hey all i have a new thing with my TRX, i have it tuned pretty much perfect
now and i am much less depressed about it than i was, i got it tuned
correctly about a week ago and i was hoping this symptom would go away
When i start the engine it acts VERY rich i mean it wants to stall and if i
hold the throttle WFO the thing smokes like hell and jolts forward a little
every few seconds as the revs get high enough for it to try to kick into
gear. Then it just goes back down the revs - as you can see its acting VERY
rich then after i blip the throttle and rev it for about 2 - 3 mins the
thing can now move off. It's still slow then after the load of the Maxx has
got the TRX really hot it runs at its best. It will break away from the
ground e.c.t.
i ask about the above because my Torq .16 starts and you punch the throttle
and the thing wheelies off, you know its like 100% performance from the get
go. I don't know if nitro engines need warmed up none of my engines seem to
care except the TRX so i am just wondering it its just me.
funny thing number 2 :
If i run it for about an hour it goes "past" peak performance like its over
heating and losing compression or something the power is much weaker on the
bottom end but the top remains the same this means when the engine goes from
bottom end needle settings to top there is a hit the power is not longer
smooth which i like BUT the bottom end is crud by this time.
is anyone else getting these symptons, the piston/sleeve fit is still tight
when the engine is cold and the compression is good.
I ask this because it seems to me that if an engine would over heat, the way
i drive the Maxx it would either happen in the first 20 - 30 mins or never.
When my Torq was new it used to stall occasionally when it was driven hard
for a long time, but it was just because the idle lowered once the engine
was REALLY hot - but all my engines do that including the Maxx so i am not
worried about stalling i am just wondering does this mean something is
wrong?
