Mi1 Belt - Quite stiff

[roobeats]

Hi all

I am just in the middle of building my Mi1v2 (its a slow process as I only get the odd hour here and there)

I have just added the diffs, belts , spur and layshafts etc and bulkheads / upper deck and the running of the belts feels quite stiff, say if I turn the spur gear everything doesn't move very freely when turning it all tightens up at one point through the turn, any ideas if this is normal or what it could be?

Here is the manual I am on page 12 if that helps
