Hello lads I'm rather new to nitro engines and I dont know if this is normal or not but if I go full speed and then let it idle it makes these blobbery sounds !
I dont know if its normal or not I'm guessing maybe the HSN is little too rich but I dunno !
hope someone can help !:) Car: Ansmann Virus 2.0/ Engine: AR .28 Big Block
 
If it makes a funny high idle sound after a wot pass then I would have to say that your HSN is a tad too lean

Ok thx I gonna try to rich it a bit more then but yea the sound is hard to describe but I found a video where it sounds kinda similar but in the video the engine makes that noise constantly while idling !
In my case it sounds only like that when I go from full throttle to idle. Heres the video: start at 4:30
 
I can't recall my cars ever making a blubbery sound quite like that. Engine starts easy but the idle seems to be high.
The engine could be running a little too hot / lean with no air flowing through the body.

One final note, this is a "no fahrting zone". Please refrain from all testfahrting.

Anytime your RC sounds like Chewbacca from Star Wars, you're running too lean. That's my guess.
Haha yea thats how it sounds like :thumbs-up:
Gonna try to richen it out then.Thx for your help guys !!

Yes, when I first got into RC I fixed it by richening it out- try it and see how it goes- Don't be afraid! :)
But use only small movements of the LSN or HSN-- think of a clock and move about 1-hour at a time.

When I said don't be afraid I didn't mean go 69 turns in, just said that because most people are afraid to damage it, but It'd cut out before you did damage...should of made it more clear :)

Yea I know I will do 1/8 turns I think my engine is just slightly too lean, gonna try it out tomorrow when I get my new pullstart !
I tried to rewind the spring on my original pullstart but I gave up after my fingers were bloody. :oops:
Any Tips on a easy way to do it ? :)

Your car should be starting 1st or 2nd pull if it's tuned correctly, as for tips- try heating up the head with a hair drier or increasing the idle :)
