Never heard of it!!.. A guy says he has a 1PQMB 4Stroke clone engine scoot. He has an Airsal 4 T BBK and it won't work. Anybody know about or heard about this engine?? I told him a 1PE40QMB is the 2T Jog/Minarelli engine..but never heard of a 1PQMB.. Apparently he thinks it was a 60cc 4 T..engine. I have seen many TaoTao and Peace Sports 'secret 63' engines..but not one stamped 1PQMB..the just had a letter stamped on the back of the engine case. Help?  .. Glenn |

It has no displacement. The block was never bored according to the engine number.  Sorry, I've also never heard of this. |

Could it be a 1P39QMB? My SunL is stamped with a 'P'.

Or like Brent said..the cylinder was never bored from the factory..he just got a crankcase and solid cast iron cylinder with no piston. No wonder it won't run. Said he just checked it with a flashlight..I told him it was not a flashlight..it musta been a 24oz can of Beer...lol.. |

The B in QMB stands for 50cc. That's my understanding. A QMC would be a 60cc QMD would be 70cc QME = 80cc 139QMB = 1 cylinder, 39mm piston, Q=Horizontal motor, M=(I don't know), B=cc's So I have a 150QME motor in my scooter  |

M stands for motorcycle. It's a motorcycle style engine.
Q stands for forced air cooling.

I ran into some un-bored cases from China when I was looking for a cast iron cylinder head. A person would have had to buy 1,000 of them though.
Hmmmm, that reminds me to look for cast iron cylinder heads for a 150cc.
