Primary clutch problem

Had to buy a complete new clutch due to a bushing messed up on my old one and I broke the inside pulley trying to pull it off. Anyway ended up buying the right puller. Anyway put the new clutch on along with a new belt, and it pulls great, but I can’t get it in gear, when I do get it in gear when I stop its still trying to pull and lugs the motor down and kills it. When I was messing with the old clutch we tried stretching the spring out thinking it would help. Anyway had to use that spring in the new clutch. My question is, me trying to stretch that spring changed the length of it, could that be the reason it’s pulling all the time?
