Sorry for the hi jack, but I have 2 simple Yerf dog Q's, figured this should be the thread to ask in.
1. What oil are you guys using in the final drive gears? Online manual I have says 4 OZs.80W90. There's a sticker on the engine that says 15W40
The oil I drained looks to be 15W40
2. Where do you fill the gear lube???? I see the drain plug, but there's no other bolt to fill it with.
3. Can the Howhit engine be bored for a 62mm piston? The wall is extremely thin by the timing chain already.
Thanks
