BB?

[saltykillswitch]

I have the 2.5 4910 tmaxx and want to bb it what engines will take the ez start anybody know

 

[hulkmaxx]

No actual BB engines will accept the Traxxas EZ starter.

 

[saltykillswitch]

Well that sucks what's the biggest engine that will accept it? Or is our easier to just go 3.3?

 

[hulkmaxx]

Picco .21 maxx plenty of engine for any maxx or revo. Uses ez start.http://www.ebay.com/itm/Picco-P-Ser...704?pt=LH_DefaultDomain_0&hash=item35e6a9aae8

Just go with the 3.3, it's got plenty of power and won't break the bank.

If you want quality and still be able to use the cheesy start then the engine hulkmaxx suggested is an awesome one,...os .21tm is another quality mill that is a "direct" drop in like the picco.21 mentioned,..if you don't wanna spend over 200$ then the 3.3 like mentioned would be your best bet,tuned right with a good pipe and properly broken in the 3.3 really isn't that bad of a mill

 

[hulkmaxx]

Yes the 3.3 Traxxas mills are decent engines. But op asked for biggest displacement that a cheezy start would fit. Mostly stock components will hold the Picco .21 maxx, minus the drives shafts will eventually need upgraded to CVD's. My buddy is running one in a revo 3.3 with only a FOC and Traxxas steel CVD's, with no issue's. And the Picco will last a lot longer than the Traxxas mill.

 

[hotrodrob]

He also asked if it would be easier to just go with the 3.3

 

[hulkmaxx]

Oh well, then it would prob be better to go with the 3.3.

 

[saltykillswitch]

With my 2.5 I'm eating cvd. I just installed steel ones. Thanks for the help guys

You shouldn't be eating the CVD's with a little ole 2.5, you have an issue that needs sorted, how exactly are you breaking them?

 

[saltykillswitch]

I'm slopping out the joint holes till it drops them. I have the resonator and am running 33%

 

[hulkmaxx]

You should be getting a good amount of run time on the stock plastics with a 2.5.

 

[ThunderTiger]

sounds like hard acceleation and heavy braking causing the issue..

Could be wrong though......

 

[saltykillswitch]

Yeah u might be right. I drive it hard

What does it mean when the engine has a rough idle.

 

[ThunderTiger]

depends what you mean by "a rough idle"...

my revo used to have a "roughh idle" but that was down tothe glow plug and the idle speed screw being set so the idle was far too low.

 

[saltykillswitch]

It's like a lope to it. when the engine gets hot I can't keep tune it just boggs at wot till the engine gets wound up. Then progressively gets worse

When I was in cali it ran great and was running 30% blue thunder and ran out and bought some traxxas 33%. Got home to utah and now can't keep tune to save myself.

 

[ThunderTiger]

have you tried a different glow plug and followed the flow chart posted (somewhere) on this forum?

Boggig at WOT could be a case of either HSN or LSN being too rich or lean.

there are other things to consider such as sealing the engine with RTV against air leaks.

It runs damn good till this happens and once it does it. I can't get out out of it unless I wait for it to cool.

Unless there's a new air leak somewhere it absolutely sounds like a tuning issue. Different temp, humidity and altitude.
Here's the tuning link. Print the chart from the link below it and keep it with you.
