Question about why my tuning changes when I put the body on?

you will have more airflow to the engine with the body off, so if you think about it, the body will slow the airflow around the engine and it will get hotter. i would try riching the engine up 1 hour from ware you tuned it without the body. for this reason i always tune with the body on, then dremel hole in the body so can get to the high speed screw.

Dude NEVER EVER clean and reuse air filters all your doing is pushing the fine particles further into the filter. the price of a new filter is far cheaper than risking the price of a new engine.
also like it has been said before it sounds like the body is just reducing air flow
resulting in overheating.

its personal preference, some people buy new others clean the filter. As long as you clean it good enough instead of a good rinse you wont have a problem. Its prob 50 50 on the air filter. you dont wanna keep the air filter for ever and ever and just reclean it. every rebuild i buy a new pack of air filters. so i clean them about twice and they get tossed.

I would prefer not estimating on how much you turn it. That could take even more time. Is the whole around the motor big enough and do you check the motor temp before and after u put the body on? That may help answer your question.

The airfilter info is only his opinion, not a fact. If you properly clean and reoil an airfilter there is no diddference than running a new one. Filter oil will trap any dirt that may not have rinsed out of the filter any way, that is what is is made for. You don't replace the foam filter on a motocross bike everytime it gets dirty so why is an rc engine different??

I understand where your coming from with the motocross bike but think of the size difference.

Hey guys, I'm running a Kyosho MP 777 with an OS .21 VG Motor. I like to tune my buggy with the body off so I can reach the needles easier, but when I put the body back on, the settings are slightly off. I have plenty of airflow, there are holes around the engine and where I refuel. I'm assuming the temperature rises though, and perhaps less air gets into the carb, so is the general solution for this just leaning out both needles by an hour before putting the body on? Is there a simple solution, or is this a case-by-case basis? Give me some opinions please. Thanks!
As posted 1500000 times before....(sorry if you have seen these before, but some new people haven't seen them yet) KEEP THOSE FILTERS CLEAN!
...get em cheap on fleebay! Run the Hi-flow version on race day and use the standard flow for practice.
