My Chinese PZ30 left me in the last race. I am now planning to purchase a new carburetor. But I wanted to ask your advice. What new carburetor do I need?
My engine config: 70mm piston, 54mm crank, 18cc head, 27.5mm inlet 25.5 outlet valve. The camshaft is standard but its base is reduced to increase the lift, now the lift is + 1mm (0.270) to the standard camshaft. Springs 36lb, HD champions rockers. ARC connecting rod, flywheel aluminum PVL. And it is used in karting.
I think the PZ30 is too big, I had problems with starting and unstable idle. But during the races, he worked confidently up to 8300 rpm and I liked it. And yes, I used a carburetor with an accelerator pump that gives an extra jet of fuel.
Now I am wondering if I can use the PZ27 with a booster pump for improved starting and stable idle. Or Try the PWK28 Carburetor? But it doesn't have an accelerating pump. I am afraid that this will affect negatively during the race.
