Yes it will move, how ever when I try to WOT it struggles..The exhaust sounds muffled (best description I can offer) How can I tell if it is the slipper clutch (still new to this, sorry for the questions)

Jon....I can get it started it idles fine....I can rev it..no problem....When I WOT there is hesitation. I tried to lean it, no changes. Was not sure if it was bogging or just lose of compression

I have a Picco .21 that is crapping out (probably air leaks) for a T-maxx. I am looking for a replacement engine. I was told the O.S. .18 TM was a a powerful drop in and is easier to tune and maintain. Any idea what a good price should be for one of these. I have seen $190 - $230. Any help is...

Can someone suggest a good pipe for a Picco .21 t-maxx drop in? I currently have the standard t-maxx pipe that comes already installed. Price is open...but not crazy Tks

As I mentioned at the top of this thread, my T-maxx just all of a sudden stopped running. It has been extrememly hot here lately (wondering if that is the problem). I went ahead an purchased a larger cooling head (one reccommended in another thread). My question is how two set back to factory...

I have not...unfort not familiar how to do that...any suggestions

The engine has maybe 15 tanks approx. I am not familar with sealing the carb neck and backplate (not sure where the backplate is)

I am using the EZ start..does that change anything? I assume not

What does the one way bearing do? Sorry for the silly question.

Do you know the factory settings for the this engine?

What does the gap when the breaks are applied mean? .thanks again

I do have a temp gun, when I went to get it was 250. It is running rich (lots of smoke and fluid out of the exhaust. It was running fine, all of sudden it cut off. I tried to start it again, and it was idling low...very low. When I get it to idle for a sec or two I would rev it..a few times. At...

I was running my t-maxx with the above engine...running rich etc...it cut off. I thougt it was running too hot. Probably 280 ish.... Anyway I tried to restart, and it start running rough..When I rev'd it it sounded really rough and would not move. Full throttle and it sounded very slugglish. Any...

Thanks everyone...Jon I am not familar with sealing the carb on the backplate..can you clarify for me? Tks....I will look at either head. I figured that would help, but was unsure what head to buy..

Hey all, I have a .21 Ofna t-maxx engine . I noticed I am running 270-280 temp. I have been told blue thunder fuel will make this engine run a little hotter but that is what I am using and have. Can someone reccomend a replacement head that will help with the temp. I have the engine runnning...

ok so the hesitation (higher rev) is ok than? Yes my buddy has the sport maxx ( 2 wd forward only). My other concern is still the high temp. Anyone familar with factory settings on the .21 ofna maxx? Tks

Butter, I am not sure if your response was to me about the slipper. My friend has a sport maxx and he could just slightly pull the trigger and she moves. If I pull mine slightly it just revs...Once I pull it in enough she will buck (clutch engaging?) and she will go..not very fast. I want to...

I am having the same problem on my .21 Ofna Pic. Max engine. My LHS adjusted everthing to run rich so I can get used to it. I ran it today and the temp jumped to 260- 270. Any suggestions? One other question, I noticed I need to rev a little higher for the clutch to engage (4wd t-max). Is this...
