I was reading an article by the late Ron Paris, and maybe I misunderstood, but there is states, that when coming off a high speed pass, you should listen to the engine and it should have a slight high rpm before settling and if not to continue to lean the LSN......

Any help much appreciated....

Try raisng the idle or leaning the lsn. When you 1st start it does it idle?

lean the low speed ..you may have to also lower your idle after you lean the low speed...plug may be crapping out also if it wont hold a idle and the engine still has good compression

Let's narrow it down:

1)Brand new plug
2)Engine has very good compression
3)No air leaks

i saw this on neobuggy today,



- GRP stop engine production, focus on tyres?


Got Gossip ?
[email protected]arely 4 days after writing, "I am still runnning GRP engines at this time. we will see what the future brings but as for now still GRP." in our Live Q & A, Mike Truhe has switched to Orion engines for the remainder of the 2009 season. After Adam Drake's departure to Novarossi, it seemed only a matter of time before Truhe would find a new engine supplier. The Losi driver will debut at the Euro warm up in Austria next week.


always sad to see and eng manufacture having a tough time.

Bummer, The GRP's have been great engines for me. I am currently running the .21 &.28. I just installed new TKO ceramics in both engines last week. Maybe A guy should buy an extra p/s & rod before everything is gone.

Default fuel?

I'm just getting into 1/8 scale racing and just purchase a GRP engine. I was wondering is there a different in the nitro brands? Or should just be the same brand from my local hobby store?
