Hi I just got a 1976 Puch Maxi. I removed and cleaned the carbs and put a temp gas tank and new fuel line. And on the first kick she started right up and ran like a champ. However the engine seem to be a little clanky. Sort of like the chain was making noise. I removed the screw from the side that was on the crank case where I assume there is some sort of crankcase oil. And I could not see any oil in that area. i leaned the ped to the side and still no oil. My question is two fold.
1)What kind of oil goes in there and how much?
2)How could it be so low? Is there most likely a leak or is it because it has been sitting for 15 years?
Any help would be appreciated!
