Ok first my setup...

80 puch newport II

70cc Tomos Alukit

Home made intake with shitty welds (possible air leak)

Stock A35 reed block and reeds

12mm BING with 76 jet with stocking for filter

Hacked and welded Homoet 4p

Stock 50cc #22 head

somewhere between 40:1 and 45:1 oil

Ok the kits still in break in but after running it for a few miles between 30-35 when I back off the throttle is dies and wont start back up until it cools. When is does start back up it four strokes a bit with no power for about 10 seconds then runs fine untill it gets hot again and I back off the throttle.

I took the kit off to inspect it thinking maybe soft seize, but everything looks good. A little rich, but seems within reason. I am going to try more oil since it really should have more, that should make it about perfect. I don't know if it will help with that problem though.

I have heard also that it could be the condenser going bad. I would check this but I am not going to pull the plug to check spark when its hot and I don't have a spare plug (I know I know).

If anyone has any ideas I would like to hear it.
