Hi all. Looking for some guidance please.

I have rebuilt my D7B engine and now i am struggling with no power. I guess it is a timing or carb issue? I have stripped and cleaned the carb, changed the plug and set the timing best i can but still no power.

Can anyone give me any tips on getting timing correct ? Having the angled plug I’m struggling to get the correct BTDC setting. Any advice on this point?

Also what is the simplest way to set the carb? (Seems to run rich). I have set the pilot to 1.5 turns out. Ticks over ok but doesn’t want to rev very high. Again any advice on this point.

Thanks in advance for any pointers. Cheers

If you are having trouble with the measurement I would remove the head as being a 2stroke it is a simple job to do and you can measure more accurate.
