I have just had my first road run on my 1914 2 3/4, couple of teething problems to sort out but it went so well, after nearly 2 years of work i am so pleased with the result.
One thing that i am concerned with is the carb, Amac, the engine starts and runs with very little opening of the throttle slide, the air slide seems to be the dominant one, open a little to start and then use as throttle, when hot and traveling in high cog with the air slide fully open all the throttle slide seems to do is make the engine sound louder, yes the speed stays the same just the engine note gets louder, close the throttle down and it gets quiet again.
when i stopped i checked the throttle slide position, about 3mm above the spray bar, starts and runs in this position.
checked the float level, seems OK, just below spray bat, jet clear (28), inlet manifold for air leaks, timing, valve gaps, all seem OK and it starts and runs well, no black smoke so not to rich, only pops back if the decompressor is used,
Any suggestions that will help are needed.
What size should the jet be,
Had one thought, swap the cables over and use the air slide as the throttle, too easy but not right, want it right.
await your comments.
