First run of my JAP 34cc model "O" stationary engine [Part one]

impressive low revving for a 2 stroke, my jap (see my videos) would stall if i tried to run it that slow!

[caerleon87]

No! I have just watched your engine and i think it runs just as well!! I think my engine sounds like it is going slower than it is. I suppose it is going about 2000 rpm, these are only slow running engines anyway, max power is at about 2000/2500 rpm, one third of a horsepower!!

[77staggerlee]

Yes, I think you're probably right, the lower exhaust note makes it sound slower. Don't suppose you have any idea what model my engine is? I really know next to nothing about it! What would be the ideal fuel mix, horsepower, etc?

Didn't know J.A. Prestwick made two-stroke engines.

Hello m8

can you please tell me which spark plug you are using on this one?? can it be champion L10 or L86C or NGK 4510 B6HS.

also do you know which spark plug should be used on JAP model 2A?

Hi Paul, It does sound like it is running a little unevenly on this video, but i think most of this is because the engine is bouncing about on the ground. This is the same engine as in my other video "jap engine with base i made" and there it does run more smoothly. I think it is mainly just because it is a two stroke running with no load, but it might be running a little rich too. Thanks for the comment!!!

it is look like it gain the RPM while it is start becuase petrol intake start to pumped
