I used to run my P5 around 240-250 with no longevity problems. They really do run hotter than other motors, but they last just fine like that.

Ahh I was turning 1-2 or 3 hours at a time...Way too much I guess.
Thanks I did not know these carbs were so sensitive.

I could be off but I think you have your tuning lingo is wrong. One hour means 1/12th of a turn. Basically 5 minutes if you want to get techinical. One hour is not one full turn. You should be making adjustments 1/12th of a turn at a time. I usually do a blade with of the screwdriver at a time, if you are far off this will take for ever though. A p5 should run up to 260 with no real issues. I don't even use a temp gun anymore, I just lean it until it starts to make good power and don't go much further. The more you do it the more you'll get a feel for it. The engine should clear out nice and sing down the straight. If you like the way it runs at 240 you are well within the range of safe.

you definitely can't turn one 3 hours. You will be out of wack quick

Backwoods engine fix
My P5 was toast after a re pinch it lasted 1 gallon the guy that did it did not polish the piston and sleeve so the scratches on the back side of the piston were still there only making the problem worse. So until I get a new motor I have taken the sleeve and wet sanded .003 off of the top of the sleeve then put it back together. Instant compression it runs now hopefully it will get me through the weekend that's all I'm asking of it. Then I will buy a new motor.

Hello, someone tried the Keep Off 7 with 2096 pipe? Or is it better 9901 for this engine?
Thanks. Best Regards. |

Roma
Anyone running the Roma just want to get an
Idea what carb insert you find best and how close To flush have you got both needles at? Cheers |
I'm using the 6.5mm venturi (blue color), and the two needles are nearly flat. But the needles also depends on the weather.

Is it normal that my P5 XLT needs a new rear bearing after 1.5 gallons or am I doing something wrong?

rear bearings can be damaged by poor quality fuel....rapid RPM spikes while engine is cold...improper breakin of the bearing.......Over revving the engine..... running too lean....... |
