Default Petter A ?

Hi everyone I could do with a bit of assistance, I have a petter A but from all the research I have done it would suggest that they only made them 1.5 to 3 bhp, but mine clearly shows 5 bhp. I have two theories for this; either that it was a special of some kind or that it has been miss labeled. if anyone has any ideas or has heard of a 5 bhp petter please do speak up.

Thanks - Noah

Interesting.

Some A types came in higher hp than 3 and normally had increased engine speed to get the extra hoss. The 1.5jp was at 750 rpm, what's the engine speed of yours? That could point to it either being a special or a mis-stamped spec plate, and also give Jim Perkins an email, he may be able to shed some light on it as well.

The engine speed is 750 and as i have just been looking i have discovered that there is a crude 1 scratched in front of the 5 so i recon this solves my problem :)

Thanks - noah

Reckon so, if it runs at 750 then it'll be a 1. 5 hp.....

Yep, it would have to be a fair sized engine to produce 5bhp at 750.

Most likely a 1.5hp that has been mis stamped. the 5bhp example would be 1650rpm.
