bad engines at all, they are actually pretty good engines. but sounds like your a tad rich. but its really hard to tune over the net without seeing or hearing it.

True

I'll start with leaning it out just a little and i will give an update after i do that

cheers.
