Hi I my cylinders were bored out 20 over. Now do I have to increase my main jet by 2 sizes?? and also when assembling the engien do I ssoak the crank in 10 30 oil and coat the rings and cylidner walls with 10 30? Thanks
If you use oil on the pistons, use 2-stroke oil. Otherwise that white motor rebuilding grease works xcellent. No need to soak the crank, although that wont hurt anything. Just squirt 2-stroke oil in the bearings.
