RE: Need Help Tuning Enya 45 CX TN Engine
Thanks to all....
Couple of corrections/additions:
Ed Cregger - this particular 45CX has the twin needle carb. Not ready to give up yet, but I'll let you know.
Sounds like a swith to 5% is the next step.
What confused me was that the idle speed pinch test gave me only a very slight acceleration before stalling the engine, so assumed the idle mix was not too rich. Should I get no increase in speed on the idle speed pinch?
On a full throttle pinch test I do get about a 1/2 to 1 second increase in speed, so thought that was OK. Everyone says it needs to run a little rich.
Also what seemed contradictory was the stall on throttle up (which I thought indicated too lean on the idle mix). At the same time the stalls when idling down after running for a period at 1/3 throttle would indicate possibly a too rich idle mix.
I don't understand the one comment about getting a reliable two stroke sound and not going so rich on the high speed mix as to have it four stroke. What is the difference in the sound?
Anybody know of a source for Enya plugs in the US that won't kill me on shipping handling?
