smoke coming from cooling head

[sdeck777]

smoke coming from the bottom of the cooling head when i try to start it (t maxx 2.5)

The cooling head might be loose try and tighten that up and try again and if that doesn't work them hopefully some one else will know what's going on.

are you talking about smoke around the glow plug , check to see that the glow plug is tight, somtime fuel will do this as well till it burns off after getting warmed up. check the head bolts as well like duramax47 said to

My old tmaxx did the same thing after i tried blowing it up! haha

Get the engine warm with a hair dryer, then tighten the head bolts evenly, in a star pattern. If that doesn't work, you may have to take the head off, flip the shim over, then re-tighten.

i haven't seen anyone ask if his glowplug had the copper washer? i haven't had nitro's in years, but do they still require the copper washer?

 

[Metalhead Matt]

Yeah, good idea. Only turbo heads don't run the copper washer.

ok so i took the head off flipped the shim. heated it up retightened the head .. made sure the glow plug had the copper washer then retightened that. made sure all my batteries were good, checked my needles pretty sure they are at factory settings, heated the engine to about 160F and tried to start it.. it actually did start but it quickly dies .. the most it idled for was about 5-8 seconds

If you had an air leak before, you'll need to re-tune it now. Odds are, you had it tuned as well as you could with the leak, but without a leak, it could be way off.

someone on another site told me to try n put a couple drops of fuel into the carb >> yay or nay??

 

[alien13]

Shouldn't need to. If it's priming, and there's no air leak, you just need to make adjustments as needed.

Use this chart. Print it and keep it with your RC stuff.
