Ok I need help with an engine for a GP Venus. I originally planed to use a .52 2stroke but after it was defective out of the box and I sent it back and it came back saying "Don't run your engine in dusty areas, the crankshaft was nicked" even tho the engine was simply removed from the box and then repackaged for warranty work. Then when I got it back even after a gallon I never could get a reliable idle (it siphoned a little - so I installed a pump just in case) and it still was way too wavy at the low end and I tested for air leaks...

So - what engine combo did you use in your Venus that didn't require a regulator to keep it from siphoning while being inverted. The tank is quite high in relation to the engine. Looking for a .46-.52 2stroke or a .70-.72 4stroke and wanted opinons on what worked well stock with the stock fuel location.
