With all the other parts I got with the idler pulley everything seems to match up good. Had to get longer bolts and inside lock washers to shim the 🔩. The only question I have is to weather or not you have a special carb for the 2 stroke 66/80 cc engines.
Works better than just a fixed pulley
The moment I put this spring idler I could notice a considerable difference in the chain tightness. I actually thought it was too tight at first, Just had to adjust the spring spacing then all was good. Great product overall just wish it had 4 mounting screws like the original tensioner.
I enjoy all your products. Your a great product with a lot of choices. I will be back for more.
