if he has set a valve clearance to small it can cause the engine to idle up to shit, also to larger clearance can cause the same problem and create alot of noises up top, as for the timming, timming lights are cheap at Repco or whatever auto store you have close, check the timming at 2000 RPM.

set the valve clearances when hot to be a tight sliding fit for:
0.2mm intake, and
0.3mm exhaust.
this will be fine, but sometimes you may want to go a little smaller.
timing, start at about 12 degs, unless you are running ULP and then maybe a little less..
dwell angle?
smaller points gap = larger dwell = longer time for coil to charge.
set it to a sliding fit for 0.25mm. you could go to 0.2, but the you'd have to check it all the time.
0.4mm if you will never check it again
