Hey all, I've been running my gas bike (66cc) for a number of months now, around 4. Anyways, its normal to be a bit rough during break in and it was but i seemed to have it smoothed out, engine purred and everything ran smoothly. Although recently I was in a hurry to mix gas, and without enough time I estimated and poured a normal looking amount of oil in my gas. I didn't think this would be to big of an issue as it was only for one tank, and I made sure it was still smoking so that it wasnt too lean. After finishing this tank off i now notice i have to open the chock all the way and slowly close it for the engine to even start, so i took apart carb and cleaned, checked float height, checked valve, fuel line, and spark plug. Nothing seems to indicate why this would happen as i used to be able to start it after a few pedals. After riding for a while (10 mins) it will run normally. I also notice that i cant just instantly give it power, or it will bog and die, instead i have to slowly accelerate for it to function properly. Any ideas on what the problem is here? Gas? air leak maybe(althoough i have checked a bit) Another thing, it doesnt sound like its running well lubed. a sort of grindy but not really griding noise seems to come from the crank, almost like a long ting or something.. Figured it was just dry or something, doesnt seem to affect performance. Oh and ANOTHER thing 
, the gasket for the float bowl came apart on one side, i jammed it back together cause i cant afford one at the moment (i kid you not) so could this make an air leak? is it possible to remove the gasket or will that affect float height?
