1st gear not engaging

D DaSilva /

I have a 1977 puch maxi. It was running fine. I decided to put this kit https://www.treatland.tv/puch-gilardoni-74cc-cylinder-reed-kit-p/puch-gilardoni-74cc-with-head.htm and this crank https://www.treatland.tv/puch-two-speed-za50-super-stuffy-crankshaft-v2-p/puch-za50-crank-v2-large-133.htm. The problem i'm having is that it struggles to go into 1st gear, or not at all. if it does, its at a high RPM and gives a good kick. I'm sort of new to this so i could be called a noob. Any ideas on what is wrong?
