Flywheel has two timing holes?

[Fozzy]

You cant really get the camshaft 180 out...it only locks in one place... if you rotate engine a few times and re lock it, it can appear to be 180 out, but its not, just need to turn crank another turn...camshaft goes half crank remember so you have just stopped it at a different point in the 4 stroke cycle...

As for 2 holes, yes there is, but only one is the bigger size...you will know ur right as if engine is good, once its locked, the rest will lock off...

Cant view the video btw as bandwidth is exceeded...

So what happens if someone happens to have taken the camshaft out then turn it 180 and put it back in thinking it was wrong lol. looks like i will be returning that back tommorrow hehe.

Sounds like the pump timing needs retarding

So i guess i need to loosen the mounting bolts and spin the pump slightly? im going to say retarding it is to pull the top towards me so in affect the pulley moves anticlockwise?

Im new to all this mechanical xud engine so i know very little.
